IC5146 Cocoon Nebula

I have been making changes at my home observatory to try and make best use of the clear skies as and when they happen and to try to not be limited to clear hours that are relatively social.

First is the successful implementation of an automatically opening (and closing!) roof and as a result I have been able to collect more data. Secondly, I have two mounts, each of which has a multiple scope system; one an identical dual 1200mm rig and the other a quad 400-600mm rig.

Both systems have been a significant pita to get balanced, aligned and especially communicating with each other and the roof and the brains of all this is Voyager Array working alongside AMS in the background. After some protracted health issues, I chose some well known DSOs and this is the first true image from the 1200 system though i also pointed the widefield rig at the same object.

Between the two scopes, this image of IC5146, was taken over six patchy nights between 16th and 29th August and includes,

56 x 180" and 104 x 300" Lum,
27 x 120" and 112 x 180" Red,
96 x 120" and 10 x 180" Green,
and 15 x 120" and 79 x 180" Blue

I mixed the different channels between the two scopes and because they are identical systems, integration was very easy and much of the noise disappeared despite the relatively light integration time for NB.

After rejections, Scope 1 total integration times Lum 168', Red 278', Green 162' and Blue 252'
After rejections, Scope 2 total integration times Lum 520', Red 114', Green 192' and Blue 30'

Thanks for looking

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.
