Here is the Lagoon Nebula as recorded by an Askar FMA180 Pro lens (40mm, f/4.5) and a ZWO ASI678MC uncooled planetary camera. You should click on the preview to see the full image size and to read more details on the capture that appear in the captions.
This was a test to see if I could image in one-shot-color within the worst part of the light dome of my Bortle 7 skies. The light pollution in this area is bad enough that it's quite difficult to see any of the stars that make up the so-called Tea Pot asterism of Sagittarius. I normally wouldn't attempt an RGB image this low toward my southern horizon (the Orion Nebula being my previous limit) but with it being galaxy season this was one of the few targets that I could try using the small FMA180.
That star cluster toward the lower left is NGC 6544, a 7.8 magnitude globular cluster that is being seen through much of the dust and gas that surrounds the Lagoon Nebula (making the stars look quite red). It may be more than twice as distant as the Lagoon nebula itself.
Given these results and later this summer I may try this target again in bi-color Ha and OIII with my larger format ZWO ASI183MM Pro camera.
Image capture with SharpCap Pro, processing with PixInsight (calibration, registration, integration, Spectrophotometric color calibration, histogram adjustments, StarXTerminator, BlurXTerminator) and Photoshop 2023 (recombined starless and stars layers, tweaks, photo frame).
Thanks for looking.
