I live under fairly light polluted skies. I don't get a chance to get to dark skies often enough for my tastes between what I call the WWF factor (Work, Weather, Family).
My main set up is a Losmandy G-11, Pentax K-1 and a variety of lenses and telescopes. I recently picked up a Whitecat 51, and while I love it, it's useless in my backyard. I've got an OIII filter and I decided to see how it would work with the K-1 and Whitecat.
Below are Mono versions (about 20 min total each) since the OIII filter on a DSLR gives a weird green color that I can't reconvert to normal coloration.
I shot the Veil Nebula and it's the first time I was able to capture the whole thing. I obviously need more time on the Veil, but so fat I'm impressed with the combination of the Whitecat and K-1. I've got an Optolong L-Enhance filter on it's way to me. this looks like it might be the solution to my issues.
The Lagoon and Trifid were nice and bright, and I can't wait to reshoot these in color from a dark site. I was amazed at how large the Lagoon really is. When I was shooting it, it was just above the trees in my back yard. , and if it was as close as Orion is, it would be far brighter than the Orion Nebula is. The green shot is single 100sec. frame through the OIII filter the tree tops are the blurry things at the bottom. You can see how big and bright the nebula is.
