M33 - Triangulum Galaxy

M33 - The Triangulum Galaxy. Open face spiral galaxy in the Constellation of Triangulum.
Third largest of the Local Group - behind Andromeda and the Milky Way.
Spans approximately 20K LY and is 3 million LY distant.
Lots of apparent blue star clusters and pink star forming regions. Core seems bright but not well defined.

Used Pixinsight's new SPCC Spectrophotometric Color Calibration - worked as advertised out of the box - just accepted the satisfactory result without further experimentation.

I have gone around the sun once with my SharpStar EDPHII 61 and enjoyed some ‘wider’ field imaging. I have replaced the little wonder with my Stellarvue SVX 102 with the addition of a new .74 flattener / reducer to maintain some of the wider field imaging perspective. M33 is the first light for the .74. Pixinsight indicates the FL 524 mm, FR 5.25 and a resolution of 1.5 a/s using the ZWO ASI1600. Not dissimilar from the 80 mm scope I started with.

I am pleased with the image given the integration time. Hope you like it too.

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.
