M 1 Posted By dietmar hager

hi folks,

I have had a long night yesterday.
I decided to capture one of my least favourite nebulas: M1

data:
9" f/7 (with a reducer) TMB Apo
sxv h9c
AstroArt4 for image acquisition, stacking and color conversion.
postprocessing in PS CS2 and PixIS
3 hours of total exposure time.

I hoped to see more of the faint blue haze around the main nebula - but to achieve this I would have to go back again,...
no filters were used.

hope U like it!

NGC 2403 - 16" RCOS Posted By dietmar hager

hi folks,

I have had the opportunuity to process the data coming from my observatory-mate (he owns the 16" RCOS on a Paramount in an own obs.) Martin.
he has captured NGCV 2403 for 5 hours with the S-BIG 2000 XMC.
I have gotten his stacked FITS file and this is waht I have obtained after color conversion in AstroArt4 and postprocessing is PS CS2

the RCOS scopes seem to be terrific optics!!

hope You like it and - comments appreciated as always.
thanx!

M 109 Posted By dietmar hager

hi folks,

I have had the opportunity tp process another data coming from MArtin`s 16" RCOS, that is attached on a Paramount.
this time: 4 hours
S-BIG 2000 XMC

I have ccolor-converted the stacked FITS in AstroArt4 and postprocessed the whole thing in PS CS2.

what I`d like to ask You:
Martin stacked in CCD-stack. when he converted the image into colors, it has gotton all brown. disgusting almost.
what software do You guys use for colorconversion of the S-BIG 2000 XMC ???
I used AstroArt4 but I`m not sure if this is perfect...?
what I have found was (no matter if deinterlace on or off) a rather huge noise in the background,...
thanks!
Dietmar
