IC 410 (Dec. 21. 2022, reprocess of Nov. 2020)

This image is 63x15" (15.75 hours) with the 203mm f/4.95 Synta-ONTC Newtonian, an Astronomik CLS filter, and Atik 460 EXC camera.  The prior version appears here: https://polarisb.blogspot.com/2020/12/ngc-1893-and-sim-129-130-nov-2020.html.

M20, early 2022 (re-process of May 8, 2022)

This image is constructed from data gathered by Insight Observatory's remote telescope AFIL-2, a Skyrover 130 APO located at Yunling Observatory, China.  Data for this image includes 3.75 hours of exposures: 1.5 hours (18x300") through a red filter and roughly equal exposures taken through green and blue filters.

Mars & Luna Video (Dec. 8, 2022, around 3 a.m. UT)

I posted a video of what the conjunction looked like through my wonderful 6" f/8 Newtonian, just before closest approach.  This little video link stays very small, though.  To reach the actual posted video, click here: https://youtu.be/EoYgxrQj_YI.  That will take you to the actual video posted on Youtube, which is much more like what I saw in the eyepiece.

Mars & Luna (Dec. 8, 2022, around 3 a.m. UT)

 

These are best 50% of a couple of 300-frame SER videos made with the QHY 5iii485c camera through my wonderful 6" f/8 Newtonian with Spooner-finished mirror.  The light from Mars took 4.57 minutes to go from Mars to Earth and the light from the Moon took 1.32 seconds. Moon, 395300 km; Mars, 82.2 million km.  So by the time I took this picture, Mars had moved.

Below is a single frame, perhaps the best of the night.
