Messier 101 - The Pinwheel Galaxy in LHaRGB (11 hours) - My Third Attempt at this Target.

Messier 101 - The Pinwheel Galaxy is a classic target that I find myself revisiting. My first attempt was in 2020, shortly after I started doing Astrophotography. It had a 2-hour integration and came out pretty well.

My second attempt was in 2021 using a new mono camera and 15+ hours of integration. Thin clouds and a pattern noise problem made this image a disaster. Very disappointing.

This - my third attempt - was done with an Astro-Physics 130mm f/8.35 APO on a CEM60 mount and an ASI2600MM-Pro camera. It was shot in LHaRGB with 11 hours of integration.

Still not perfect, but a step up from where I was on this target. This target is located in the sky where I have light pollution so it is always a challenge.

The story of the image and complete processing details can be seen on my website at:

Thanks for looking, and let me know if you have any questions!

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.
