View Full Version here: : Corona Australis

Greetings all, took this last night with 60da and TSA 120. 5 min subs x 100 minutes. Also took another Trifid which I am happier with, and a moonwashed M83. Damn big files so here's a link, as they look just daft when you try and shrink them.
NB EXIF on camera was about 15'c, ambient went from 3'c to 1.1'c whilst I was out there on my deck. Had frost on my chair when I finished up!
Was quite refreshing!

Nice, but some look a little noisy considering the temperature, did you take darks?

did have darks and flats, I reckon it was the moon as it was across the sky.
Also stretched it a bit to highlight dark nebula.

Actually, the Corona Australis is quite detailed.

I love that little twist of light within the neb. :)
If you do a repro, keep an eye on that glob, he's rather burnt out in the core. Ideally you should still be able to resolve it.

Quite nice Graham. How are you finding the 60Da?

(60Da) I like it alot Midnight, the other reason this might be a tad grainy is that this was shot at 1600 iso as I wanted to max my light gathering between clouds and moon.
All good tips -will have another look at this later on

I redid this to not burn the glob out and leave subtle detail in the variable triangular nebula.
Thanks for all the tips ( I'm lookin' at you JJJ!)
