Had a productive, non-cloudy night last night. The seeing was considered poor (2/5). Everything else was pretty average. I'll take it though, I'd rather image and observe than sit inside and just think about it. I imaged early in the evening, around 7:30pm to 8:30pm roughly. Was fairly cold. Didn't have to deal with my heaters or anything. Literally just turned on the mount, go-to aligned just for simplicity, threw on my bahtinov mask so I could focus on one of the alignment stars, then moved to the moon and started videoing it. I had to refocus once or twice. I think the objective being exposed to the colder air over time caused focus to shift. Later I threw on the barlow to try some crater detail, despite poor seeing where that is the limit instead of aperture. Managed to squeak out some decent details with lucky imaging.
This is with a smaller, inexpensive telescope, cheaper than most half decent camera lenses, and a camera that is cheaper than an entry APS-C for the most part. I do this as a challenge, and out of budget constraints. But the point is to show what can be done with very modest equipment, but in context, right tool for the right job applies here.
Celestron C6A (6 inch SCT; 1500mm F10) ($399 scope)
GSO 2x Shorty Barlow
ZWO ASI178MC (6.4MP CMOS) ($369 camera)
SharpCap 2.9 (everything is 2,000 frames, best 20% stacked in AS!2, Wavelets in R6, CS5 for final processing)
What this looks like:
Full mosaic. Waxing Gibbous at 88% full. This is a mosaic of 11 separate panels. This was taken with only the SCT and ASI178MC, no barlow involved, so 1500mm F10 and the camera naked together. Final image is 7,000 x 6,000 pixels, or 42MP.IMAGE LINK: https://flic.kr/p/NPW5wm LunarMosaic_12102016 by Martin Wise, on Flickr
Detail panels of larger craters. These were created with lucky imaging. This was done with the 2x barlow (1500mm F10 becomes 3,000mm F20) and the ASI178MC. Again, 2,000 frames captured and the best 20% are stacked. Lucky imaging heavily applies here as seeing was poor (2/5), so seeing was the limit, and not necessarily aperture (though I was oversampling at F20 for my pixel size). This was mainly to experiment and stress the system in conditions that are not ideal. I don't think I can get anymore resolution on these craters except on the best of seeing days, as I'm well past the limits of my aperture here.IMAGE LINK: https://flic.kr/p/PTfQgb Tycho_Crater_12102016 by Martin Wise, on FlickrIMAGE LINK: https://flic.kr/p/NSEg6v CopernicusCrater_MontesCarpatus_12102016 by Martin Wise, on FlickrIMAGE LINK: https://flic.kr/p/PxjZNs GassendiCrater_MareHumorum_12102016 by Martin Wise, on FlickrIMAGE LINK: https://flic.kr/p/NPRZuA Plato_Crater_Alpes_12102016 by Martin Wise, on FlickrIMAGE LINK: https://flic.kr/p/PVY4KF Schiller_Hainzel_Craters_12102016 by Martin Wise, on FlickrIMAGE LINK: https://flic.kr/p/NPS3j3 PhilolausCrater_12102016 by Martin Wise, on Flickr
