I used SVX130 refractor and ZWO ASI2600 OSC camera. I just finished taking the camera apart and cleaning the sensor since thermal grease had leaked onto the sensor. SV90 and ZWO ASI290 used for autoguiding. SGP managed all of the equipment.
Since the sky was bright and there were wind gusts, I started the night by taking 1 minute exposures. After 2 hours of 1 minute exposures, I switched to 2 minute exposures for another hour. I then took 50 flats (0,1 sec). My hope was to try and capture some of the nebulous region.
Image processing this object was much harder than expected. Getting a decent image of the open clusters was easy, but trying to pull out the nebulous region (lower left) was a challenge. I tried several different stretching processes, and was only able to show faint red nebula. If I ever decide to re-image this area, I will have to do so when the sky is dark, and I can afford to take longer exposures.
The good news is that I looks like cleaning the sensor solved the problem of the thermal grease leakage.
M38, also known as the Starfish cluster or NGC 1912, is an open cluster in Auriga. The smaller open cluster NGC 1907 apparently originated in different parts of the galaxy and is doing a 'fly-by'.
