Sol (July 31, 2023)

I am thinking of the upcoming eclipses.  This is 1/4000, a single frame, with a Canon T3i and a SW80ED, processed in DPP and PS.

NGC 1555, Hind's Variable Nebula (data from 2021)

 

I've wanted to collect on this target for a long time.  It's actually positioned over my latitude, but it can't be shot from the suburbs easily.  I tried to shoot this once and only collected the brightest part of the nebula in a noisy and grainy stack.  So someone else whose telescope is in the southwest Utah desert collected this data, and this is my rendition.

This is 100 minutes of Lum combined with 50 minutes each of RGB from Starbase's ATEO-1 telescope, a 16" f/3.7 Dream Aerospace Systems reflector.

M65 (Spring 2021)

M65 is a favorite to observe and to image.  I saw the galaxy a few nights ago from my backyard with a 6" telescope at 120x.  It's thrilling to see light that has traveled 35 million light years, or so, and realize it hits my own retina.

Here is an earlier image with a 10" reflector:

And another in 2019 with an 8" reflector:

This latest image is from very fine AG Optical data: 22 x 300 each of RGB and 81 x 300 of Lum.  It's better data than I've used in the past, and it's better color.

M35 & NGC 2158 (Feb. 2023)

I tried several times to see NGC 2158 with a telescope from the suburbs.  My wonderful 6" f/8 would only show me one star.  My C8 would show me that star and hints of two others.  My CFF 290 Classical Cassegrain would show me those three and a glow with averted vision, on the night I tried it.  With a camera on a small scope, the cluster stands out. This is just 16x600" with the Atik 460EXC through the SWED80 at f/6.375.  I am always impressed with the optical quality of the ED80, and the flattener/reducer does a superb job.

NGC 663 (Sept. 2022)

I've always liked this cluster through the telescope eyepiece.  This is 22x300" with the Atik 460EXC through an Astronomik CLS filter and the 203mm f/4.95 Synta-ONTC Newtonian flattened with a Baader MPCC (Mark I, the old version).  I took this in September but did not get around to processing till now.

M38 and NGC 1907 (Jan. 2023)

 

This is 19x600" with the Atik 460EXC and LPS-P2 through the SW ED80.  Which is better, the more stretched shot or the less stretched one?  The less stretched one is closer to what the area looks like through a large telescope.  The more stretched one shows stars as deep as 17th magnitude.

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.
