GAHD DAMN probably the best globular cluster image ive seen and I wrote my dissertation on star clusters lmao
theres a little cigar and bodes clone down there lmao
That's dope
there are actually so many background galaxies i wasnt expecting it
What in the world dude
this is stunning
All those background galaxies are incredible to see, and the sheer definition on the stars here is shockingly good, your stars are such small pinpoints, and that lets you see so many more than usual, what's your arcsecond to pixel size ratio?
I'm just in awe at this image
MAN just banger images getting sent to this server lately, I really, really like your images!
I'm not even a fan of star clusters but wow, this looks amazing
How did you get the stars so blue!? This is really nice looking
bro s competing with hubble
Great image!
I have GOT to lock in!
Super cool image! love it! but one thing to notice (and may be worth checking out) is the diffraction spikes
they are bent/spliting on the stars. It happens to me because my spider is abit bent physically, so figured may be worth mentioning and checking over
the spider vanes are carbon fiber and locked in place, they cant be adjusted
i think it's more of a blurX (for the yellow star) and tilt (for the blue star at the corner) thing, also when i took this data the scope wasnt as well collimated as it is now
i havent noticed in more recent data, but i will keep more of an eye
thanks
i stand corrected, they can be adjusted
scope being remote i wasn't sure
next time i will go there i will take a look
Wonderful!!!
Tbf i was more worried about a bend in the spider itself, but yes definitely worth giving a check over, diffraction spikes can be a good sign of something off
going off of what @sharp wing said, sometimes blur-x would make my newt diffraction spikes curve a little bit if the signal on them wasn't 100%, although I do see a little bit of the physical bend, as I haven't seen blur-x create 2 diffraction spikes on one side
BlurX doesnt curve star spikes lol however is the spike is already curved/bent it will make it more pronounced because its "sharper" but deconvolution doesnt bend things, and yeah the spliting star spike is a huge giveaway of spider bending or something off with the spider
nope, the splitted spider at the bottom is a tilt/backfocus issue
my backfocus is not perfect
this is how it looks on the raw data
the star is out of focus, then blurX tries to fix it and produces that result
screenshot of the raw stack
this was taken after i went to spain to fix collimation and backfocus
i'd say spikes are normal there
Good point, forgot backspacing and tilt etc can cause spliting spikes. Seems on the new image it is definitely better, atleast theres no issues! but always worth mentioning, couldve been much worse than abit of backspacing and collimation
