Demelza,

Nice to have you back. Excellent rendering of NGC 457 and it looks like you picked the correct magnification too. It just fits your field of view. :bow: :cool:

Frank :)

Demelza,

I really enjoy your sketch of NGC 457. It has captured the image for me that I remember. You've made me want to view it with my 21mm and my 13mm Stratus with their 68 degree FOV. Last time I saw and sketched it was with a 25mm plossl.

Thank you! :)

The past few months the weather was a disaster. I'm glad that I could observe and sketch again last weekend.

The ET cluster is a nice open cluster. Not only for observing, but its also a nice sketch target.
