Day cruise to Kenai Fjords National Park, at some point we they started service "glacieritas" margaritas with ice from glacier. We saw whales and beautiful fjords. Listening to ice breaking into the ocean and seeing it is just priceless. 1/3
I had an opportunity to experience Eclipse, it's definitely breathtaking event. However all my plans were thwarted by clouds, on a positive side, though we saw few things. It all started with me, forgetting intervalometer since I typically use small computer to manage session and it sat in the box, but because of clouds I decided not to go back and just enjoy the show. Though I was able to take few shots and I can call it success. One has more of a corona and another prominence.
Here is my progress on latest #astrophotography project. I've done 2 panels 4h on Horse Head and 3h on Orion Nebula. Processed with #siril and stitched in #gimp. Problems, overexposed Orion Nebula, I need to shorten my exposures, then add more data on Horse Head and pick something else for stitching, something with more precise star alignment, thinking about ASTAP. #astropic
I've always been fascinated with Orion constellation, it's definitely my favorite. I remember last year when I was shooting Orion using my trusty Canon and saw a glimpse of Horse Head Nebula I was excited. It was not much even though I shot for hours. Fast forward year, here is about 1 hour shot through L-Enhance using astrocamera. You can clearly see all. It's start of a new project mosaic 4 or 6 panels, 6 hours each, I am not sure how to do it, so I am learning. #astropic
I've learned that 4 hours is a really weird spot, essentially it's really close to 2 hours in terms of the data I get, maybe less noisier, but I typically need at least 6 hours to get visible improvements comparing to 2 hours of data. Here is M45 aka Pleiades with 4 hours. #astropic #astrophotography
Entirely unplanned target from last night. Seven sisters aka M45 aka Pleiades. I was thinking about Orion, however it was too low i.e. obstructed and clouds was supposed to move in soon. So I saw M45 at zenith, changed course and here is result.
We finally had some break in clouds and I was able to spend goo amount of time my target. However I picked wrong one because that nebula has emission and reflection pieces and I was shooting through a filter, that cut reflection part. This is Flaming Star Nebula 1500 light years away from Earth along with Letter Y Star Cluster, Spider Nebula and Fly Nebula. Really quick processing. #astropic
Unscrew 4 screws to get access. I think problem with it that they placed resistor which is too much for that battery and rest of the circuit, that what makes diode underneath this glass too dim(see red circle for resistor). What we need to do is to by pass it, see one of the blue lines, either one would work. My soldering skills aren't that great so I just soldered over resistor. WARNING it will void your warranty, do it at your own risk. That worked for me. Final result is in the picture.
Since I had no chance to see Geminids meteor shower due to clouds, I've decided to improve my polar scope illuminator. If you bought Sky-Watcher Star Adventurer 2i star tracker, pro package comes with polar scope illuminator which is too dim, at least for my Bortle 7 area it's absolutely useless. Someone may say it's just bad unit, but trust me there are lot's of ppl having the same problem, so it's probably flawed design. #astrophotography Here how it looks and solution below:
I call it project of learning, just for the fun I've decided to fully utilize my new gear. First night my focus shifted, then I've realized I forgot to turn on cooling, then I've spent time learning how to guide. Now I am guiding, focused using HFR tool in Ekos/Kstars, but I am suspecting that SWSA running out of batteries. It's been fun, here is 4h of leftovers(about 50%) on NGC281 aka PacMan #astropic
We had Moon's halo a couple days ago, it's an incredible and breathtaking experience. I chose to enjoy it rather than set up my gear to take a picture, however I took a photo with my phone, quality is meh, Moon is overexposed, but you get an idea. So it's more like a historical evidence.

First light with a new toy. Real astrocamera ASI 533MC Pro, it's way ahead of my old trusted Canon. I am still learning and building my workflow with it. I've setup yesterday to workout focusing with it, it's way harder since you view your picture through VNC screen :D. Here is first light, Orion Nebula and glimpse of Horse Head Nebula, just 15 min of integration, no calibration frames no framing, quick processing, but I love it. #astropic
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
