NGC 4236 (Caldwell 3) is a barred spiral galaxy in the constellation Draco and is a member of the M81 (UMa) group of galaxies, which include M81 and M82. It's about 11.5 million light-years from Earth, has a diameter of over 140,000 light-years, and is believed to contain about one trillion stars.
I thought this was kind of neat since it's different than many of the other spiral/elliptical galaxies I've captured this season. Unfortunately, even with 5 hours on this target I didn't get the detail I was hoping for. Next year, maybe!
Capture Date: 5/9/23, 5/10/23
Askar 107PHQ
ASI2600MC Pro (OSC camera)
ZWO AM5 mount with guiding via ASIAir Plus using an ASI178mm mini and a 60mm F4 guide scope
Light Frames [Total Exposure 5:00] used Antlia Triband Ultra RGB filter -- 600s x 30 frames
All light frames calibrated with dark, flat, and bias frames
Pre- and post-processed in PixInsight
Additional post-processing in Photoshop for exposure adjustments and generation of jpeg

Greg, another nice one! Â You've been busy! Â Where do you find the time?

@terri Thanks, Terri. I think my wife considers herself an Astrophotographer's (if I can be so presumptuous) Widow. 😀 And I still have 4 or 5 more to process! I think I'm processed-out for the day, though.

They your wife probably likes the long stretches of bad weather... because you are probably inside more than outside at the telescope. Â Â Or maybe you're stuck in your study staring at pixinsight!
