31hrs LRGB of Sculptor Galaxy - NGC 253

The Sculptor Galaxy imaged from my backyard, large thanks to a telegizmos 365 cover. First imaged around 1/10/22 through to 03/12/22 over about 18 nights.
My scope is around 1484mm focal length and repeatably decent guiding has been difficult.
There were varying amounts of moon over the imaging period although I tend to stop shooting closer to a full moon.

The Sculptor Galaxy was a bit tricky to get lots of time on due to the shorter nights but I think 31 hours was a good effort.

This is the first time i've used BlurXTerminator plugin for PI, I used sharpen stars @ 0.25 and sharpen nonstellar @ 0.3. The results worked quite well and saved a massive amount of time and effort investment that Deconvolution involves.

I also used two rounds of NoiseXTerminator plugin, once for the Lum master in it's linear stage and another on the LRGB towards the end of processing.

Apart from that I've gone to massive efforts to optimise my optics and mount setup to squeeze as much performance as I can out of it before the editing stage.

Typical guiding RMS ranged around 0.4"-0.5"RMS with subs exceeding 1"RMS excluded. A dozen or so subs were able to be captured below 0.3"RMS ranging down. Not too bad for a portable EQ6-r setup.

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.
