  1. 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! Equipment: CEM60 asi294mm quattro 10" Astrodon RGB/Ha
  2. 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 Equipment: CEM60 10" f/3.9 Newtonian asi533mm Astrodon 3nm SHO/RGB
  3. Thank you Very much, Kevin! It was a lonnng project but very fun to say the least 🙂
  4. 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!
  5. 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!
  6. 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
  7. Hello Folks! Messier 33 - 100 hrs (S2HaO3 / LRGB) In the photos above I have included several different edits and they are as follows. HOO / Lrgb HOO / rgb stars Standard Lrgb SHO / Lrgb SHO / rgb stars This 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: Cem60 10” F/3.9 Newtonian asi533mm Astrodon SHO/LRGB (3nm) Total exposure time: 100hrs
  8. Thank you! After imaging with a Newtonian for the past three years, my refractors have been collecting dust haha
  9. 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!
  10. 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.
  11. 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
  12. 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!
