Macro Video of C/2020 F3 (Neowise), KG Observatory, Julian CA. https://youtu.be/4Dv4lgP_JZQ/ https://www.astrobin.com/lrkv7i/ This is created from 66 x 60s exposures through a Blue filter for maximum contrast. July 23, 2020 from 9:06 PM to 10:17 PM PST. The comet was tracked with a direct drive Plan...

C/2020 F3 (Neowise) in 24". KG Observatory, Julian, CA. Now just barely high enough to clear the edge of the dome. Shot between 9:15 PM (19° alt) and 9:30 PM (17° alt). Then it's gone. Here the L600 mount tracks the comet's exact motion for maximum resolution during the 1 minute exposures. Star...

Pinwheel Galaxy (M101) from < 1" seeing. KG Observatory, Julian CA. Sorry, I'm a little late to the M101 party. (-: I wasn't planning on shooting M101 this year.But I changed my plan while working https://www.astrobin.com/3lr1yz/ . The seeing was just too good to pass it up. I could only get go...

The Needle Galaxy (NGC 4565). KG Observatory, Julian CA. While waiting for M16 and The Crescent Nebula to come into view during the June dark cycle, I'd aim for NGC 4565 from 9:15 PM (66°) to 11 PM (44°). My goal was to get very detailed in the center, thus only keeping the very best subs over a 10-...

Pillars of Creation - Ha-SII-OIII-LRGB Backyard Version. KG Observatory, Julian CA. Just an idea I had to do the Pillars of Creation in a more traditional way to help preserve the natural RGB with subtle Ha, SII and OIII highlights. I was hoping to get 5-minute Ha subs significantly below 2" FW...

With lots of luminance acquired during my Sombrero Galaxy (Deep) project looking for tidal streams... https://www.astrobin.com/ifvnh6/B/ ... I thought I'd spend another night acquiring RGB to produce this "Deep with color" version. With 30 minute subs, the core is saturated. Given that, HD...

M104 Tidal Streams. KG Observatory, Julian, CA

Several folks requested I update my prior FOV to possibly capture more tidal streams. 21.5+ SQM overhead skies, but closer to 21.2 SQM where I was pointing.

NGC 5426 and NGC 5427 (Arp 217). KG Observatory, Julian, CA. ESO selected this galaxy pair as their final image captured on their Very Large Telescope (VLT) before decommissioning their VIMOS instrument in 2018... https://scitechdaily.com/vimoss-final-image-interacting-galaxies-ngc-5426-and-ngc-5427...

Great Job! I believe there is a loop at the top as well, but i have not been able to confirm, maybe you can try for that but you will have to alter the FOV. Mark Hanson Thanks Mark! And thanks for pointing out your wonderful rendition. I often use your work for reference. I'm hoping to get more tim...

I think that what your image shows is very real. Compare your own image with this one by Benjamin Csizi. Ann Thanks Ann for the reference. That's what got me started on this. (-: I hope to go deeper this week to focus on that faint wide "road" from the galaxy, through those 3 bright stars...

Sombrero Galaxy (Deep). KG Observatory, Julian, CA. During this time of the year we see very dark skies due to a marine layer at lower altitude. That along with less lights during quarantine allows us to see 21.7+ SQM skies. (-: After seeing this deep exposure of the Sombrero Galaxy, I thought I'd t...

M82 (Pure, Deep and Final). KG Observatory, Julian, CA. My 5th attempt at M82 this year... PURE because I use a Lighten blend of Ha over RGB. I believe this preserves the RGB much more than a screen blend. DEEP because I use 20 hours of Ha in a 21.3 SQM sky. FINAL because I promise this is the last ...

NGC 5866 (M102 ?) Some astronomical historian argue that M102 is a duplicate observation of M101. Others say the evidence points to NGC5866. Maybe this is why NGC5866 is rarely imaged? This HST image from 2006 caught my attention... https://hubblesite.org/image/1933/gallery A FWHM of 1.86" on t...

M82 (Deep). KG Observatory, Julian, CA. Many thanks to Adam Block for lending me 56 hours of Ha data from his 32".
