Hey Everyone I wanted to share with you my Pelican Nebula Reprocess along with my narrowband imaging process. I will be using PixInisght for this tutorial along with Photoshop, Starnet, and Topaz Denoise AI. I have used these in only one other image and found them to be pretty useful on narrowband data sets. Topaz has a free trail version if that is something you may be interested in trying. This software seems to becoming somewhat popular (controversially so), so I really wanted to give it a try and see what it was all about! Your own noise reduction processes can substitute this step in my video... which is what I normally do. as I prefer doing NR in PixInsight. I personally find that starnet is extremely useful but topaz is useful only in certain situations and I have only had luck using it a few times. It does create artifacts if you are not careful and small adjustments can really go a long way. Use at your own risk! This is a somewhat unconventional approach to noise reduction/sharpening but.. it can work.The link to the video can be found in my bio. I found that this is a pretty basic workflow and gave me good results with my narrowband data. We shall see how it works on the next dataset!For this dataset I collected 12 hrs of data on the Pelican Nebula through my 10" F/3.9 Quattro with my asi1600mm-p / Astrodon 3nm SHO filters. I have made some color tone changes to the photo below so it will not exactly compare in color to the one in the video but the processing was the same. This came down to a change in creative decision I hope you all enjoy and ultimately find this helpful!———————————————Basic processing workflow:• Stretch SHO data• Combine HA/SHO/OIII in pixelmath• Starnet Ha data and SHO combined image. (Be sure to save SHO image with the stars in it. We will use it later)upLoad starless HA image into topaz denoise and make appropriate adjustments. Save• Upload HA photo from topaz denoise back into Pixinsight• upload starnet SHO image to PinInsight• color correct SHO image• Use HA data and luminance layer over SHO image• Final color corrections. Save• Upload new image into PS and add stars.

Hey Everyone I was able to capture a full set of data on THREE targets this weekend. My Pelican Nebula turned out very well while my Wizard Nebula data (Posted below) turned out decent and my Cave Nebula data.. well.. we wont talk about that one The Wizard Nebula - This is a pretty standard SHO rendition of this object with no crazy colors or processing methods. I was only able to grab 3hrs each channel but I felt like I was able to bring out some good detail thanks to the 10” light bucket. Additionally, I wasnt shooting through a shroud of smoke this time. The skies were very still and I was guiding at .3 - .4 then entire weekend. I hope you all enjoy!

Thank you very much, Peter!

Thank you for the kind words, Steve,. Much appreciated!

Thank you very, very much!!

Thank you! Everything definitely came together well and in perfect timing. Very happy with these results

Hey Everyone- The Pelican Nebula - A Full SHO Rendition Full res: https://www.astrobin.com/full/f0vo2z/0/ It has been a long, long time since I have posted any photos or posts on here.. or any forum, really. Glad to be exploring some the works of art again. Anyway.. The smoke cleared this weekend and provided me with some excellent seeing conditions from Cincinnati. I’ve gathered about 12 total hours on this gorgeous emission nebula using my asi1600mm and 10” F/3.9 Newtonian. The area photographed is being sculpted by immense solar winds created from nearby stars and is truly a chaotic and evolving nebula It is a truly humbling sight to see dense pillars of gas, light years tall, pop up on your computer screen after a night of setting up. I may not have access to the dark skies that I used to but I will never, ever let that stop me from imaging the universe and the jaw dropping beauty that it beholds. I really hope you enjoy and would love to hear your thoughts and comments! Equipment: Cem60 10" f/3.9 Newtonian Asi1600mm-p Astrodon 3nm Ha/Oiii/Sii ZWO EAF

I’m oversampled yes but I am getting better results imaging at .49” than I am with my newt and asi1600 at .79”

Hey Everyone! Quick question for the techies (moreso than myself) I have two imaging scopes: -An 8" RC with 1625mm focal length. My resolution with my asi1600 is .49"/pixel. -My other imaging scope is a 10" F/3.9 Newtonian. With an ASI183mm, my pixel scale would also be .49"/pixel These two setups give me the exact same pixel scale but the setup with my F/3.9 Newtonian is quite faster. My question is, theoretically, will these two setups provide the same amount of resolution and detail? My RC brings a lot of detail to the table, but if I could purchase the asi183 and use it with my Newtonian and get the same amount of detail in a fraction of the time, that would be optimal. I use my asi1600 with both my RC and Newt and there is a noticeable difference in resolution given the 600mm Fl difference as there should be. I want to achieve the same amount of detail that my RC gives me but with my faster Newtonian. Thoughts?

Greetings! This one was a really fun one to shoot! I am overall happy with the color that I was able to bring out as well as the detail. I would really like to hit this with my RC if there is ever a "Next time". Anyways, I hope you all enjoy!

