I wasn't going to post this but scrolling back, this is possibly the first narrowband carina of the season!?
We've been fortunate enough to have some clear nights even if the seeing hasnt been amazing, so I've had the gear out a fair bit. Working on a target that is rising around 1, I've been picking off some classics til then, and last night I thought I was due for a win, so went with the closest thing to a guaranteed outcome.
This is 45 to 50 x 120s per channel Ha, Oiii and Sii. SHO hubble palette. Gain on the 1600mm pro was 200, as my main target is dim and I don't want to switch gains when i get out of bed at 1. Guiding was decent, a tick below an arc second total RMS.
There is so much signal here that I barely did any processing. No topaz denoise, no sharpening, I didnt even pull green down! The colour balance is as it was when combining channels. All I did was get the magenta out of the stars, auto stretch and a tiny bit of curves to get more contrast, and I think 0.3 on the ol' local histogram transformation in PI to get better definition in nebulosity structure.
I'm not 100% sure why, but the file size is actually quite small at about 9MB. This is 100% uncropped (so the edges might be a bit ugly) and usually I'd be around 19mb or so... I was wondering if it was lack of noise.
Anyway, here it is. There has to be one, at least. As always 9MB to 188KB means its pretty soft here, but I'm not sure if the world of astrobin needs another carina.... hmmm... maybe IIS doesn't either. Sorry, I'm happier to use server storage here than there.
A very interesting Carina to look at JP. One of the few I’ve seen that really shows the dark nebulosity is in the foreground. Often it looks like that band running through the center is just an absence of nebulosity but yours really shows that it’s being hidden. Well done !
