Uranus and it's Ring

Several alterations to my system were made to improve the chances of another Uranus ring capture, these included swapping the 1.25" 5x TV Powermate with a 0.8x Focal reducer for a 2" 4x TV Powermate without a Focal reducer the idea being that less glass may reduce glare. The 685nm filter was used instead of the 610nm also to help reduce glare and a repaint of flat black inside the scope to also prevent any stray reflections. Waiting for another night of excellent seeing is often fruitless however the seeing gods must have thought after nearly a month had gone by it was my time again. The camera was rotated 15° from the previous position and particular attention was paid to the histogram level making sure it was about 90% but never went over 100%. An animated gif can be seen here http://www.acquerra....A-685-blink.gif kindly produced & provided by Anthony Wesley on his web page, however I suggest you may find it helpful to first try finding the ring which is both faint and narrow .Using these techniques with precise collimation and careful focusing I look forward to another capture if and when the seeing gods co-operate.
Regards, Phil

Nice work. I get the distinct impression this was very difficult to capture.

Yes indeed, to get that quality of ring detail is usually the domain of pro telescopes larger the 1mtr
