Hey Folks!
First and foremost, I hope everyone is having a happy holiday season
Today I wanted to share with you all a quick project that I was able to finish up between work and clouds and life. The Tadpole Nebula - This is one that I have always wanted to image but has evaded me for quite some time but I was finally able to put some hours into it. This image consists of 30 total hrs of data (24hrs of SHO and 6hrs RGB for the stars).
My goal in these SHO/RGB images is to create a somewhat ethereal/realistic version using narrowband data. Imaging these targets using LRGB filters is the ultimate way to achieve this result but my light pollution is just too poor for that. For this image I overlayed the SHO data with the aggressively stretched RGB data. The red in the nebula from the RGB data cuts through the narrowband data and really gives it a unique looks which I have grown to really strive for lately. I'm glad that I'm able to replicate these results finally.
That all being said, I hope you all enjoy

Absolutely stunning. You put those 100 hours to fantastic use. The second image (HOO rgb stars) had my jaw on the floor!! And it just got better as I scrolled down!
Thank you Very much, Kevin! It was a lonnng project but very fun to say the least 🙂

Hi Stu.. I did get this mailed to APOD but who knows how long it will take them to respond. I've sent multiple photos over without a response so my hopes are not high!

Astonishing set of images and level of dedication to get to 100 hrs on a single target. Congrats!
My personal favourite is the 1st, but having never seen M33 shot in SHO before i have to admit the last one is doing it's best to woo me!
Thank you very much! I had to try something difference. II knew that M33 had some incredible Ha regions so why not Oiii and Sii regions as well. Made sense to try!

Insane!
An outstanding rendition, and not so commonly done either!
That last image in particular is just fantastic!
Thank you very much! I look at them now and it seems like I pushed the data just a tad over the line.. not typically my style but when processing it I really just wanted to bring out as much as I could! The last image is my favorite as well. I did NOT expect that much signal to come from the galaxy at all. A very pleasant surprise! haha

Hello Folks!
Messier 33 - 100 hrs (S2HaO3 / LRGB)In the photos above I have included several different edits and they are as follows.HOO / LrgbHOO / rgb stars
Standard Lrgb
SHO / LrgbSHO / rgb starsThis image has been a work in progress for nearly a month but I am FINALLY FINISHED.. although I'll probably edit these again and again and again until I'm 100% satisfied, lol. The months of September and October were extremely kind to me in regards to clear skies. My main goal here was to invest ample time to bring out the nebulae within another galaxy. In this case.. M33, the Triangulum Galaxy.The active regions in this galaxy are abundant so what better way to capture them than with 3nm SHO filters? It was definitely an endeavor I was unsure of until I started capturing sii data.. Which there was plenty of.In addition to the narrowband data, I have never had the chance to capture this using standard broadband filters either. I live in bortle 7 skies so this target was never really on my list considering its low surface brightness. I need the LRGB data to combine with my SHO data to achieve the look I wanted so I thought “What the hell, let's get a full LRGB data set as well. 15hrs were invested into Lum data and 10hrs were invested into the RGB data. More data here would help but dark skies would ultimately be the cure for the issues I ran into with broadband filters.As far as the narrowband data goes, I collected 25hrs of each to be sure I was capturing enough to bring out the fainter bits of nebulosity in m33. This was actually a good amount and was so much fun to work with.This is my largest project to date and I really hope you enjoy it!--------------------------------------Equipment:Cem6010” F/3.9 Newtonian asi533mmAstrodon SHO/LRGB (3nm)Total exposure time: 100hrs-

Love this. The level of detail is insane. The resolution of the big scope being put to good use here. Very nice processing too. Great work!
Thank you! After imaging with a Newtonian for the past three years, my refractors have been collecting dust haha

FAKE!! 🤣 kidding, i mean its so beautifully done it looks pained or rendered, this is absolutely gorgeous. I'm not an imager but I can say I haven't seen this sort of contrast and detail before, amazing.
HA! I'm sure some think its fake. I know this isnt the most NATURAL looking image of course.. but Thank you for the kind words!

Spectacular image! The 533mm working really well here. Not sure you needed 600s subs though at F3.9, what gain did you use?
Thank you! I was shooting at unity here.. I really just default to 600s subs regardless of scope to be honest haha. Seems to work well and my 600s subs have always looked a bit smoother than my 300s subs.

