Lunar Images
This Last Quarter Moon was one of the first photographs I took with my Celestron SCT in September 1999. I used a small semi automatic compact, a Vivitar 35EM, afocally with a 26 mm eyepiece, and ISO 200 colour film. Unsharp masked. This image appeared monochrome in the July-September 2007 issue of the SPA magazine.
The early morning of January 21st. 2000 saw a beautiful clear sky and a deep red total eclipse of the Moon. The magnitude 7.6 star TYC 1385-1065-1 was due to be occulted during totality, and I was able to capture the approach in these three photos. They were taken with the Vivitar 35EM compact afocally with a 26 mm eyepiece. ISO 200 film, approx. 10 second exposures. Slightly out of focus unfortunately. (Well, it was after 4 am!). The instant of occultation was timed at 0416.58 at Boldon, Tyne & Wear, England. These photos were published in the June 2000 issue of Astronomy Now as Picture of the Month.
After I got the VCam the Moon was an easy target to practice on. Note that most of the VCam Lunar images have been converted to greyscale. Occasionally the camera introduces false colours, particularly on the highlights, and of course the greyscale images take less time to download.

January 26th. 2000. There was a clear waning gibbous Moon, and I took a number of images along the terminator which gave this mosaic, stitched together in a venerable (1993) version of Picture Publisher. |

While the Moon always turns the same face to the Earth, nevertheless the view is not totally static. It appears to nod rather like a toppling gyroscope, a phenomenon known as 'Libration'. This allows us to see more of the Moon's surface than would otherwise be visible. The effect is shown by comparing this image of Plato (unfortunately not quite as crisp as the other one) taken on May 12th, with the above February 13th image - the Moon appears to be tilted at a different angle to the Earth. (But if I've misinterpreted these images, someone please tell me - I'd hate to mislead anyone.) |

Although I had a good image of Theophilus and friends from the 26th. January session, this one from 11th. March 2000 is better! |

This photo was taken on 20th. April 2000 through my recently acquired Celestron Wide Angle Telescope. At prime focus, the image was just too large to fit on the chip in one frame, so two shots were taken then stitched together. Not quite as crisp as the C8 images, but the nearness to full Moon does not help the contrast. |

A month or so later, with the Moon closer to full. Not as crisp, but until I get a better chance ..... Nevertheless it's interesting to see how the lava of Mare Humorum just entered the crater Gassendi (at the top of the picture) and half drowned Doppelmayer (bottom).
-
Actually the seeing was good, but the Moon was quite low in the sky (altitude 20 degrees), so the thickness of the atmosphere affected the image. A collimation check using Arcturus (much higher at 50 degrees altitude) proved good collimation and steady sky, as seen by these three consecutive out of focus patterns:

-
The following night with the Moon almost full, it was even lower in the sky at 16 degrees altitude when the following shots were taken. I was after Schröter's Valley, and got a picture, but not very good - the light angle was not ideal, and the atmosphere was murky. But there was a reasonable view of the interesting crater Wargentin next to the large walled plain Schickard. This crater filled with lava from the inside, and forms a plateau above the surrounding terrain. The mosaic is of the general SW terminator. When the Moon is higher later in the year, I'll repeat these shots and hope for better definition. LATER! See below for Schröter's Valley!

The small hours of 20th. August gave a clear sky with good seeing and a bright waning gibbous Moon. I imaged most of the terminator, and a couple of sections are also shown in more detail. If you want to view the enlargement of the terminator, please be aware that it is 74 Kb in size. ------------------- - Aristoteles and Eudoxus ---Ariaedeus Rille and part of Hyginus Rille |

After over a week of cloud, during which I built my dew heater and distribution panel, I finally got an opportunity to try them out when the sky cleared for a short while in the early hours of September 17th. 2000. Before they rolled in again, I managed to image part of the terminator of the waning gibbous Moon, in quite good seeing. The dew heater did a grand job!

The following evening, September 18th, the terminator had moved on to give a nice grouping of Plato, the Alps, The Alpine Valley, Aristoteles and Eudoxus. The seeing was again quite good, and I couldn't resist it! |

Ever since I started imaging the Moon, I have wanted to capture Hadley Rille. But the excellent conditions needed for this difficult subject never coincided with the required phase and personal availability. Until March 3rd. 2001! So here is the result of that imaging session. Not only did I capture a decent image of Hadley Rille, but also Rima Birt, the rille parallel to the Straight Wall and three craterlets in Plato. All images taken with my LX90 SCT and Vesta Pro Web Camera at Cassegrain focus with 3x Barlow, stacked in Astrostack, final processing in Adobe Photoshop.

