Had more time than normal this past year to operate backyard observatory (for reasons!). Just completed a 2022 summary report (because more reasons) so thought I would share here:
Imaging nights: 98
Targets: 35
Total subs: 4757
Usable subs: 2800
Discarded subs: 1957
(power lines, wx, tracking)
Usable imaging hours: 217
Average time / target: 6.2hrs
Some results turned out decent, others not so much :=)
These are from January.
Had fun chasing the "galactic wanderer" globular cluster (Caldwell 25, NGC 2419) early Feb 2022. It is located outside our galaxy! Further away than Large/Small Magellanic Clouds.
Here it is 'next' to small galaxy NGC 2424.
Also some other images from early February.
From February and March ... improved my game with respect to processing dual-band filtered images from OSC camera. Specifically L-Extreme and separating Ha, [OIII] channels early in processing workflow.
Here is Monkey Head nebula, M53 globular cluster, Thors Helmet nebula and Croc's Eye galaxy.
Making an effort to add #AltText for all these images. Hope they are sufficient for folks who use them?
The namesake (and construction supervisor!) for Jack Dog Observatory passed on in 2021. Beginning his journey back to the stars. He is missed. 💕
There is, of course, a new sheriff in town! Louie. 🐩

From March and early April.
Try to diversify targets when possible. In this case experimented using dual-narrowband on M97 Owl planetary nebula and nearby galaxy (M108). The galaxy looked terrible after processing (and thusly cropped out!) but the Owl came out decent.
Was particularly chuffed with the M109 barred spiral galaxy result. Moon is a single (and not particularly well focused) image.
Achievements in April:
First solar image of the year.
Capture of recently discovered super nova SN2022hrs (in NGC4647, next to M60).
Established 2 meteor cameras as part of the Global Meteor Network project.
The GMN cameras automatically capture 'transients' and forward data to a central server for processing. More info here:

Spring *is* #GalaxySeason so took another stab at Messier 51 Whirlpool. Happy with results - for a OSC camera. Next time, would like to try with a mono cam and add some Ha.
May marked the end of my "Elephant Trunk" project - this is a crop of result. Also took another stab at the Sunflower galaxy.
May 15/16 also marked a #LunarEclipse. Here is the moon as it nears full eclipse. This eclipse was noticeably darker than recent past eclipses.
As with most targets of the back yard observatory this year, 🔭 this M101 galaxy and Lion nebula were captured using Esprit 150, QHY128C and 5 minute subs. Processed in PixInsight. Have been trying for longer multi-hour total integration times, to improve signal-to-noise characteristics.
May also marks the start of camping season. Lucky this year to have had a seasonal site at my local #DarkSkyPreserve 🔭 🌃

Short summer nights mean limited imaging time, in my neck of the woods. Especially June/July.
Disappointed w/ Cocoon nebula result - dual narrowband filter not a good match for this target, IMO. Happy w/ the 11x5 minutes on Eastern Veil nebula.
Had fun capturing meteors of "new" Tau Herculid meteor shower May 30/31, for the #GMN. Apparently I "cannot attach video to a post already containing images" so will post that in a reply shortly.
... corresponding timelapse video compilation ...
