My first mono Galaxy - M83 southern pinwheel in LHaRGB

A couple of firsts for me, first time using an OAG and first time doing mono camera imaging of a galaxy. Not a great start with the OAG - it was intruding in the frame, but for this image, cropped as it is, didn't matter so much. Still playing with the right depth for the off axis mirror; i have since got it well out of frame but then stars were very elongated and poor for guiding... need some clear sky to see if latest tweak has the goldilocks zone.

This is my first go at doing LRGB as well, all previous mono imaging has been narrowband. I did do some Ha narrow band here as well to capture/highlight emission nebulosity.

I stacked in APP into the separate channels, then combined and processed LRGB in Startools 1.7. Haven't found a way to combine in the Ha in Startools (question for Ivo) but processed Ha separately as Mono colourised as magenta and blended it in lightly in PS to add some of the emission neb colour here.

plenty still to learn on this type of processing!

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.