Would you be able to provide some insight into your denoise workflow?
I used topaz as well as photoshop to denoise (not sharpen) the starless HOO image.. then I proceeded to add stars. If I would have been able to capture the amount of data that I wanted to capture, I likely wouldnt have run a denoise process

Greetings!
I spent most of last month imaging the Witch's Broom Nebula through my 10" Newtonian. The filaments are simply incredible. The tough thing about this target is getting enough data. The Oiii and Ha both have separate structures so you cant just use the HA as luminance and your OIII and Sii as color data.. with emissio nebulae, one would just achieve good color with all three channels first and then overlay it with their Ha data to create a nice, clean image to hide the 2hrs of Oiii and Sii data haha! This was not the case.
I was only able to grab about 7-8 hrs per channel (Ha / Oiii) which is half of what I would have liked to capture. I did grab 1hr each for RGB stars using 30s sub exposures.. These turned out to be a nice touch. Nothing better, in my opinion, than RGB stars with some Ha and Oiii data!
I hope you all enjoy!

Hey Folks!!
This dark nebula lies near the star Sadr. A very active region, home to several of our favorite targets to image! This has always been one of my favorite targets but it has evaded me for the past two years. I'm happy I was finally able to put some decent time into it. In the past I had never left the green tones from the HA data in my SHO images. To be frank I used to be highly against any greens in my image.. As of late, that hasn't been the case and I quite enjoy it now. A tasteful touch adds a lot to an image I suppose. Funny how opinions of imaging style and preference start to change over the years...
I hope you all enjoy!

This image has me looking at this nebula in a totally new light, beautifully done. I like how you didn't completely zap all the green too, it allows some subtle but very pleasing transitions in the colour tones. Detail is spectacular too.
Thank you very much! I had so much fun processing this one and will likely be the method I use for other data sets. I am always flip flopping about keeping or discarding the green hues in my images.. 9/10 times I just like having them.. otherwise I should have shot a bicolor data set haha. The greens add a whole different dimension.
Cheers! -

bloody lovely that is!
8 clear nights in a row? I wouldn't know what to do with myself if that happened over here, haha, I'm lucky to get a few hours at most!
Not a common occurrence for the midwest, thats for sure

I can’t believe the detail. One of best images I’ve seen regardless of subject.
Different weather here across the Atlantic. Haven’t had a decent clear spell for some time
Thank you very much! I dont suspect that I will have a streak like this for some time. Gotta take advantage when they pop up!

Hello!
I hope everyone has been having a great week. I know I have with all of these clear skies... whoduh thought... In fact... I was able to image for 8 nights in a row which is rathe rare for the Cincinnati / tri-state area!
There were good nights and there were bad nights. I spent the first 4 nights collecting Narrowband data on the Pac-Man Nebula. This all went smoothly, and I was able to gather about 30hrs of data which I reduced to about 20 or so (a good guess, I haven't actually checked how much data is included in this photo below). The following 3-4 nights I spent collecting LRGB data as I was curious to see how an LRGB data set of an emission nebula would look from bortle 6/7 skies. I was hoping to grab another 25 hours or so... but alas... I had adjusted my camera settings for my narrowband flats and forgot to change them back to shoot LRGB. I spent the final two nights recollecting my data using the right settings and my goal at this point was to simply grab RGB data for natural star color.
Post processing this dataset was tricky. My sii data suffered from mottling due to the imperfections of the 294mm's sensor. This was a real pain to process out. My ha data looked clean as did my Oiii which was a relief. I managed to collect 8hrs of Sii/Oiii and 14hrs of HA. I was entirely unsure how to approach this data set. I wanted to produce something unique. Something a bit different than my standard SHO colored mages. It started off rough, but I was able to reach a result that I am more than happy with.
I think this is to date, one of my better photos! I spent a lot of time carefully sharpening the incredibly bok globules within NGC 281. This nebula has so much dimension and depth that I felt that not demonstrating this through my image would be sacrilege.
All that being said, I hope you guys enjoy!

Hi Folks!
I wanted to share with you all my photo of a dark nebula in Cygnus! I did collect a full narrowband data set but I really enjoyed the HaRGB version due its more natural color. This would have ultimately looked best with just LRGB filters but my skies are simply too bright. I tried a new (and very odd) way of adding in my Ha data.. and it actually worked. I've always avoided HaRGB composites because of difficulty integrating my Ha data.
I hope you all enjoy!
