Veil Mosaic

This is my first mosaic. It is really hard to get the backgrounds the same. This was a lot work. This is with my new ZWO CMOS OSC camera.

I had plans to do a similar 4-panel mosaic with my ZWO ASI2600MC Pro camera, but decided to start with 2-panel mosaics in Pixinsight before tackling such an ambitious project. Nice work! One comment.... The background is a bit bright for my taste. Opening the image in Photoshop, I saw there's a fairly wide space on the black end of the Levels histogram. I increased the levels black point by 25 ticks, and the background became much darker without losing much, if any, of the faint nebulosity. Again, it all depends on personal preferences. -- Mike Mike Dodd Louisa County, Virginia USA http://astronomy.mdodd.com |

Thanks. I played with that and it does eliminate the overall brightness of some of the nebulosity. Calibrated monitors still vary some so we may not be seeing it the same.

Hello Robert I really like your mosaic. Well done. It's on my bucket list to do one day! Like Mike, I took the libedrty of downloading and playing with your image in Photoshop. I tried posting the resulting image to my album in the group photos section but the image ended up looking quite blurry and washed out. Not sure what Groups.io is doing with photos. Attached is my version. Let me know what you think. Don Anderson

Thanks Don. I see you applied more min filter to reduce the stars and darkened the background. While it made the nebulosity jump more I look at a balance of highlighting the object and trying to make it still look natural in the sky. I applied about 6 or 7 - 1 pixel min applications that I reduced each to 20 % to get the reduction of stars that I got. I tried more and decided to stop where I did. Every person has a very different philosophy of what they like. I wish I had gotten more exposures for each panel but I am pleasantly surprised what I got with 2 hours each. I really like the CMOS cameras sensitivity and think I want to try more mosaics. They are so easy to stitch in Photoshop. If I get some imaging time this winter i may try an Orion mosaic.

Yes I did tweek it(levels, curves, Noel Carboni action make stars smaller, brightness/contrast and finally unsharp mask) to give the nebulosity more punch. I tend to do that even with my terrestrial photography. Just another interpretation. Anyway, those ZWO CMOS cameras are really good performers. My rig is a Tele Vue NP127is, Starlight Xpress SXVR-694 mono, SX filter wheel, Lodestar X2 guider on a Borg 50mm guide scope all mounted AP900GOTO CP3. I live in a large city with lots of light pollution so I'm only able to shoot narrow band unless I'm willing to drive long distances. Keep up the good work. looking forward to seeing an Orion mosaic.

I am glad you mentioned the astronomy tools. I forgot I had them already and have not used them for years. I am going to play with them. I live in large city light pollution also. My dark sky site is 3.5 hours away.

Ok, so I took your comments to heart and modified it. I had actually combined parts of 3 versions to make this one. So I made a new version and brought in the nebulosity from the original version to keep the brightness of the nebulosity. I love “painting” in PS. I had forgotten about the star color action and the benefits of unsharp mask. I used to use these and for some reason stopped. I also darkened the background and used the clone stamp tool some more to further fix the panel differences.

Robert. That's the ticket! your latest version really brings out the detail in the nebulosity especially in both the Eastern Veil and Witches Broom. I like how you have controlled the brightness of the bright star 52 Cygni in the Western Veil. I have shot that in tri color narrow band and end up with some filter reflections on that star. Have you tried the Crescent nebula yet? Don Anderson

Thanks Don. I have shot the Crescent a few times and always have trouble with it. It needs a lot of exposure and I have never given it near enough time. All my images are on the following:

Yes, the Crescent is quite faint. I like the Ha version the best. Will try it myself when I get some clear skies and warmer weather here in Calgary. Don Anderson
