Just some more reprocessing of last year's data. This is the Sadr region with some of the Butterfly Nebula and the Crescent nebula. I'm looking forward to this coming back around this Summer for a larger mosaic of the area.

Galaxy season can be a little boring when you don't have a setup suitable for small wonders... So I'm going over OLD data to see what I can pull out of it. This is a starless version of only 51 minutes on the Lagoon Nebula from 2 years ago, using a $150 telescope and a 13 year old mount.

If you're already using a multi-narrowband filter and a color camera, this palette configuration makes for a great false SHO look. I've found that with the Radian Triad Ultra quadband I can be a bit more inventive with color in Photoshop as it seems to have some separation between Red and Magenta and HA & SII. It's very subtle, but it's there and makes for a more dynamic image.

Going back through data with using PI and PS. This is the Soul Nebula with about 5 hours of data from last fall. As a die-hard Photoshoper, I can admit that you really need to use both to get the most out of your data. That said, there's nothing wrong with starting out in Photoshop. PI is just about the least intuitive piece of software available for public consumption!

The Spaghetti Nebula (Sh2-240) is deceptive! There are bright spots and dim spots. After seeing the individual frames, I thought I had much more data in the end than I actually did. I scrapped processing this 10 hours of data 5 times before settling on this image that I'm still not completely happy with. It'll be dipping behind the trees early in the evening soon, so that's it for this year. Maybe next year I can do this one with mono camera??

About the Site

Katorella is a mashup of my daughters names that I had originally made up for a bike that I never built. They adopted the name, but I stole it back for my astronomy endeavors.

I’ve been casually into Astronomy for decades, but more recently I’ve taken a serious interest. I’ve been really imaging since 2017 from just outside Chicago, which creates challenge after challenge. I want to prove that you can do this from anywhere without spending your whole life’s savings.

I believe that anyone who wants to make their own art from hidden treasures in the sky should be able to go for it!
