Prawn revisited - IC 4628 in SHO APM130 with 0.75x reducer

I do like the prawn nebula. Maybe not quite the same detail and Lobster or Running Chicken, but plenty of interest and a lot of fainter background nebulosity that frames the brighter portions.

I imaged this earlier in the year, but with a straight flatenner which at 780mm FL on my APM stretched my guiding a tad.

So I've revisited over a couple of nights using the riccardi 0.75x reducer giving me 585mm and faster F4.5, so with the 12 hours here should be effectively gathering a lot more "light" than previous 11hour integration at F6.

Also decided to do this one in portrait orientation for a bit more differentiation than simply a wider field shot of previous image.

Stacked into separate Ha, OIII, and SII channels in APP and recombined as SHO in Startools 1.7.

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.