A long time since I've done any Lunar imaging, but on 8-9th November 2006 I was set up for a deep sky target. When I'd finished, the waning Gibbous 18 day Moon was well positioned, and fitted nicely on the Artemis chip with the TMB refractor. So I imaged it in Hydrogen alpha light which nicely brought up the shading in the Maria. The larger dynamic range of the Artemis over a webcam gives a more natural appearance, but it's not possible rapidly to capture numerous frames. Nevertheless 10 out of 14 frames were good enough to stack, and this is the result. |

The 3rd. of March 2007 provided a total Lunar Eclipse over all of Europe. I was on a ski holiday in Zermatt, but was favoured with clear skies and obtained several frames at different stages. Unfortunately I only had a moderate quality 300 mm lens to use with my Canon 350D camera, and that coupled with the fixed tripod meant that the longer exposures and noisy setting for totality (2 seconds at ISO 1600) prevented me getting detailed photographs. Nevertheless a reasonable record. It was also clear in the UK - had I been at home with a driven mount it would have been a different story..... |

Although the close up is very lacking in detail, it is worth noting the presence of relatively faint stars either side of the Moon. 5th. magnitude 59 Leonis and 6th magnitude 56 Leonis respectively left and right. |
|
|
A wide field 30 second image showed up numerous stars, the constellation Leo (with Saturn) dominating the scene, Coma Berenices upper left. Annotations if you 'Mouse over' the enlargement. |
|
|
A couple of nights later, although with thin cloud, from my hotel balcony I obtained this photograph of the superb Matterhorn lit by moonlight, with the constellation of Orion to the right. |

A Moonbow! Taken around 7.30 pm 23rd January 2008 . The almost full Moon was in the East at approx. 12 degrees altitude, and produced this faint rainbow in the Western sky :-) It lasted for a full 20 minutes, but I was on my way out, so just hastily set up my camera and grabbed a few frames. Made me late anyway!! Single 30 second exposure, Canon 350D at ISO400, 18 mm lens. Noise reduction in Neat Image, levels in Photoshop. A car went along the road during the exposure - you can see brake lights, and some illumination of the trees from the headlights. The camera was only slightly tilted - the ground does actually slope away to the North. The star in the top right corner is Deneb. |

My camera lens although 18 mm (equivalent on the Canon 28.8 mm) still wasn't wide enough to capture the full arc in one frame. I took a second frame of the rest of the arc, but the camera wasn't quite level, (working in a hurry, in the dark, in a field!) and the stitching program had a bit of trouble with lack of detail high up. Also slight problems with brightness levels. But for what it's worth....... This image appeared in the April 2008 issue of Practical Astronomer |

A bright Moon generally spells death to deep sky imaging, other than narrow band filtering. But of course the Moon itself is a wonderful subject - bright so ultra short exposures, contrasty and easily found! So the night of 16th February 2008 found me imaging it with my Artemis 285. Full frames take around 12 seconds to download, so taking hundreds of frames for stacking is out of the question. But careful choice of a few good frames works quite well, and with decent seeing a good result can be obtained. One advantage of using the 16-bit Artemis is the much improved dynamic range, producing a natural looking image. This one shows the upper part of Mare Imbrium , featuring Sinus Iridum to the left, and crater Plato with the Alps. Full Size (321 KB) |

Then towards the South of the Moon, a study of the huge crater Clavius with Tycho above. Even in this gibbous phase the streaks of ejecta from Tycho are clearly visible. Both these images were taken with the Artemis 285 and 12" LX200 ACF at f10. Individual exposure times 1/50th second. I used a Red filter to improve contrast. Full Size (547 KB) |

The early hours of 21st February 2008 saw a total Lunar Eclipse. But not for me! Out of 9 clear nights there was only one cloudy one, the 7th of the nine and it was the night of the eclipse. Typical!! And there isn't another full sequence visible from the UK until 2015. But a couple of days earlier (19th February) ice clouds high in the atmosphere produced a beautiful Lunar Halo which I was able to capture. Canon 350D with 17 mm lens at f7.1, single 30 second frame at ISO 200. Hot pixels removed in Photoshop, smoothed in Neat Image. You can see the Sickle of Leo and Saturn lower left inside the circle. Castor and Pollux top right, Procyon to the right. The halo is produced by refraction of Moonlight at an
angle of approximately 22 degrees, so the diameter of the
halo is always 44 degrees. It just fitted in the field of
view. A few weeks later during the visit to Kielder (below)
I obtained a photo of the similarly formed
Solar Halo. |

During the 2008 Spring Kielder Star Camp while staying at Calvert Trust, the Sunday (6th. April) night promised a very young New Moon, but unfortunately the sky never cleared. And remained mostly cloudy for the rest of the stay at Kielder. But a brief glimpse of the New Moon the following evening yielded this nice Earthshine photo. Canon 350D, single 4 second frame at ISO400. Larger image. |

