I tried out my new 127/1200 refractor yesterday for a bit of calcium, I thought stopping down to 60mm would be fine, but the seeing really was that bad, realistically I should have stuck to 40mm. My plan is to have range of scopes that will be stopped accordingly to match the sampling of the pixel size of the camera used, with the size of the scope matching what the seeing allows. I plan to use this scope and camera combination at 72mm which will give me f16 at the filter. I had to do a lot of psot processing to salvage this image, normally my calcium images are minimally processed. Even with dodging snow showers to image it is worth it!
