Rosette Ha - TSA 120

Reading Peter's thread, it sounds like there were a few people imaging the sky from their backyards in Adelaide last night. Very gusty conditions here and I ended up with overly large stars I tried reducing in processing.

11 x 15 mins

I used a Tak reducer to bring the scope down to f/5.6 but it's a bit of a tight fit in the frame. The reducer has an extension ring you can attach that's supposed to reduce the image scale a little further and still maintain a well-corrected 50mm field, so will have to try this next time.
