Hi,
this result is pretty noisy considering that
I normally use about 200 in a stack. This was only 38
useable frames. Gully breezes the last few nights have spoiled
an otherwise good few nights.
I have imaged this field for two successive nights.
At first I thought IC 2913 was maybe a comet! :)
My Cartes Du Ciel only has the NGC cataloge and Tycho 2 stars
loaded, so the second night (and some homework that should
have been done on the first night!), proved it was just
a faint mag 14 IC 2913 :)
A comparison image of IC 2913 is also attached courtesy SkyFactory.org
NGC 3717 is listed as mag 12.6 in Burnhams.
