A further edit. I think I like this version better. I got rid of some of the weird coloring.

L: 48 x 300 seconds
R: 61 x 300 seconds
G: 82 x 300 second
B: 72 x 300 seconds
Acquired using NINA

This is my current project, the Iris Nebula. I end up with about 23 hours of data over 4 nights. #astrophotography

I use a Celestron EdgeHD 800, with a 0.7x reducer. I use a ZWO ASI 2600MM Pro camera with Antlia filters. Bottle 7 skies. Thanks for the compliment!

This is my current project, the Iris Nebula. So far I have 4 hours luminance, 6 hours red, and 7 hours green data. Just for kicks I used the luminance data in place of the blue channel and this is the result. Hopefully I'll get blue data this evening. #astrophotography

Comet Lemmon last night using my Celestron EdgeHD 800 with reducer. This is 12 30-second exposures in R, G, and B Antlia filters. Acquired with NINA. Processed in Pixinsight and Photoshop. #astrophotography

Technical Details:

Telescope: EdgeHD 800, 0.7x reducer
Camera: ZWO ASI 2600 MM Pro
Filters: Antlia RGB
24 x 300 seconds in each filter
Acquired using NINA

I took some narrowband images as well, but ended up just using the red master as luminance for detail.

I took this image a couple of nights ago. The bright star near the bottom left is called the Garnet Star. It is a red super giant, 4th magnitude, easily visible to the naked eye under good seeing. This area of the sky is located in the constellation Cepheus. #astrophotography

Technical Details:

Telescope: EdgeHD 800, 0.7x reducer
Camera: ZWO ASI 2600 MM Pro
Filters: Antlia 3nm HA, SII, and OIII
Approximately 2 hours of 5 minute exposures per filter

This is last night's observation. This is NGC 7822 an emission nebula in the constellation Cepheus. #astrophotography

Technical Details:

This is last night’s observation. This is called the Cygnus Wall, a 20 light year long ridge of gas and dust where star formation is occurring. #astrophotography

Technical Details:
Telescope: EdgeHD 800, 0.7x reducer

This was last night’s observation, the Elephant Trunk nebula. #astrophotography

I took the first picture last fall. It’s a mosaic of 4 panels of the Andromeda Galaxy. I never liked the gradient issue on the right side and was never able to get rid of it. Just for kicks I asked ChatGPT to get rid of it and the 2nd picture is the result.

Now I see buffalo as well!

Technical Details:

Telescope: EdgeHD 800, 0.7x reducer

This was last night's observation. This is a closeup of a portion of the Pelican Nebula This is just shy of 6 hours of data. #astrophotography

Last night’s observation, the Eagle Nebula.

I think I am already signed up with them. I always forget to add tags.

This is last night's observation, the Crescent Nebula, NGC 6888. An emission nebula about 5000 light years from Earth.

One of my favorite targets. Nice job!

This is a 2 panel mosaic of the Lagoon Nebula. Taken with my Celestron EdgeHD 800 and Antlia Ha, SII, and OIII (all 3nm) filters.

With a 0.7x reducer. This image is also cropped

After about 2 months of clouds I was finally able to observe last night. This is the Trifid Nebula.

I reprocessed an old picture of the Horsehead Nebula. I don’t remember much about the details of the acquisition but this is an extreme crop to concentrate on the Horsehead, itself. This is RGB and HA. I used the HA as a luminance layer for detail.
