From the album: Deep Sky Imaging
The Eagle nebula (M16/NGC6611) in the constellation Serpens imaged through narrowband filters using an 8" SCT (at the native 2032mm focal length), with a QHY268M camera. The Eagle Nebula is also known as the Star Queen Nebula and The Spire. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, the area which was made famous by the 1995 Hubble Space Telescope image known as as the "Pillars of Creation". The total exposure time of this image was 18 hours and 25 minutes. Exposures: SII:17x1200s, Hα:17x600s, OIII:17x900s, Hβ:17x1200s @ HCG:62/OFS:25 The color channel assignments are SII, HAlpha and OIII as RGB, and the HAlpha, OIII and HBeta (as RGB) used for the star colors.© Mariusz Goralski

My latest image of the Eagle nebula (M16/NGC6611) in the constellation Serpens, this time imaged through narrowband filters using my 8" Celectron SCT, at F10 - 2032mm focal length, with my astromodded and active peltier cooled Canon 40D DSLR. The color channels are SII, HAlpha and OIII as RGB, and color balanced to remove the heavy green color cast created by the strong Hydrogen Alpha signal. The total exposure time spent on this image was 20 hours and 57 minutes consisting of the following subs exposures: RGB: 13x15s, 19x30s, 17x60s, 12x90s, 17x120s, 15x180s HII: 2x600s, 9x900s, 4x1200s OIII: 1x600s, 8x900s, 1x1200s, 11x1500s SII: 2x500s, 14x1800s All at ISO1600.© Mariusz Goralski

This image is a cropped and rotated version of the M16 image to emphasize the famous "Pillars of Creation" part of the nebula, made popular by the HST image of the same name. The color channels are SII, HAlpha and OIII as RGB, and color balanced to remove the heavy green color cast created by the strong Hydrogen Alpha signal. The total exposure time spent on this image was 20 hours and 57 minutes consisting of the following subs exposures: RGB: 13x15s, 19x30s, 17x60s, 12x90s, 17x120s, 15x180s HII: 2x600s, 9x900s, 4x1200s OIII: 1x600s, 8x900s, 1x1200s, 11x1500s SII: 2x500s, 14x1800s All at ISO1600.© Mariusz Goralski

On 7th August 2015 I setup the scope and started imaging the Cat's Paw nebula, when I checked on the system 30 minutes later I was DISSAPONTED to find that clouds rolled in... I waited for the clouds to clear but no luck... While I was waiting for the clouds to clear before packing up I decided to reprocess my M16 data that I captured across 7 nights in June and July. Here are the reprocessed images... I'm quite happy with these seeing that the data was captured through Baader Ha, SII and OIII filters on a full spectrum modded uncooled Canon 40D, nights are quite cool tho, about the 6 degree C mark so I guess that helped. I concentrated on lowering the amount of purple halos around stars and attempted to preserve maximum detail, the purple halos are still there but not as severe as in the first version. I still have a bit of noise/grain in these images, but when I ran the noise reduction filter I started to lose detail, and the level adjustment that the detail wasn't effected too much the amount of noise reduction was not worth changing. I think this was the best balance between noise and detail.© Mariusz Goralski

Imaged F10 on a 8" SCT. OIII and the SII data was very dim and I had to push it more to bring out some nebulosity in that spectrum increasing the noise... Hence the purple halos on the NB image. I'll reprocess the narrowband image and attempt to remove the purple by tightening stars in the SII and OIII channels. Image tech specs.... H-alpha: ISO400 7 x 1800s Subs 7 x 900s Subs SII: ISO800 12 x 1800s subs 4 x 2700s subs 5 x 2160s subs OIII: ISO640 4 x 1800s subs 6 x 2100s subs 5 x 1500s subs RGB: ISO400 9 x 630s subs 7 x 350s subs 10 x 150s subs Data captured across 7 nights in June and July 2015.© Mariusz Goralski

Hello all, This is my latest image of the Eagle nebula (M16/NGC6611) in the constellation Serpens, this time imaged through narrowband filters using my 8" Celectron SCT, at F10 - 2032mm focal length, with my astromodded and active cooled Canon 40D DSLR. The second image is a cropped and rotated version to emphasize the famous "Pillars of Creation" part of the nebula, made popular by the HST image of the same name. The color channels are SII, HAlpha and OIII as RGB, and color balanced to remove the heavy green color cast created by the strong Hydrogen Alpha signal. The total exposure time spent on this image was 20 hours and 57 minutes consisting of the following subs exposures: RGB: 13x15s, 19x30s, 17x60s, 12x90s, 17x120s, 15x180s HII: 2x600s, 9x900s, 4x1200s OIII: 1x600s, 8x900s, 1x1200s, 11x1500s SII: 2x500s, 14x1800s All at ISO1600. Clear Skies, MG

