M51 - 'all in'

Revision title: Cropped and colour balanced

Another image combining data from all my cameras and telescopes (2 of each, lucky me) with very different pixel sizes and imaging scales.

With 4 hours data there is definitely more depth in the image. I have perhaps not stretched this as much as I could, partly to suppress gradients in my earlier images.

I combined data from my WO 80IIED semi-APO and Meade 2080 SCT. Field rotation between images made alignment and stacking difficult.

The revision brings the ‘best of both’ 100m of L taken with my SCT at f3 using my DSI III PRO mono CCD, and 100m OSC using my 183C CMOS.

Personally I like the revision better, with finer detail and a better balance across the core and star streams.

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.
