Ring Nebula – M57. Taken on Jun 20, 2020. 48×15 sec, QHY183c at -15C cooling, Gain 42, Offset 100, Baader UHC-S filter, Televue TV-85 at F/5.6, Atlas EQ-G w/EQMOD. SharpCap 3.2 LiveStacking and PHD2 Guiding with dithering on. Metro area, Bortle Red Zone, below average transparency .

Friday night, Jun 19th, 2020 was warm and muggy and clouds persisted till after 9:00 PM.  It was predicted to clear, so I went to bed early and woke up just before 2:00 AM and setup my scope then.  It was clear, but the transparency was poor and the humidity was still high.

I managed to get a decent amount of data on two objects, and I also peeked at 2 or 3 other things in between.   M22, the globular cluster in the first image, was a secondary target and I really wanted to get the Omega Nebula and the Trifid Nebula nearby.  My narrow window to image them was so small, however.  Trees and streetlights were in the way.   By the time I was ready to shoot, that area had moved out of position.

I had imaged M22 a few times, but with other scopes.  I took all the data I had on it and recombined it to produce the 2nd image above.  It is data from an 8″ Schmidt-Newt and a 6″ Schmidt-Newt, along with the data from the first image above.

The Ring Nebula was a quick peek that turned into a usable image.  The full size image is a crop at 100% resolution of the central area.  I was hoping to pick up that galaxy that is nearby to the Ring, but 48×15 sec sub-images wasn’t enough to bring it out.

It looks like I need to get out of the big city to get the summertime nebulae targets like Omega and the Trifid.  Late June and early July sometimes has clear skies and hopefully I’ll be lucky and get to a dark sky site before too long.

The Crescent Nebula From a Metro Area

The Crescent Nebula. 433×15 sec (1.8 hrs,) Gain 42, Offset 33, QHY183c at -15C, UHC-S filter, Televue TV-85 at F/5.6.

I think the last time I shot this was in 2014.   This would be the first time imaging it with my new QHY183c camera.   Not too bad for only 1.8 hours of exposure.  Plus, it was very short 15 second sub-images, which kept the stars nice and tight.

The Jet from the Black Hole in the M87 Galaxy!

I’ve tried this before with little success, but this time the jet of M87 shows quite well in this nearly 1 hour exposure.  The amount of energy to shoot out a jet this long is enormous!

It even shows the characteristic blue color of the synchrotron radiation of electrons spiraling in a magnetic field.

Supernova in M61! Another M13 Globular Shot, Too.

I imaged the galaxy above and the globular below on Sunday, May 10, 2020.  Very nice weather that day and a pretty good evening, too.   Being I had to work the next day, I cut the session short and only got data on two objects.

Imaging Session April 30, 2020

M63, the Sunflower Galaxy. 121×60 sec @ Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6
M5 Globular Cluster.. 172×60 sec @ Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6
M27 Planetary Nebula. 60×60 sec @ Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6

The Sunflower Galaxy was the second time this year for imaging it, so I combined the two data sets and got this detail view below.  It is 3.77 hrs total time:
