I decided to take out the Questar Q700 89mm f/8 telephoto lens tonight and pair it with the ZWO 178MM mono camera. I wanted to try and capture the Moon. I will say that obtaining critical focus was a challenge, or it could have just been the lens still acclimating to the outside temps.
Anyway, here is the result of taking a short 1 minute video and stacking the best 50% of the frames. I could only achieve 12 fps at best because I had to utilize the entire size of the sensor which can really slow things down. At 640 X 480 I can sometimes achieve well over 200 fps. So, big difference there. Slower frame rates means there's less of a chance to freeze the seeing and obtain sharp frames to stack.
Here is the result. I will say that the small size of the Q700 is really nice and the hassle factor is low. So, I take that into consideration and keep my expectations realistic with regard to imaging with it.
Processed with Autostakkert, Registax, and Adobe Lightroom. The final image was downsized and converted to png for posting. It will definitely look sharper if you click and open it versus the compressed preview image.
Thanks again for encouraging me to get out there!
