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.

Hello All, Sharing with you my natural color image of the Eagle nebula. This project is a WIP as I'm working on exposing narrowband to emulate the Hubble image of the Pillars of creation, but I assembled the 2 hours of 15, 30, 60, 120 and 180 second subs which I exposed through the UV/IR filter for the natural color stars to use in the narrowband image. This has been exposed through a Celestron 8" SCT at F10 with my modded and cooled Canon 40D, tracked on a CGEM and guided with PHD2. The Hardware control and subs aquisition was carried out by APT 3.63. CS MG

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© Mariusz Goralski

Observation 25-26 July 2017 Date: 25-26th July 2017 @ 19:50 – 2:30AEST Location: Backyard Equipment: 14” Skywatcher GOTO Dobsonian, Televue 31mm Nagler T5 , Televue 17mm Ethos, Televue 11mm Nagler T6, Televue 2X Powermate, Baader Neodymium, Baader Contrast Booster, Astronomik UHC filter. The first thing I noticed from the beginning is that there was more sky glow than I would like, it was quite obvious that the seeing won't be perfect. I keep hunting for maximum magnification and detail on planets so before observation I re-collimated the Dobsonian from scratch. This time I

Another try from the same night as M8, this time M16 Eagle Nebula in H-alpha, 7nm filter attached. It came out really nice I think.. Scope: Skywatcher EVOSTAR 80ED DS-Pro Mount: HEQ5Pro Camera: QHY168C Filter: Baader H-alpha 7nm Guiding camera: ZWO ASI120MC Guiding scope: Panagor 400mm 16x200s exposure/ 53min total at -10°C binning 1x1 Clear sky!

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

Here's my latest, hope you like it ! 17x 300s lights at ISO1600, darks, flats and bias, equipment as per sig, modded DSLR at prime focus, Pixinsight processing. I actually took this back in July, but had a frustrating gap in processing when my laptop broke and had to be sent to Germany for repair - I had all the raw files backed up, but not the interim processed files nor the calibration files. There's a bit of coma still showing on this, but I think I've managed to get my spacings right now for some later runs still in my processing queue. The Eagle Nebula (M16, NGC 6611) is a young open c

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

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 nar

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 gu

As processing skills improve its fun to go back and work again on last years subjects so this is my reworking of the Eagle Nebula taken August 2012 -

In the last few nights I was able to catch more data of M16. I got much better Ha data (better seeing) and also some OIII and SII data, that I had to stretch quite far). In the end I'm happy with the result (it's at only 20 degrees elevation here...). I did some quite extensive processing, also using star masks and the narrowband data to create natural color stars...

Eagle Nebula (M16) by glowingturnip, on Flickr The Eagle Nebula (M16) is a young open cluster of stars in the constellation Serpens. It contains several active star-forming gas and dust regions, including the famous "Pillars of Creation", photographed by the Hubble Space Telescope. It is part of a diffuse emission nebula, or H II region. This region of active current star formation is about 7000 light-years distant. The tower of gas that can be seen coming off the nebula is approximately 9.5 light-years or about 90 trillion kilometers long.15x 300s lights at ISO400, flats darks and bias, equi -
Here is one of the images which never really got off the ground last year. I started in July 2012 imaging the Eagle nebula. It is a difficult target, very low from here, and usually in the murk, and I only had opportunity to gather 9 x 20 mins in Ha for it with my C11Edge. However I had previously taken a much wider field picture of this area, and with the magic piece of software that is Registar, I have combined the old colour data with last years Ha data, which has been used here as a Luminance, not ideal, but better than the 3 hours of data never being used at all. So here's the mono Ha pic
