Nice sketches and an interesting discussion about filters... Here is a sketch of NGC40 made last year at x300 (without filter) with a 12" dobson. Looks almost the same than your sketch at x330, but I didn't catch the oval form.

Excellent study and as always outstanding sketches. Having seen this recently I find I'm in a quandary to either slow down my Herschel observations or get through them and go back . . . There are many items I would like to sketch like NGC 663 (that would be an interesting study to compare 663 to M103 as I think 663 holds up well to M103) but I found I felt rushed in doing even a rough sketch so that I could get through the items for last night. Anyway, again nicely done for the fact you have me rethinking my approach to my own observing right now.

I keep some of the major lists active, but I don't work that hard at completing them. In fact, I don't even have all the Messiers logged (85 out of 110), and the H400 can be downright tedious in places (I currently have 167 out of 400).

An excellent series of observations of NGC 40 at different magnifications showing more detail within the planetary nebula. Thank you for sharing them with us all.
Jef- An excellent observation of NGC 40 as well. A very interesting planetary nebula.
