Pictures made with my antique refractor

The first three pictures were made on the same night, 25th February 2004, using my ToUcam 740K at the prime focus. The picture of the Moon is a mosaic, reduced to 20%. The pictures of Jupiter and Saturn were made by allowing the image to drift through the field of view, moving it back whenever it got close to the edge. A number of frames had to be removed during processing.
The fourth picture was taken on 6th August 2004 using the setup shown in the picture on the previous page. In this case I guided the telescope continuously by hand. The fifth picture was taken with my ETX125 as a comparison.

Jupiter and Saturn Jupiter and Saturn. I managed to stack 296 frames for Saturn (out of 1917) but only 70 for Jupiter.

Moon mosaic The Moon at 5.1 days. This is a mosaic, reduced to 25%, made by the drift technique described by Jan Timmermans. The avi was shot with low gamma but this was increased to 2.00 after processing and a small amount of unsharp masking was applied.
It is interesting to compare this image with the 5.4-day Moon on my Phases page. The libration was quite favourable here but very unfavourable there.

Sun The Sun taken the same day that the photo of the telescope was taken (6th August 2004). This is sunspot number 10655.

Sun And here, for comparison is the same sunspot group taken about 2 hours earlier with my ETX125. This telescope has a slightly longer focal length, so the image is a little bigger but they are both about f/15.