HI All, Sharing with you my latest image that I processed so far. This is the Eagle nebula (M16/NGC6611) in the constellation Serpens imaged through narrowband filters using an 8" SCT (at the native 2032mm focal length), with a QHY268M camera o a hypertuned CGEM mount. The total exposure time of this image was 18 hours and 25 minutes. Exposures: SII:17x1200s, Hα:17x600s, OIII:17x900s, Hβ:17x1200s @ BIN2x2/HCG:62/Offset:25 The color channel assignments are SII, HAlpha and OIII as RGB, and the HAlpha, OIII and HBeta (as RGB) used for the star colors. Clear Skies, Mariusz

Hello Astronomers, I got the Topaz Labs Detail and DeNoise PS plugins and I have to say that they are great... noise is literally seek and destroyed without effecting the detail.... After playing with it for a couple of days I say that the plugins are definitely definitely worth getting. I reprocessed my M16 data from July this year and used topaz detail and denoise to try to get some more detail... I also applied the denoise filter to a JPEG image of the horsehead nebula from last year and, well I think the results speak for them selves. Clear skies, MG

Hi everyone, As I setup and started imaging the Cat's Paw nebula, when I checked on the system 30 minutes later I was DISSAPONTED to find that clouds rolled in... I waited for the clouds to clear but no luck... While I was waiting for the clouds to clear before packing up I decided to reprocess my M16 data that I captured across 7 nights in June and July. Here are the reprocessed images... I'm quite happy with these seeing that the data was captured through Baader Ha, SII and OIII filters on a full spectrum modded uncooled Canon 40D, nights are quite cool tho, about the 6 degree C mark so I guess that helped. I concentrated on lowering the amount of purple halos around stars and attempted to preserve maximum detail, the purple halos are still there but not as severe as in the first version. I still have a bit of noise/grain in these images, but when I ran the noise reduction filter I started to lose detail, and the level adjustment that the detail wasn't effected too much the amount of noise reduction was not worth changing. I think this was the best balance between noise and detail. I have AstraImage and it's great, but I heard that Topaz Labs Denoise is a good noise removal algorithm... Has any one used it, if so how does it compare to the likes of MoiseWare Pro, Astra Image and photoshop? Clear skies...

Hi All, Just sharing my latest image... this time it is the M16... I imaged this at F10 on my 8" SCT hoping that with the higher magnification I would get more detail in the pillars of creation... it's better then the one I've taken about 2 years ago using a f6.3 FR but it didn't come out as well as I hoped it would, the OIII and the SII data seemed to be very dim, so I had to push it more to bring out some nebulosity in that spectrum increasing the noise... I'm starting to think I'm reaching the limits of my modded 40D since my deep sky image quality seems to have stagnated... at least in narrow-band imaging. Personally I prefer the look of the natural RGB image, even though the narrow-band data acquisition was much longer. Image tech specs.... H-alpha: ISO400 7 x 1800s Subs 7 x 900s Subs SII: ISO800 12 x 1800s subs 4 x 2700s subs 5 x 2160s subs OIII: ISO640 4 x 1800s subs 6 x 2100s subs 5 x 1500s subs RGB: ISO400 9 x 630s subs 7 x 350s subs 10 x 150s subs Data captured across 7 nights in June and July 2015. Thanks for looking... Criticism welcome... please be gentle...

Another gift of a night for us here on the Central West Coast so I didn't waste it. Against the forecast of bad seeing and cloud cover I was treated to pretty steady skies so I jumped at another chance. I had learned quite a bit from shooting the Trifid nebula the night before as to what the rig needed so I shortened the spacing on the corrector lens ( bye bye rotator) and re-shot my flats into the sky at dusk with a white t-shirt wrapped over the end of the scope. As soon as Mars was into view and the sky dark enough I slewed to it, slightly de-focused and re-collimated the C8. Gotta love Bob's Knobs! Ok with that done I refocused and waited for the real Dark to set in.. Around 11p.m. I calibrated and tested the tracking accuracy of PHD2 and focus using tiny M9. 5 minutes was working but to play it safe I decided to go with 3 minute subs and after a bit of tweeking was ready for my real objective for the night... The Pillars of Creation have always fascinated me ever since the stunning Hubble images brought it so close to us and scientists finally had an understanding of what exactly was going on in this beautiful and amazing area of our sky. After that and since getting into AP it's been a goal of mine for quite a few years now. After imaging for over 3 hours total here are the results using my un-modded Canon and humble late 90's USA made Celestron C8. 35-180 second lights @ ISO 800 20 darks and 45 flats stacked and initially tweeked in DSS then into PS for WB and levels and curves and finally into LR for some slight tweeking and final sharpening. Please give me your thoughts on the processing and final image. Hope you get to capture your dreams as well every night...Look up!
