IC1805 and NGC896 The Heart and the Fish Nebulas in SHO

Revision title: IC1805 and NGC896, The Heart and Fish Nebulas in SHO

This is IC1805 (Heart) and NGC 896 (Fish) nebulas. There are numerous other objects in here such as Melotte 15 (the central cluster which irradiates all of the gas). This object is somewhat of a test, as it is very under-sampled. I shot this with the Stowaway and focal reducer and 60mp camera binned 2x2. So <500mm focal length with pixels that are about 7.5um square. It can't be blown up super big as the stars go square. But the 2nd part of the experiement is to drizzle the image and re-inflate it. I know I can't really get detail where I didn't capture it, but my stars do go round in large zooms. I will post the drizzeled version soon. In general, noise is very low and the signal I get at 20 minutes is incredibly low (< 60 mean count over bias at 100 gain) but still get a good result (at least I think it's acceptable).

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.
