Hello again from down under... This is the second last object image that I have imaged during my clear and moon less nights I was lucky to have been graced with... When I was exposing The Eagle Nebula, I imaged it through all of my narrowband filters, S2, Ha, O3 and HBeta... The first image I processed was predominantly using the standard Hubble palette SHO method (with HBeta only used for star color), but a while ago I found that using a color configuration of Ha, O3 and Hb as RGB, actually delivers colors which are very close to natural looking... with the added benefit of cutting through light pollution, allowing much longer sub exposures than with broadband RGB and potentially capturing fainter matter with more contrast. This image was taken with a 8" SCT (at the native 2032mm focal length), with a QHY268M camera and tracked using a "hypertuned" CGEM mount. The total exposure time of this image was 12 hours and 45 minutes. Exposures: Hα:17x600s, OIII:17x900s, Hβ:17x1200s @ HCG:62/OFS:25 Clear Skies, Mariusz

The Eagle nebula (M16/NGC6611) in the constellation Serpens exposed through narrowband filters at Hα, OIII and Hβ wavelengths to emulate natural colors as those narrowband wavelengths are closely corresponding to the RGB wide band. This image was taken with a 8" SCT (at the native 2032mm focal length), with a QHY268M camera and tracked using a "hypertuned" CGEM mount. The total exposure time of this image was 12 hours and 45 minutes. Exposures: Hα:17x600s, OIII:17x900s, Hβ:17x1200s @ HCG:62/OFS:25 The color channel assignments are HAlpha, OIII and HBeta as RGB.© Mariusz Goralski

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

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

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....

I’m trying to find indication (shareable evidence) of when the first telescopic photo of the Pillars Of Creation was produced. Can anyone point me in the right direction?

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.

Here's my last one from my summer crop - it actually turned into a year-long project, I took the Ha in August 2017, the OIII in July this year and the SII in August. 10 each x900s Ha, OIII and SII, darks flats and bias, equipment as per sig, taken in southern Spain, PI processing. Just for fun, here's a side-by-side comparison of my Pillars of Creation vs Nasa's, can you guess which is which ? Ok, not much of a contest really, but then their telescope is a bit more expensive than mine is ! Quite interesting to have a close look though, there are a number of features in common that I have managed to pick up that aren't apparent at first glance. I'd be happy to receive feedback on what you think, feel free to be honest since I'm not quite sure how I feel about it, especially the colours. Comments and cc welcome. Hope you enjoy, Stuart [edited to fix Flickr link}
