Title: Lunar imaging with ZWO ASI120MM camera
Post by: oldfrankland on October 31, 2016, 02:51:20 PM
Recently picked up a 120MM camera for solar imaging, but first opportunity to use it was on the moon.....got pretty hung up on the results.....still haven't done any solar imaging.  The 1/3 inch CMOS detector seems to perform as well as my DMK CCD cameras.  The image scale at prime focus with my C925 seems a very good match.  In recent weeks we've had some good to very good seeing conditions in Livermore.  For $260, from OPT, the 120MM is a steal....in my humble opinion.  You can see more than you are probably interested in at my 2016 lunar imaging web page at:  http://www.lafterhall.com/lunar_astrophotography_2016_jim-ferreira_001.html (http://www.lafterhall.com/lunar_astrophotography_2016_jim-ferreira_001.html)

Gorgeous!  I especially liked the shot of the Alpine Valley Rille on your website.  That rille is on my visual observing bucket list.

It would be interesting to see side-by-side comparisons of the 120MM and DMK images taken at (nearly) the same time on the same object.

How much processing do you do on the 120MM images?

Definitely nice pictures there.

Hi Jeff, thanks for the thumb up on my lunar stuff.  Each of the cameras have different size detectors so side by side comparison would be kind'a apples and oranges.  All the AVIs (2000 to 3000 frames) are processed with AutoStakkert2, typically for the best 200-250 frames, then sharpened in RegiStax5 using wavelets, finally, some adjustments of brightness, contrast, etc., in Photo Shop Elements.  Pretty straight forward.  Good seeing conditions are really the trick, and I've been fortunate of late.
