  1. Thats a cracking Gassendi image Pete. The 1.8x barlow looks to be a good match with your Asi174mm. But as you say the later 2 images probably a bit over powered for the conditions as I myself am finding out to my own detriment. It's still good to get out though and experiment with different setups.

  2. Yep lots of nice detail on show Neil even though the seeing was very jittery. There are great images to be had with the cassagrain once we can get some decent weather. Also good information above on the different ways to improve the capture data regarding frame rates gain etc. It is a constant battle just trying to find that sweet spot as nearly every clear night we get is always different. (Oh yeah It's always safer to stay clear of the edge very dangerous)😀

  3. Petavius crater captured monday evening 7-3-22 in very blustery conditions. Wiki describes this stunning crater as having a 170 miles diameter and a double rampart terrace rising to 11000ft.  The crater floor is convex rather like a crown bowling green where the central mountains rise up to 1.7kilometers above the surface. The crater also as a magnificent rille system with the prominant rimae petavius measuring 48miles x 1mile. This crater looked stunning on my laptop while capturing. So I would think this is a spectacular target for the visual observers.

  4. What a great effort Neil you are definitely inching your way to success in picking up subtle cloud detail. The second image is a little bit sharper especially on the limb area probably due to the black increase just the right amount I'd say. I can also definately see a very subtle shaded area. That looks like a very well spent £23 to me.

  5. I have just looked up your camera and YES you are correct the Asi120mc-s does have uv-ir cut filter built in. My mistake as I thought it was the standard Asi120mc. Anyway well done on your capture I will be watching the phases of venus with interest.
