My fourth go at the Pinwheel Galaxy !

Taken through April apart from the Ha which was taken last year using my Orion Astrograph

Couple of firsts for me in this 1) First time combined data from different scopes and cameras 2) first time have used that new Spectrophotometric colour calibration in Pixinsight

Galaxy season this year has been heavily impacted by a) clouds but b) having our roof done which has meant two of my my semi permanent set ups had to be moved and wrere out of action

Lume 682 x 30s
Red 268 x 30s
Green 239 x 30s
Blue 236 x 30s
Ha 84 x 300s
Total 18 hrs 52.5 mins

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.
