Galaxies

As for the Latest page, the most recent images are at the top of the page.

I was away from home most of the Summer (see the Eclipse 2010 trip), and the Autumn weather was disappointing. This small but beautiful galaxy, magnitude 10.2 NGC 7217 in Pegasus was a real challenge. I tackled it on three separate nights, but seeing conditions almost defeated me, and the only really worthwhile luminance data was 4 x 20 minute frames from the early hours of 30th August 2010. But it proved just enough to tease out the fine detail . RGB was only 3 each at 5 minutes binned 2x2. ST-10XME with AO-8 on 12" LX200ACF at f10.

Well, the Milky Way is a galaxy, as are the Magellanic clouds! So I feel it only right to include them here, these being the only shots I have of the Southern sections of our home galaxy.

During my extended holiday including viewing the 2010 Solar Eclipse in the South Pacific, it was always my intention to photograph the Southern Milky Way, not only in wide field, but also with some more close up images using my 400 mm Canon lens. I had no opportunity during our stay on Tahiti and Moorea, and for most of the following two weeks on New Zealand the Moon was intrusive. Towards the end of that stay I obtained this image from a dark camp site (we were in a camper van) at Fairlie in South Island. Lots of trees unfortunately, and the Moon rose before I could go for close ups. But good views of the Clouds of Magellan, the Southern Cross, the Coalsack and Carina nebulae. Composite of 5 x 5 minute exposures at ISO800, Canon 350D and Tamron 17-50 lens at 17 mm and f5.6 Full Size

Later in the holiday we stayed with relations near Launceston, Tasmania. With four nights there I expected to be able to enjoy the night sky - New Moon and a dark site. But it was not to be - cloud and rain alas. The only remaining opportunity was from the next stop with relations on the Gold Coast near Brisbane. But there was light pollution and a brightening Moon. Nevertheless I obtained this pic of the heart of the Milky Way - a couple of constellation figures in for identification. Canon 350D, 5 x 5 minute sub frames at ISO 800, Tamron lens at 17 mm. Constellation figures also on the medium size image (click on thumbnail).

Full size. 

All the 17 mm shots were taken unguided on my EQ3-2 mount - the mount tracking was accurate enough at the short focal length, and I had a good Polar alignment. So to finish off, I zoomed the lens up to 50 mm, just for a try. And indeed the unguided tracking was also good enough at that focal length. This shows the Southern Cross and Coalsack area. So although I had a guide camera with me, I never used it. Full size.

I guess I'll have to return South some time. Maybe in 2012 for the Transit of Venus !

NGC 4438 (the larger one) and NGC 4435 , 'The Eyes' in Virgo. The extreme distortions of 4438 are probably due to the proximity of 4435.

Although it looks as though this image is vignetted, it ain't! See this image from the ESO. But because I only had limited data, mine is rather 'noisy' in comparison! Included here although not a particularly good image, because never possible from the UK!
