M27 - DSI III Pro and Zenithstar 80II ED

My first attempt at 'dual rig' imaging - widefield of Vulpecula using AA183c Hypercam and 75mm SLR lens, and this image of M27 star field using my Meade DSI3 Pro mono camera and Zenithstar 80II ED semi-Apo - on my homemade mount attached to an old LX6 fork drive.

I collected around an hour of data (15s exposures unguided) with the DSI 3 Pro using Nebulosity image capture, pre-processed using ASTAP (best 38' subs) with minimal processing in Startools. (The widefield image was captured using 60s exposures in APT).

I was happy with the calibration and managed to remove most of the light gradients. Focus was reasonable using a homemade Bahtinov mask. I may try and add some broadband colour to this - forecast clear and semi-dark on Friday/Saturday... hopefully.

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.
