Flame & Horse at Lostock

Guys...as most of the imaging boys at lostock were aware I was having major problems with noise on this target...I spent 2 nights just imaging this target with the same affect...I was using a UHC-2 filter which looks to have been the cause of my problem...the noise ratio was too high.

I had enough by the second night so I decided on the last night I would take an image without the filter with improved results....and considering I spent a full 2 night on this target I didn't want to waste another so I moved onto Orion.

Very dissapointed in this image but I said I will post it.

15 x 12.5 Minute guided exposure ISO800 on the ED80.

I have lost a lot of detail due to darkening and reducing all the noise and I mean noise heaps of it.....oh well next time I wont use the filter...saying this the UHC-2 filter works exceptionaly well from my light poluted skies in Brisbane...I now know not to use in dark skies...atleast I learnt something.
