I had a lot of problems with guiding on this particular night
PHD2 looked fine but after a certain point in the night the subs didn't ... stars looked like lines
I took an unguided exposure and this was ok , much better than the guided which I thought was odd
Finally gave up and went to pack scope up ... noticed heavy dew on the guide scope (not happened before) so maybe that caused it
Moon was also bright which seemed to reduce contrast as night went on as well ... even though shooting duo narrowband
Any way ended up with only 55 minutes of usable data ... have been trying to drag out the nebulosity but there not enough signal
Anyway I posting this very unimpressive looking crop as a memory of a most frustrating evening
Annes astronomy news tells us ....
IC 417 (also known as Sh2-234) is an emission nebula of almost 100 light-years across, located some 10,000 light-years away from Earth in the constellation of Auriga (the Charioteer). It is often referred to as the Spider Nebula and in that case its prey is a nearby emission nebula called the Fly (NGC 1931).
The nebula contains a young open cluster of about 40 stars, and is energized by its hot, massive blue stars which are still embedded in glowing hydrogen gas
