Fun with my new STC Duo filter
Here's two images I got earlier in the week with my new STC Duo filter. I've been relunctant (stubborn, too cheap) to go mono/narrowband, so I got one of these. It has 10nm bandpass at H-alpha and OIII - so can sort of do narrow band with an OSC camera.
Used it with my ASI071 OCS on an 8" F5 GSO. Processed as a colour images in PI. I put up Thor's Helmet in the 'other' imaging forum. And here's
Gabriela Mistral (just off Eta Carina). 65x 6min subs.
Tarantula. Only 27x 6min subs.
