identified the field

Helped Risa recognise the field of view in the Andromeda galaxy she had imaged. She wanted to know if she was seeing the galactic arm.

Short answer: yes.

Remind her that with her 8" SCT, she was at high magnification! Tight on the galaxy centre and M32. I estimated the field to be less than 40 by 25 arc minutes. Only getting a fraction of the entire galaxy. Also was seeing stars down to magnitude 15 and 16!

Sent her some charts from SkyTools.
