Only 5 frames!!!

Trifid Nebula, 2024-06-06, ZWO ASI2600MC Pro, 5x180s.  Celestron 8SE, ZWO AM5 mount, f/6.3 reducer.  Live Stacked with SharpCap.  Final stack with ASTAP.  Prineville Reservoir State Park.

The weather on Wednesday and Thursday nights was perfect.  In spite of a report showing wind gusts, there was little to no wind.  Setup took me a while each night.  But after getting my darks and flats the first night, I used those again on the next.  PHD2 calibration using the wizard was almost perfect.  Had to calibrate 2 times each night before locking it into a good calibration.  But honestly, it was worth it for the tracking.  I chose one target for Thursday night.  Tracked it for roughly 4 hours with PHD2.  And if I'm reading my log correctly, the RMS total was 0.77 for that time.  Wednesday, I saw anywhere from 0.60 total RMS to 1.23 RMS (which might be due to losing stars because of a tree). 

I've wanted to capture the Trifid Nebula for a while now.  I think it was ok to get 5 good exposures.  SharpCap just could not live stack.  So I opted to save the raw frames and stack them later.  In retrospect, I should have just let SharpCap continue to drop frames to get more raw frames.

Oh, and my other target of the Filamentary Nebula had not 1, not 2, but 3 (three) satellites crossing.  *grrrr*.  Otherwise, had a lot of fun!
