M1-Bicolor HOO

Started out with just Ha. I wasn't sure I'd continue with this one--was testing the waters so to speak. Conditions were pretty bad for this data--a full Moon and poor seeing. I ended up throwing out almost half the Ha subs due to elevated FWHM values. I wanted to use my new guide cam that has much smaller pixels so my guiding resolution would be higher, but it was -10C and I just could not get myself to start fiddling with connections and cables. Seeing as the clouds rolled in around 11:00 I am glad I waited.

--I added 44 300 sec OIII subs and 40 or so 300 sec Ha subs. Version D is a bicolor with Ha and OIII. I think I used an HaOIII integration as the green channel--trying anything to improve the palette and detail, which I am not too happy with. I struggle with Bi-color images (except for 2 noteworthy targets--the Veil and Thor's Helmet....and maybe the Squid and flying bat, but I have yet to image them successfully).

TOA 130 with ASI 1600; 111 300 sec Ha (Astrodon 3nm)

45 300 sec OIII (Astrodon 3nm)

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.
