Brief narrowband Rosette

[MartinB]

Wasn't expecting to get anything done last night, forecast to be cloudy by 9.00pm. Cloud and mist was descending just half a mile to the west of us but it sayed clear until around 10.00.

I took this really to try out my FSQ and QSI with a view to a project next winter (weather permitting). Pretty surprised by the results really. The Rosette really was sinking into the murk

Ha 5x400 secs

OIII 6x400

SII 7x400

all unbinned. 2 hours total exposure time 33 minutes Ha. The short sub length was chosen as optimal based on measurement of background skyglow.

Tak FSQ 106 and QSI 532. Captured and combined in maxim. Channels scaled and combined in maxim after DDP. Finished in PS. I haven't calibrated the images at all.

The colour has been mapped to the SII Ha OIII RGB. I've also added the 33min Ha.

Looking forward to doing more on this next year

May have been brief. 2 hours?, but looks very good to me.

Like I'm an expert. You're planning ahead to winter, so you have started preparing early which is good:cool:

Very nice, I really like to see images with the different colour mappings.

How did you go about doing this:

"The short sub length was chosen as optimal based on measurement of background skyglow"

I never know wheather I am shooting my subs for too long!

Cheers

Lovely result there Martin for such short subs , wish i could get that detail in such a short time . the narrow band is nice , but still prefer the mono, but then i guess i always will lol , great processing as always

Super result Martin glad to see you have managed to get out at last. If this is just a test then I cant wait ot the real one

That's a fantastic image, those FSQ are special, not to mention the QSI. As you already said its an even better result considering the position.

What's the winter project if I may ask?

Neil.

[MartinB]

Thanks guys. Neil, the winter project will be a lot more hours. I might use a 0.73 reducer to get it fully framed. I always have these plans and the weather always scuppers them.

Short is most definately sweet there amigo, very nice .

I have never really been a fan of the Hubble Palette, but when you see images like this and Eddie's of the same target, its easy to see why they go for that.

Gorgeous image Martin.

Not too shabby for "test" shots... I'd say you passed.....

Just thinking about Winter makes me shiver now...Good luck:D

[MartinB]

Thanks again guys. I've always struggled to get SII data before and was surprised to get useable stuff with under an hour of exposure. Definitely going to be doing more narrow band this Summer esp if my obsy gets sorted - M16 Pelican NA neb, close up with LX200 and wider with Tak.

After a couple of reasonable sessions I can feel the enthusiasm seeping back into me!

[Psychobilly]

Very nice

Glad a few sessions have cheered you up a bit all we need to do now is get Rog cheered up a bit...
