Cygnus Loop

Narrowband first attempt

After 2 years of struggling with the limitations in imaging of my Bortle 6 backyard and DSLR, and with little prospect of moving to a better astroimaging location in the short term, I've shelled out for an ASI1600MM-Pro and an EFW with a set of narrowband filters. \o/

So to test out and get used to the new gear I picked a relatively easy widefield target of the Cygnus Loop, SH 2-103.

Version G - Version E SHO with more denoise/sharpen (StarTools Matrix RGB:ROB)

Version F - Version C HSO with more denoise/sharpen

Version E - SHO in Gimp with denoise and some star removal

Version D - missing!

Version C - Processed in Startools HSO Palette

Version B - Processed in StarTools

Version A - Processed in Gimp

Between 19-25 Aug 2019:

Redcat 51 with EFW and ASI1600MM-Pro controlled by Ekos/Indi. 30mm Guide scope using Ekos internal guiding with dither.

- 75 x 300s Ha

- 50 x 300s OIII

- 35 x 300s SII

- 30 Darks, Flats and Bias. I didn't use the flats in processing as they made the images looks awful. Not sure what went wrong, I just used the same (white T-shirt) method as I did with the DSLR, except doing a set for each of the narrowband filters used.

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.
