Messier 51 (Whirlpool Galaxy) in Canes Venatici

Link: https://stevemilne.smugmug.com/Photos/Sky/Galaxies/i-gbpGWpT

The Whirlpool Galaxy (Messier 51) is located some 27 million light years distant in the constellation of Canes Venatici. It was discovered by Charles Messier on 13 October 1773. In the New General Catalogue, M51 is designated NGC 5194 and its companion NGC 5195.

Messier 51 was photographed between 22 February and 28 March 2020 from a rig in Spain that is privately owned and operated by Barry Wilson and me. In May 2018. I imaged M51 from my home observatory in the UK using the identical telescope, camera and filters. As such, it seemed to make sense to reuse the Lum and Ha from the May 2018 run.

Capture details are as follows:

Telescope: TEC 140

Camera: QSI 690

Filters: Astrodon

Mount: 10 Micron GM2000HPS (2020); Mesu 200 (2018)

Ha: 21 x 1200s (2020)

Ha: 14 x 1200s (2018)

Lum: 48 x 600s (2020)

Lum: 27 x 600s (2018)

Red: 48 x 300s

Green 48 x 300s

Blue: 48 x 300s

A total of 36 hours and 10 minutes exposure.

Data: Steve Milne & Barry Wilson

Description: In looking at this image, I came to realise that it was probably too 'crucnchy' and that some of the 'detail' I thought I'd captured may well have been artefact introduced early (unfortunately) in the processing - maybe as a result of excessive deconvolution. So I reworked it from scratch. In the revision, I have not used any of the 2018 data.

It's cropped a bit tighter 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.
