Gotta say im super proud of this image! the processing was very very difficult, had shooting this before and after modifying the Quattro made the continuum subtraction have some diffraction spike artifacts particularly on the bright stars in the galaxy, however despite (what i consider) a minor error, i love the Ha and OIII regions, it really makes the difference for this target! either way im very glad to have spent the time on it, wouldve done more but some targets are rising and i have a few projects i want to do

Scope: Quattro 150p
Mount: HEQ 5 pro guided
Guiding: ASI 120MM mini
Imaging cam: ASI 294MC pro
Filters: ZWO UV/IR cut: Optolong Lenhance triband
Broadband exposure: 11h 30m (230x180s)
Narrowband exposure: 11h (132x300s)

22h 30m total

Shot from Sept 9th to Oct 3rd

This is such an ideal process of triangulum to me! When I get around to shooting this, this is exactly what I'd want it to look like

Thanks man! its got its imperfections though so im likely gonna reprocess it soon (that bottom right corner of the galaxy got abit too much magenta noise)

the sheer amount of nebulosity in this galaxy never ceases to amaze me, and you've captured this fantastically!! Some of the stars have odd shapes to them, but I don't think it takes anything away from the overall quality of the image.

Ultimately i wanted 20-30 hours of narrowband data, but unfortunately its getting abit too late in the year for me to want to continue it sadly. For the stars i assume you mean the brighter stars in/around the galaxy? if so then yeah thats the narrowband data and broadband data not being aligned (i changed the spider for the broadband data so they arent aligned) however it is fixable in processing and i plan to reprocess it (:
