Here is a wide field image (I wish it was slightly wider) of some more or less well known nebulae in Cassiopeia, I am not sure if the rather faint Abell 85 (LBN576) has a popular name but the two Sharpless objects are known as the Little Rosette Nebula (Sh2-170) and The Phantom of the Opera Nebula (Sh2-173).

This is a two-panel mosaic taken with my dual RASA rig on Chrismas day (one panel before and one panel after midnight). The moon was partly up but the NBZ filter handled that quite well. To Sh2-170 and Sh2-173 I have added about 50% refractor data that I took about a year ago.

So, captured 25-26 Dec with two RASA 8 equipped with ASI2600MC on a Mesu 200 mount. 164 x 5 min with IDAS NBZ dual band filter, so nearly 14 hours (not counting the Esprit 150 and 100 data added locally).

Cheers, Göran
