HOO: HSO: And then I did two with dramatic hue shifts from HSO, trying to get maximum differentiation between the three narrowband channels - quite please with the results Ha->orange/yellow, SII->green/cyan, OIII->violet: Ha->violet, SII->orange, OIII->green: 13 each of 900s Ha, Oiii and Sii, darks, flats and bias. Skywatcher 200PDS newt (200mm ap, 1000mm fl, f/5), Moravian G2-8300 mono CCD +CC, AZ-EQ6GT, QHY5L11C OAG guiding. Pixinsight. Hope you enjoy !

My first planetary nebula, M27/NGC-6853. I know there is some room for improvement, but the clouds rolled in. Very happy with this so far from my unmodified 1000D. Bring on the winter months -
From the album: Deep Sky III
This image consists mainly of Ha with a small amount of Lum also blended into the central region in order to to better resolve the stars. The corresponding LRGB image with an Ha blend in both the Red and Lum channels, can also be found in this album. It represents 5.5 hours integration time. -

For my second attempt on M27, I used my new Esprit 150/10micron GM1000HPS combination (the result of the first attempt is in my Deep Sky album). This image represents about 10 hours integration. From a processing perspective, I decided to blend the Ha into both the Lum and Red channels using an Adam Block technique that I learnt through his "cosmic canvas" tutorial videos. Since the Ha is very strong and would obliterate the RGB information I decided to only blend a small amount into the red channel. Since I was interested capturing the faint outer halo, I decided to raise the level in this particular region. I was reasonably happy with the result - you can just about make out the outer halo, star colours are reasonable and you can see some inner structure to the nebula. LIGHTS: L:9, R:10, G:8, B:7 x 600s. Ha: 8 x 1800s. DARKS: 30; FLATS:40, BIAS:100 -

The Dumbbell nebula (M27). Processed using DSS. Hardware details: Camera: Canon 600D. Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 40 x 3min at ISO 800, Darks: 20 x 3min 0 sec at ISO 800 (from dark library), Lights and darks separated by 30 sec intervals. Flats: 50 x 1/50s at ISO 800, Bias: 50 x 1/4000 at ISO 100 Date of capture 05/06/2016. Atmospheric transparency was good. Auto guiding was stable. I increased the saturation by 25% and manually aligned the colour channel histograms. I stretched the red colour histogram more than the green or blue to increase its contrast. The 600D is astro modded so does pick up H alpha in the red so the result is far better than the old D200. 2x drizzling was done on this stack.© D Elijah

M27 (Dumbbell Nebula). Processed using DSS. Hardware details: Camera: Nikon D200. Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 39 x 3min at ISO 800, Darks: 20 x 3min 20sec at ISO 800 (from dark library), Lights and darks separated by 30 sec intervals. Flats: 40 x 1/40s at ISO 800, Bias: 30 x 1/8000 at ISO 100 Date of capture 30/04/2016 & 08/05/2016. Increasing cloud stopped imaging after about 1 hour, some wind, seeing was reasonable. The second night was less cloudy but transparency was much worse. Guiding was not great in RA but fine in DEC, PA was ok - I think I might have knocked the scope at some point in the night. The second night gave better auto guiding. I increased the saturation by 25% and manually aligned the colour channel histograms. I stretched the red colour histogram more that green or blue to increase its contrast. This helped bring out some of the nobbled structure within the nebula. 2x drizzling was done on DSS.© D Elijah

Acquired in June 2015 whilst setting up my new obs. At the time, I couldn't figure out how to process the image, so the data had been been waiting for my PS skills to improve. In Dec 2015 I decided to have another attempt, however, this time I decided to try processing the star layer separately from the nebula. I also decided to change from using Maxim DL for the calibration and stacking to CCDstack2+, mainly because I've been impressed by the data rejection results of CCD stack. I also decided to separately stack the RGB channels from my OSC to see if this would improve matters. LIGHTS: 27 x 300s; DARKS: 30; BIAS: 100; FLATS: 40 all at -20C. -

First guided image taken with 250PDS / AZ-EQ6 GT setup. Canon 1100D Baader modified, PHD2, Astronomik CLS clip filter, 1 hour 6 minutes, just as a test. -
As the title mentions, I got my Az-Gti setup working in EQ mode with the ASIAIR and managed to get fairly well polar aligned and whipped the mount off to M27 to do get some data on an object I hadn't managed to get in my non Goto days with my SGP. Oh I also managed to get it guiding as well which is the first time I've managed that and looked like I was getting okay results from the graph in ASIAIR. Light: 30 x 120s (1 hour) Dark: 10 x 120s Bias: 30 Flat: 20 Equipment: Az-Gti (EQ Mode), Evoguide 50ed with EvoFF v2, Canon 600d (unmodified), Light Pollution Filter, Zwo 120MM Mini with Astro Essentials Guidescope, ASIAIR Pro Plus. I gave Affinity Photo a go to stack it and edit it, which is something I've not used before and I think I need a lot more practice with it but it was nice to be able to use my Mac to stack and edit the photos on without having to dig out the Windows setup.

Even before getting my hands on the Celestron C9.25 I started planning to shoot again the Dumbbell Nebula from dark skies this time. Said and done, at the AstROmania astrocamp this summer I shot 10h of Ha and 10h of OIII (and 2h of SII, but I didn't use them so far) to which I added 3x1h for each RGB from a decent dark place nearby home. The mount recently started to track worse and worse, but PHD + the new PEC kept things under control. I also had available around 30h of narrowband and 6h of RGB taken from home 2 years ago with the 200/1200 newtonian and all these were combined in a smaller amount with the new data. For the highlights I only used the crisper data I had available so I hope I didn't compromise too much on the details. The SCT or the reducer makes the stars a bit softer. Perhaps a new one should be considered... So, for a total of more than 50h, the Dumbbell Nebula, around 1"/px. Click on it for a better view or visit the astrobin link for full resolution and other acquisition details. Clear skies! Alex

Love this little nebula, always a joy to look at and always a frustration to photograph as it never seems to go well, with either gear failure or weather getting in the way every time I try!
