M63 - sowing seeds

An experiment to combine data from my Altair 183 OSC CMOS (2.40 micron px) and L frames from my DSI III pro CCD (6.45 micron px) cameras. A bit like sowing seeds, you never quite know what you are going to get, and strangely these data were taken exactly one year apart.

I aligned (translation, rotation and scaling) each stack in Nebulosity v4 and then processed in Startools. The mouseover shows the mono stack following stretch and curves, with unsharp mask. In Startools - stretch, wipe, sharpen, deconvolution, tamed core, colour balance, healed stars (removed blooming artifact and de-warped), and final noise reduction.

The image comprises 62 x 180s OSC and 63 x 120s L frames. I'm pleased with the boost to detail in the core (I expect I suppressed the halo in my processing). I think there is potential here to image at different focal lengths too.

Title: Bright and colourful

Description: Whilst I try and emulate the 'natural' colours of the objects I image, using Startools 'scientific' colour constancy module, it is fun to play sometimes. Here I've ramped up the saturation showing off that wonderful flocculation and colourful stars... or perhaps it's just a distraction?

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.
