A Beehive in Cancer

Moving over to using APT for my previous session I found it to have many advantages over simply using the camera cable release, coupled with reviewing images on the camera LCD screen. So again using APT with some "proper" shooting profiles in place, I wanted to focus on maintaining sharp focus and eliminating drift and trailing with decent polar alignment and constant monitoring (with the PoleMaster). This proved successful overall and resulted in some of my sharpest frames to date, along with more data than I usually capture. Unfortunately my composition on M44 ultimately suffered from a neighbouring house chimney creeping into the frame, which meant the necessary square crop and an abrupt end to capture by about shot 28!

21x light frames / 30s / f4.5 / ISO 400

10x dark frames

41x flat frames

~50x bias frames

As usual, image calibration, registration and integration performed in PixInsight, followed by the crop, stretch, and colour calibration before importing into Lightroom for some basic editing of highlights, noise reduction, contrast, dehaze and some hot pixel removal.

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.