I ultimately look to get the most dynamic range out of my photos so gain zero is the way to do this. I live and image from low end bortle 4 so my 600s subs aren’t washed out at all. I could go 1200s subs I bet. I just don’t have a 1200s dark library!

Hi guys! So as of last night I have my final lum data collected and processed. This is a total of 19hrs using 10min subs I am currently gathering rgb data as I type this! Hopefully I can grab about two hours of each tonight... and then flats tomorrow morning! I hope you all enjoy!

Greetings! I wanted to share the start of my new project, The Needle Galaxy! This galaxy is one that has always interested me but I've always been invested in other projects so I have never actually gotten the chance to image it. . This is much larger than I was expecting. It really makes me want to get a new focuser for my RC and see what kind of detail I can bring out at at 1600mm FL. I plan on collecting 20hrs of luminance data and about 3 hrs each of RGB data totally 26-29hrs total. Equipment: Cem60 asi1600-mm 10" f/3.9 Newtonian Astrodon Lum 600s exposures gain 0 offset 10

That sounds like a great night out! I have to ask, What are you views in the 15" like compared to the ones in your 24.5"? Im curious about both planetary/lunar and deep sky. I bet Globular cluster look thee dimensional with that 24". I have a 14" And I love it.. I cant imagine a 24 inch dob! haha Clear Skies

Thank you very much!

Greetings! This last week i spent my time collecting data on Messier 101, The Pinwheel Galaxy! This is a cropped version. I may work on my wide-field but I found through editing that my flats were terrible due to thin clouds. I did NOT get great RGB data. Lots of gradients haha. Anyways, I spent 4 hrs each getting RGB data and tossed all of it besides the best 50 minutes each. That seemed to help a bit thought. My 8hrs of lum data turned out very nicely. I gathered 8hrs with my RC and18hrs of data with my newt I still have to process. This images includes the 8hrs of RC data. Im also finding that what this edit looks like on my computer looks nothing like it does on my phone.. which is disappointing as Im not sure which one to edit for lol. ANYWAYS, I'm pleased! Hope you all enjoy it! 8"RC and 10" F/3.9 CEM60 asi1600mm-p (Gain 0 offset 21, 600s LRGB) Astrodon LRGB Clear Skies

Thank you skipper!!

Thank you very much! The kind words are much appreciated! I love messier 78, it has always been one of my favorite reflection nebulae but man it was hard to process!

Thank you, Cara! This was taken in bortle 4-5 skies in Colorado

Thank you, Adam!

Greetings! I Finished a new project recently Messier 78 - A nebula I thoroughly enjoyed finishing. As in never processing again. I love the Nebula itself as it is an extremely fascinating object, but because my RGB data was so bad due to bad flats and darks, it made this image really hard to process...I pushed through though. This nebula is a beautiful reflection nebula amidst the vast hydrogen clouds of Orion. I gathered 16hrs of Lum data and 2hrs each of RGB. If I grabbed more RGB data I could really stretch the colors a tad more but overall, I’m relative happy with this one.

Greetings! So I received my new 10" f/3.9 imaging newtonian and let me tell you... WOW. The difference in signal between the Newt and my f/8 RC isnt even comparable. I have taken 5 images of the Orion Nebula since I started this hobby four years ago almost to the day. This issue is.. I have never spent more than 3 hours on the target! This past week I decided to dedicate a few nights to this subject and collect a good 15hrs of data which would have been equivalent to 60 hours with my RC ( which is 2 stops slower). The coma corrector works perfectly spaced at 55mm and the collimation out of the box just needed a bit of tweaking of the primary mirror. This Scope is a BEAST and it is heavy. Balancing the Newt on my CEM60 was a challenge but twisting my scope so that my camera and guidescope point down to the ground at the home position instead of to the side or towards the sky really helped. Since I am using a guidescope I am seeing a bit of flexure even at 300s subs so my plan is to get the spacers for my OAG and have that ready to use again here shortly.. Anyway! Here is the Orion Nebula in all it's glory. Equipment: Cem60 10" F/3.9 Newtonian ASI1600MM-c Astrodon LRGB 10 hrs Lum 1.5hrs RGB each Clear SkiesTeagan

Yeah I know how that feels. This project actually took about two weeks. Back in Ohio that would not have been the case

Thank you very much Danny! It’s funny how effort put forth is data acquisition makes processing effort lesser. Much lesser. Some simple deconvolution, and color correction was all I needed to do!

Hey guys! I posted my first rendition of this object last week but it was more of an HOO looking rendition rather than an SHO version. I preferred the look without the green hues coming from the HA data.. I did some practice with pixelmath and finally came up with an SHO version that I like. This is my first time actually playing with three narrowband channels so I hope you all like it!
