From Sh2-170 to Abell 85 in Cassiopeia


Recommended Posts

Cloudy over here so I take the opportunity to process data from last X-mas that I had not given enough attention. The rather faint SNR known as Abell 85, CTB 1 or LBN 576 has no popular name as far as I know but Sh2-170 near the bottom is known as the Little Rosette Nebula.

I am a bit excited about that nebulosity in the centre of the image. It has some of those curved Ha arcs that could indicate a SNR, but maybe someone knows better....

Equipment: Dual-RASA8 rig with ASI2600MC and IDAS NBZ (Ha+Oiii) filters, on the Mesu 200 in my home obsy. 122 x 5 min, so about 10 hours. Processed in PI and PS, including both StarXTerminator and Starnet2.

Cheers, Göran
