Hello again everyone. I haven't posted here in a while. Clouds and work kinda got in the way. I also was building a little backyard observatory! It is a little 8' geodesic dome design that I made from scratch with foam, wire and stucco. I started building it last December, but I figured I'd better finish it up and I did a couple weeks ago.
I completed (so far anyway, these could always use more data), my first image from my new observatory!
It sure is nice to sit inside and image, especially in the biting winter winds. I started this image a few days ago, on a night that had 70+ m.p.h. gusts. In fact, just up the road at Carter Lake, they recorded a couple of gusts up over 100 m.p.h.!
No problem in my dome though. The wind didn't get inside at all and I was able to image 5 minute exposures with the stars staying nice and round. I am just a little pleased with my dome
.
Anyway, last night I was able to capture a little SII data on the Rosetta nebula to go with the Ha and OIII data I had before.
I only got 10 images at 300 seconds of SII before clouds rolled in, but I wanted to see how it all looked together. I will definitely be getting more data as this image is still too grainy.
The first is in the "Hubble Palette" where the Sulfur II is red, the Hydrogen Alpha is green and the Oxygen II is blue. The second is in HSO Palette, where the Hydrogen is red, the Sulfur is green and the Oxygen is blue.
