I imaged the conjunction around 17.30hrs GMT with my Startravel and ASI120MC camera on the SLT mount (+fixed wood tripod). The image scale with my C8 would clearly have been too large.
The image, processed in Registax6 from 200 frames, is shown below. The image is shown horizontally flipped to match the telescopic view with star diagonal. I puzzled for some time over what exactly I had captured, but the centre dot is Mars (overexposed) the faint dot at lower L is Neptune, and the brighter dot at upper R is the star 81 Aqr. I also took a run which has Mars only slightly overexposed, and looking very small, and inevitably not capturing Neptune.

so i got out my celestron sky prodigy mak-cass and took a look at neptune, but i only saw a little point of light. it had a definite bluish tint, but it did NOT look like a planet. is this just normal or is something wrong? i didn't get a picture of it, i was going to try but i forgot. any tips?
A clear night sky and lots of free time were a recipe for a satisfying night of observing and imaging with my Mak. My imaging targets were the freshly opposed Uranus and its more distant cousin Neptune. A trick I use to find Uranus is to star hop from Hamal to Sheratan in Aries to Eta Piscium and Omicron Piscium in Pisces. Uranus is just above Omicron. This is a single 2 second exposure at ISO1600:
Neptune was a little trickier to image as I only had the viewfinder on the scope to guide me and Neptune was undetectable through the camera. I had to point the scope in the general area that I knew Neptune was in, using Lambda Aquarii as a guidepost, and I took several test shots to look for familiar star patterns. But, I got it, using a 10 second exposure time at ISO1600:
Had a great night imaging and star chasing, and even saw an Orionid before all was said and done!
Clear skies to all,
