Fleming's Triangle HOO WIP

[DaveS]

This is still WIP as I need more, better, data. the subs I have up till now have been plagued with passing high cloud and early shutdowns triggered by the weather monitor.

Nevertheless, here it is, 7 hours H-alpha and 6 hours [OIII] in 900 sec subs with the ODK rig. Stacked in DSS and brutalised in AstroArt 8. The H-alpha data had full calibration, but the [OIII] only Darks since 1) I stuffed up getting sky flats for [OII] and [SII] and, 2) adding Bias stuffed up the stack.

Note the file says "Third HOO" which might give an idea of the thrashing around I was doing.

Still some uncorrected gradients to get rid of.

Program of further work, collect more, better [OIII] to replace some of the dodgy data, collect new, correct calibration frames.

Looking good. You have some very fine detail coming through.

Lovely Detail Dave.😎

[DaveS]

Thanks both.

 

Still hoping to get enough data to be able to apply a touch of Unsharp Mask without stuffing up the noise level.

[MarkAR]

Excellent work so far, lots of good detail coming through.

[DaveS]

Slowly getting there. Added another 2 hours of [OIII] but also the correct calibration frames. Pulled 40 subs [OIII] and H-alpha into DSS and stacked the best 75% with full calibration for 7 hours 30 mins each. Bashed the resultant subs around in AstroArt 8 and saved as PNG. Was able to apply a touch of Unsharp Mask without stuffing up the noise.

 

 

Possibly pulled the Red down a bit too much, may have a think about it.

Looking really good Dave

Looks like you lost a bit of the blue wispy stuff compared to the original.

[DaveS]

Yeah, could be. I was trying to avoid too much noise in the background, may have pulled the Black Point up too high.

Will revisit it after having a break. Wood and trees and all that.

Photoshop says your colour is perfectly balanced, and you haven't clipped the black.

Looks really good. I think this is an overlooked area of the Veil complex, but it's wonderfully intricate - as this image shows.  I'm inspired by deep dives into bigger targets.

[DaveS]

Yep, this area is becoming my favourite part of the Veil Complex for its intricacy. I'll have to pause my capture for this year, but will continue to work on the data I already have.
