Thanks, Tom and Olly.

This is incredible! The detail of the stars and nebulae is outstanding. You should submit it for APOD.

This is a 20 hour LRGBHa exposure of The Fireworks Galaxy that I captured part from the end of July, and last two nights. I was able to pull out some of the dim dust around the Ghost Brush Cluster and some small galaxies. Some of the galaxies in the image: PGC 166192 - MAG 15.15, PGC 64824 - MAG 17.00. Exposures: L: 60x300s R, G, B: 40x300s each Ha: 50x360s Total~20 Hours ZWO 1600mm FSQ106 ED Questions / comments / processing advice much appreciated! Thanks for looking

Thanks, Ouroboros, Carole and Mars.

Thanks, Bob, Rodd and Emyliano! This has actually been on my list of targets for some time. I still want a close-up image of it with my C8...

I captured this beautiful nebula the last couple of days. I'm surprised that there are so few images of this one, as it seems a perfect target with the reflection nebula, star cluster, dark nebula, and faint galaxies behind the dust. I was able to pull out some faint nebulae in the background due to my ~30 hours of exposure. I was especially surprised by the interesting H-alpha region covering NGC 7142. Some of the galaxies I've found in this image are PGC 97261 - Mag 12.87, and PGC 168082 - Mag 13.52. FSQ 106 ED ASI 1600mm L: 72x300s RGB: 50x300s each H: 110x360s Total = 29.5 hours Questions and comments much appreciated! Hunter H-alpha channel:

Thanks, Mars.

I wouldn't be able to have a RGB image though... the individual channels are singe 30s. Also, the images aren't stacked, just color combined.

That's what I thought also. I'll have to do some observing when m31 is a bit higher. The Andromeda Galaxy is a great target for this challenge. Big and bright...

This is composed of a single 30s exposure unguided through each filter (RGB) to make a color image. The noise in this image was very difficult to deal with... but that's what happens when you don't stack🙃 For processing I did lots of noise reduction using TGV denoise, MML, and ADCNR in Pixinsight, stretch image, and curves transformation. Captured 29 July 2019 FSQ 106 ZWO1600 mm Hunter

Thanks! I'm definitely going to print this one. I'm glad you like it.

It looks a bit purple to me also. You can make it more blue by using a mask of the OIII and reducing the red saturation in it.

Beautiful color... especially the stars. It's interesting how there isn't more OIII though. I captured this image with 9 hours of OIII last year and it had quite a bit of OIII. Maybe you could stretch the Oxygen channel more?

Thanks, Frank, Olly, and jjosefsen, I'm glad you guys like it!

Here's with some green subtracted...

I managed to get a bit of exposure in between sunset and moonrise, so I decided to image M17. This image is only 2.4 hours of exposure and a 'rough' process of M17, but I'm happy with it as it's the first time I've imaged the Swan Nebula. No lum data yet... ASI1600mm FSQ106 Atlas Pro AZ-EQG ZWO RGB: 180sx16 each, 2.4 hours total. There seemed to be a large amount of green in/near the center. I'm not sure if the green is accurate... Questions/comments always welcome.

Thanks, Carole, Mars, and Alan. I'm thinking I will, but I'm now working on another image, so it might be a week or so...

Thanks! I also like the clouds and glow:) Thanks, Geof. I've found milky way astrophotography to be really rewarding. It's also fun in a dark sky because you don't have to bring the full setup to get some images! I think you'd be able to get some great images with the modified Canon and any lense less than 25mm would probably work. If you do get a widefield lense, the Tokina ATX 11-16 mm is great for Canon. And the Nikkor 14-24 is great for Nikon... Thanks

Thanks Stu, it was! Joshua Tree is now #2 on by best skies list, with only Yosemite above it.

Here's a revision:

I captured this image while out at Joshua Tree this month. Despite being quite hot and a setting moon, the sky was incredible. This was really the first time I've seen the core of the milky way from a very dark location, because the other times I've been in a good location, the core wasn't visible (wrong time of year or hidden by mountains+trees🙃). This is a 6-panel mosaic captured around midnight PST. There are some light domes near the horizon, along with green/red air glow and clouds. Jupiter and Saturn are visible in the image along with the summer triangle, M8, M20, M16, M17, NGC7000, IC1396, the Rho Ophiuchi Complex, and the Andromeda Galaxy. Equipment / exposure info: Nikon d810a, static tripod, Nikkor 14-24mm. f2.8 ISO3200. 6-30 second images stitched with Microsoft ICE. July 7 2019 ~12:00 PST. Hunter

Thanks Thanks.

As one of my favorite parts of the sky, I decided to to a mosaic of the Veil nebula. I may add two more panels to include NGC 6995, however, I decided to process what I have at the moment. FSQ 106 ASI1600mm Panel #1 and #2: ZWO Ha: 330s x 52 ZWO OIII: 330 x 70 This is a two panel mosaic (actually my second deep sky mosaic), stitched and processed in Microsoft ICE and Pixinsight. Visible in this image is the Witch's Broom Nebula, Pickering's Triangle, NGC 6979, and NGC 6974. I would like more annotations on the dimmer nebulae, but perhaps they do not have catalog numbers. Below is an annotated version: And a gray-scale image: I was quite surprised by the amount of OIII signal in NGC 6960, but I've never imaged it with narrow band before🤔 Thanks for looking and as always🙃 comments/ questions appreciated.

Hi all, this was taken 7th of July at Joshua Tree National Park CA. Nikon d810a Static tripod Nikkor 14-24mm f2.8 30 seconds ISO3200 f2.8 Processed in LR and Pixinsight (curves, saturation, brightness, vignetting correction). Thanks for looking.

Thanks, I believe the halos are from my ZWO filters...
