Very much WIP - a rather noisy Witches Broom with 60 mins of both Ha and OIII combined as RGB (HaOIIIOIII). I need at least another hour of each to improve the S/N plus the SII channel so didn't bother with too much processing or noise reduction.
6 x 10 mins Ha and OIII Sky90@f4.5 with SXV-H9 guided with SXV Guide head and converted 50mm finder.

Wow! noisy or not, that's an incredible amount of detail, Love the colours! so much faint nebulosity captured
Daniel
:O)
That is superb Robert - tons of wispy detail - one of the best I have seen... Can't wait to see finished image. Why is the main central star slightly off centre of its halo.... Is that collimation issue...? Just curious cause I have the same issue on some of my images...
Fantastic - John
Really nice Robert. Tons of detail in there. One of the best i've seen of that part of the sky.
Robert,
Lovely colours, lovely detail. That is looking very good already!

Thanks for the comments, but around here it really needs at least 2hrs per channel.
QuoteWhy is the main central star slightly off centre of its halo
Interesting you should say that John; It's something this image has highlighted. Collimation changed continually through the imaging session which has highlighted a problem with the focuser. I now need to get it adjusted so there is absolutely ZERO play, which is going to be interesting. Also the Astronomik filters are known for the secondary reflectance issue so I will be changing over to the narrower band Baader filters which are supposed to give much smaller halos and are parfocal at f4.5.
