M101 - The Sequel...

We had one clear night, just before the moon hit first quarter. I decided to try and get that extra integration time on M101 before it "rotated" too far from my March 6th session data. I wanted to be able to easily combine the 3/6 data with the 3/31 data. Thankfully, I was able to get more than 3 hours of subs on March 31st. Those combined well with my 3/6 data - without the need to rotate the camera.

Also, I have been able to re-use my flats for the past 2 months. I know some people reject that idea, but so far, I have not been able to see any ill effects. Same optical train, nearly identical focus points, and no camera rotation -> reusable flats for me.

At this time of year, M101 hangs out right above my roof line, and right above some nasty parking lot lights. So... lots of LP to deal with. Other than that, this session was great!

Thanks for looking!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
