This is an interesting object in Auriga, featuring the overall emission nebula
(IC 410), the associated star cluster (NGC 1893), and the famous "Tadpoles" star
forming region below/right of the center.
I figured out I had some gradients in the O3 I hadn't fully dealt with with that showed up in the outer areas of the frame. While I tried to deal with those, with some success, I decided that this close crop hid most of those issues and also represents the interesting central core area & the famous "tadpoles."
It's a "natural color" image consisting of about 12 hours total exposure from the back yard using narrowband filters to combat light pollution.
(Jan 2021) I have been working on IC410 over the last couple
weeks... Then today I spent longer than I'd care to say walking through
PixInsight & Keller's book to process the narrowband images captured. Final
processing here was in Photoshop; this is about 12 hours split between Ha and O3
in a "natural color" blend. Just for grins you can see if you like these better
than the 2007 image attached.
Current images with the ST-8300M camera & FSQ 85 (native).
Here's a hubble palette view of IC410. It represents further
processing learning in PixInsight and some Photoshop Tweaks.
This is 49 frames (split between 5 and 10 minute exposures) with the FSQ-85 and ST-8300M camera using an H-alpha filter. Jan 2021, compare with earlier version below.
This object has "The Tadpoles," a bright feature just about 1/4 from the top/center. The tadpoles are pointing down from this view but are difficult to see. See the tadpoles in this narrowband image on my ST-8300 page.
This image is a combination of 44 images taken on separate occasions. The main imaging session was the 3/2007 Davis Mountains trip.
Takahashi TOA 130 (a 5" APO refractor) and Canon EOS D20a.
Captured from my back yard: 8 frames exposed for 2 minutes each with a H-alpha filter. I hand selected these frames as I wasn't autoguiding when I took the new camera on a shakedown cruise. TOA 130 telescope with reducer. See my IC410 Page for more on the tadpoles and a full-color view.