The weekend of 28th March 2009 was the climax of the annual Spring Kielder Sky Camp. I and some friends stayed in a log cabin for most of the preceding week, but our heart went out to those camping - Thursday and Friday were cold and wet in the extreme! Even the earlier part of the week afforded only glimpses of the night sky. But Saturday evening opened with a beautiful thin crescent Moon in the western sky. This photo, taken with my Panasonic TZ5 digicam shows the Moon with Earthlight hanging above the trees to the west of the cabin. Reminiscent of the above, taken a year earlier! |
|
|
I had my Meade Series 5000 127 mm refractor with me on my EQ6 Pro mount, and the crescent fitted nicely into the field of view with the ST10 XME. So using a Hydrogen-alpha filter to reduce the glare I was able to obtain this image. This is the best frame picked out of 10 x 1 second frames. (Combining produced a less crisp image). |

During the 2009 Spring Moonwatch week (part of the International Year of Astronomy) I was on holiday for a few days in Ambleside in the English Lake District. I took a telescope along with me in the hope of 'wowing' some of the guests at the hotel with a closeup of the Moon. And I wasn't disappointed! Over the four nights I was there about 20 guests took advantage of the opportunity, and only one of them had ever seen the Moon through a telescope before. Saturn was also on show and elicited exclamations of wonder, although appearing very small at the maximum 81x magnification available using a Hyperion zoom eyepiece (8 - 24 mm) on my 4" TMB refractor (650 mm focal length). Some nights were rather hazy, but Thursday 2nd April was beautifully clear with good seeing, and several guests took the opportunity to photograph the Moon afocally with cameras ranging from mobile phones to full size digicams. I also obtained a nice image with my Panasonic TZ5 digicam. Of particular interest was the bright spot of crater Ammonius catching the rising sun within crater Ptolemaus while immersed in the pointed shadow of a high mountain on the main crater wall. Here. A number of guests departed vowing to buy a telescope - definitely a successful Moonwatch! This was later featured in the John Lewis Partnership House Magazine 'Connections' for July 2009 and in the July to September 2009 issue of the SPA magazine. |

The weather in December 2009 was very poor, culminating in a heavy fall of snow on 19th. And in the rare clear intervals, the Moon was brightening so no deep sky work. But on New Year's Eve there was the second full Moon of the month - a 'Blue' Moon. And to add interest there was also a partial eclipse. Only a small Umbral effect, and because of clouds I only managed to capture a few frames. This was the best, taken with my Canon 350D on the Meade 80 mm f6 refractor at prime focus (cropped from the full frame). Single frame, 1/640sec at ISO200. |

In October 2010 a friend of mine asked for a pic of the Full Moon for some students. Unfortunately I was away from home on 23rd October, but managed a shot on the night of the 24th. 96%, waning. Nice view of Mare Crisium. Single 1/500th second frame with modded Canon 350D on Meade series 5000 127 refractor (950 mm fl). Slight sharpening in Photoshop. |

On December 21st 2010 just before dawn there was a total eclipse of the Moon. Visible from the UK, but only just as it set in the West. Fortunately it was a beautifully clear morning (but bitterly cold at -10 deg C) and despite a mishap with my EQ3-2 mount I was able to take some photographs. All with my Canon 350D and 400L telephoto lens, ISO200 and f7.1 Full sizes: 1 1/250 sec. 2 1 sec. 3 2 secs. 4 3.2 secs. As I was lifting everything over a farm gate across the road from my home to give me a clear view from a public footpath the whole bl**dy thing fell over - the gate that is, with me on top and the mount underneath. It was just leaning against the gateposts with no hinge, not even a bit of binder twine!! And of course in the dark I didn't realise until it was too late. So one damaged and unusable tripod. Although the camera and lens were attached to the mount head, fortunately the damage was limited to the tripod. I also have an EQ6 Pro mount - my 'Star Party' mount. So out of the box in my garage and set up. But time lost, so I wasn't ready until almost 7 am by which time the Eclipse was well advanced. Nevertheless, although I didn't get a full record of the early stages, and by totality it was only 6 degrees above the horizon and dawn was breaking, I'm happy enough with what I did get. And thanks to help via the 'net I've got replacement parts to repair the damaged tripod. On checking with Skymap to be sure that what looked like stars *were* stars, it's interesting to think that the only time you'll get to see a mag 7 star occulted by the Full Moon is during an Eclipse! The star at 4-o-clock in the bottom frame was behind the Moon two minutes earlier. It's mag 7.84 TYC 1863-1976-1 Unfortunately because of the accident with the mount I don't have a photo before the Moon occulted it, although at that time (0652) the Lunar limb next to the star would have been in the Umbra. |

Unfortunately the wide angle shots I took (50 mm Zoom) were slightly out of focus. But for what it's worth, here is one, showing the totally eclipsed Moon over the snowy landscape. |
