Cygnus Panorama - Finished at last - 144 hrs integration (urmymuse)

Cygnus Panorama - Finished at last - 144 hrs integration

Hello Astrobin friends!

Here is my final version (for now?) of my Cygnus panorama – its been a massive effort which is hopeful worth it

I have now cleaned up various issues with the Ha and Oiii combination of data from the Redcat 51 and …

I have merged in data for the main objects that I have captured with longer focal length scopesAlthough there is some loss of detail by reducing the size of these images to match the 250mm focal length there is more detail remaining than original captured with the Redcat 51.

I started consciously doing this in spring 2023 but the earliest data in the image (only a tiny sliver) dates back from May 2020

Thinking about it the image now contains
·       144 hours of exposure time
·       Data taken over four years
·       From 3 locations (Leeds, Ermita Nueva in Spain, Boughton Malherbe in Kent)
·       Data from four scopes (Mainly Redcat51 @ 250mm then 520 mm, 728mm and a tiny bit of 800m)

I have learned a lot in putting this together – i.e. made many mistakes along the way. The key thing is planning which I did very little of lol

The process of lining everything is tiresome and I guess there are some imperfections still but nothing too noticeable hopefully.

There were a few occasions were the bit of sky I thought I captured turned out to be entirely different to that intended – probably due to error in inputting the coordinates whilst enjoying the vino a bit too much in Spain 😊

Matching the colours was challenging also and the density of the star fields due to different sky qualities moon phases etc

I should say that I thought of trying this after getting the “Visible Universe” by Bracken and Whitby (they have created an image of the entire sky!)

Thanks to the fellow Astrobiners who have encouraged me along the way

There are further enhancements I could make on this (RGB stars?) but I will probably try this approach for some other areas of the sky first, we will see.

Please do have a look and tlet me know what you think !

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.
