I've decided to take on another subject while it was high in the sky. Because of rains and clouds and work, I only had 4 hours on it, over 2 days from Bortle 7-8 area. Though it's buy one get one free kind of things with proper framing. Pacman Nebula and Ghost of Cassiopeia from constellation of Cassiopeia, my 2nd or 3-rd favorite asterism in the sky. Shos with Canon T3i, 135 mm at F/2.5 and ISO 1600, through L-Enhance. #astropic

Another experiment that sat on my drive for a while, I think it's about 10 hours of total exposure 4Ha + 6 through L-Enhance filter on stock Canon camera. I've learned that I'd probably need more time for individual exposure with Ha. NGC 7822 aka Teddy Bear Nebula. Shot with Canon 3ti, F/2.8 135mm, L-Enhance and Ha filters. #astropic

I was not satisfied with the result and decided to reprocess California Nebula and NGC1499. Here is what I got in a second try. #astropic

What did I learned photographing California Nebula. Main lesson is photographing DSO shoot for a objects higher in the sky. Here is 8 hours of NGC1499, from Bortle 7-8 zone, shot with Canon T3i, 135mm F/2.8, ISO 1600 with L-Enhance filter. #astropic Additionally RaspberryPI are very good tester of powerbanks :D as heart of my rig is RPI with KStars/EKOS/INDI

Clear skies around new moon let me take a picture of Andromeda Galaxy, M31 our nearest neighbor and few other galaxies made it into the shot. This was shot with Canon T3i, 135mm F/2.8 lens, ISO 100 from Bortle 7-8 area. Processed in @Siril_Official #astropic #astrophotography

We had few nights with clear skies so I took advantage of that and shot object that I wanted since last year: Heart and Soul nebulas aka IC1805 and IC1848. Shot with Canon T3i, 135mm at F/2.8, L-Enhance filter from Bortle 7-8 sky and quickly processed with Siril. #astropic

Started new project yesterday, something I wanted to shoot last year, but at the time were not skilled enough to pull it out, well now skills and equipment is there so this is my starting point.

Any eclipse actions? First time shooting it. Shared experience with people at the local library.

What you've been doing last night? I've been taking some lights on NGC7822 with this guy. It's very versatile and super portable. Runs on Raspbian with semi modern Kstars/EKOS/INDI and I love it.

I have decided to run an experiment: capturing Ha with a stock DSLR. Stock DSLR typically blocks 85-75 % Ha light, then given the structure of a sensor in the color camera, which DSLR is, you would only capture 1/4 of the light reaching filter. So I put Ha clip-in filter into my stock camera and embarked on that journey. Here is results of 6 hours of integration, all in all it was quite a waste of time. But I confirmed that it doesn't make sense to shoot Ha with stock camera. It's NGC 7822.

Are you ready for a solar eclipse on Oct 14th? I am almost there here is my solar filter progress. Now it's just about connecting those two things into a single piece.

I was quite lucky this week, few nights with clear skies and I was able to complete 6 hours of IC1318 and NGC6888 aka Butterfly and Crescent Nebulas respectively. I think I finally nailed down whole process, it appears that on many subjects 6 hours is enough of the data for me to work with and get a descent pictures. Shot with Canon T3i, 135mm F/2.8 lens ISO 1600 and L-Enhance filter. I am still learning tricks around processing that data, this was a second try. #astrophography #astropic

Back in June I shot butterfly nebula, it was just 69 min, now starting new project with idea to collect at least 6 hours of data. Here is region of the sky I am shooting at.

Just finisher Cygnus Loop project. This is supernova remnant, it's believed that at the time of explosion it could have been seen from Earth in a broad daylight, so powerful it was. It's consist of West and East Veil nebulas and few other pieces. Sh2-103 Cygnus Loop/Veil Nebula shot with Canon T3i, 135 mm, F/2.8, ISO 1600, L-Enhance filter. It's about 6 hours of total integration time. I've used dark frames in that one and not entirely sure if I like it. #astropic

Starting new project, first draft of Cygnus Loop aka Sh2-103. L-Enhance filter turned out to be a savior from a Bortle 7-8 light pollution.

I have recently combined 4 and 2 hours integrations and got results which I am proud of. It's been a long journey with a lot of learning, I think I know what I am doing now, though there is still a lot to learn. Posting my "before" and "after" pictures, first one I took with 50mm lens last year and second with 135mm this year after learning journey and adding equipment, both pictures are from the same location, Bortle 7 sky. #astropic #astrophotography

I finally had clear skies and pulled 4 hours image of North America and Pelican Nebulas. Just a bit of processing. I am happy with over all results, I know I can learn bit more on processing side. Shot from Bortle 7 sky, with Canon T3i, 135mm, F/2.8, ISO 1600. #astropic
