IC443 - widefield in 70mm Pentax lens

With poor seeing conditions recently, Gemini offered an interesting alternative target for a wider field image. This image at 200mm in my Pentax zoom lens just about shows the jelly fish nebula IC 443, a supernova remnant beside the bright star propus, and the faint nebulosity SH2-249. M35 NGC 2158 is visible at the top right side of the image.

This region definitely warrants longer integration and deeper exposures to bring out these nebulae; each DSO demands longer focal length to bring out the details under better seeing.

Captured with my Altair 183c OSC and L-eNhance filter (2x2 binning) in Nebulosity with PHD2 dithering. Unfortunately I lost the flats which I took using ATP flatsAid, and I need to increase my dither with these short focal lengths.

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.
