M1 - a ‘positronic’ brain

Revision title: Processed using SIRIL photometric color calibration, and cropped.

A narrowband combined image using my mono and OSC cameras, taken over two nights. I’m awaiting technical support from Ikarus Technologies regards my Stellarmate, so have reverted to APT running on Windows XP and guiding using PHD via my Star Adventurer mount. Frames from each camera were aligned and combined using translation, rotation and scaling in Nebulosity 4, and processed in Startools 1.8.

I’m happy with the colour and level of detail considering this is a fairly flimsy mount for long exposures. This supernova is a fascinating subject, which continues to evolve year by year. Amazing to think the original stellar explosion was visible in broad daylight for over 20 days and in the night sky for over 6 months.

[Postscript - I’ve removed the original image, which had some processing artefacts due to incorrect alignment. I’ve added a crop as revision E (mouseover) and the mono data as revision F]

Description: Another rehash of data o cloudy nights. Pre-processed in Nebulosity then stretched, and colour calibrated in SIRIL, followed by star reduction, smoothing and noise reduction in Nebulosity (using GreyCstoration). I actually prefer the colours in M1 in the original HOO image (L-eNhance filter) but the stars look much better with photometric calibration (SIRIL).

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.
