I am still working on the Heart Nebula mosiac I started shooting the first few days of the new year.  Plenty of work left, but I at least have a more complete image at this point.

Over 4.6 hours of integration with a variety of exposures including 3 min, 2 min and 30 sec sub-images. All were taken with a QHY183c camera at -20C or -15C cooling, an Optolong L-eNhance filter and a Televue TV-85 at F/5.6.

The December 26/27 weekend of 2020 was the last imaging session of the year.   I managed to bag good data for all the objects on this page.   The Heart and Soul Nebulae are still works in progress, though.

I had a little trouble with streetlights and two satellite trails for this shot, but I salvaged what I could.   I like the way the 3 minute sub-images are working out, though, now that I’ve tuned the guiding to get usable subs at that exposure setting.   That exposure seems to be the sweet-spot for this camera and filter combo at my location.

Below is the image above, but with data add in from my last imaging session of it from a full moon night on Halloween, 2020.   I like the way the portrait and landscape versions had diffraction spikes at 90 degrees to each other:

What started out as a quick imaging session to just take a look at this turned into a multi-hour session.   I did 3 one hour stacks and one with 45 minutes, with one of those 1 hour stacks shot with the 30 second subs,   A nice haul of good data that was easy to process.
