I've been catching some narrow band Rosetta between the clouds and thought I'd popup what I've got although some RGB for star colour would be nice.
This one is 9 x S2 @1200seconds, 8 x Ha @900seconds and 15 x O3 @1200seconds.
Tak FS-60 @ 380mm FL. No Flats.
[edit]
I found the S2 and O3 filters where reversed when taking flats so I've uploaded the corrected final including RGB stars. Also added a version which uses tone mapping techniques.
The weather being a real pain at moment mike. This one is over 5 nights so far to get 10 useable hours worth. Only got 40minutes worth last night before it closed in again and it looks like more of the same for next week
Nice job Robin. You can reduce the magenta stars if you don't end up doing RGB ones with selective colour and work on the magenta selection.
I think there is a tutorial around about how to reduce the magenta stars other ways. Probably a star mask and the reduce noise tool in PS with colour noise slider pushed hard.
Green in NB is not my taste and it comes about usually because ha is assigned to green in that palette. To compensate for the stronger green signal you can do pixel maths on the RGB combine say 4X or 8X for the red and blue and then combine.
Or boost red big time in curves and perhaps levels.
Cheers Greg, I took the settings in this web page for hubble colours and fixing stars and put them into actions. I think I might have run the star fixer before I finished stretching this one, it normally works pretty well. I don't mind Ha as green, although lagoon is striking, but yellow, if you swap them around. Getting enough info out of S2 and O3 to match it is the real problem. Ha seems to have all the detail in this one, S2 and O3 look like mist.
Cventer, what's an STF? A filter wheel?
Cheers Carl.
Might get another little go at it tonight by the looks, but a cooled camera seems to attract thick clouds around here lately
Ahh, Sbig STF. I had an ST8300 mono for a while a year or 2 back.
All clear tonight, all night, so I got the rest of the data plus some RGB and flats as well. Time to change the scope and move on
Before this capture I installed the new ascom driver for the SX wheel.
It appears that in that process the S2 and O3 slots got switched.
Shooting flats has proved it, so the first image is arse about.
The core should be blue like this one.
You know I even looked up the spelling this morning That's what 13hours awake and half a litre of bourbon does to ya at 5am
Here's a Sidonio with RGB stars added and probably not the last. I shot the S2 next to a full moon, unfortunately it was actually O3 so a lot of them got the boot
Cheers guys, yep that fs60 is a neat little scope for the size.
I thought I'd get myself a copy of gradient xterminator for xmas and recover some of the subs I didn't use Here's the final repo.
Great detail, although I personally prefer the version from the 18th @ 4:35pm. I prefer that particular shade of blue and I think you had more contrast/detail in the "brown rim".
only imaged it once before in Ha only, through a 200mm lens with a small chip so I think it's overdue
