Tibet Posted By dietmar hager

hi everyone,

many of you have learned in the mass media about the oppressed people of Tibet.
(I have learned for my friends who work for a peaceful solution for the "tibet-issue" and support tibetan refugees locally (in Tibet), in northern India and Nepal)
for many decades this people has been suppressed by the chinese government, that deprives them of their human rights.
here is a possibility to support a petition that has its goal in bringing the violations to an end by having both, chinese government and tibetan representative(s) (Dalai Lama) take a seat at a round table and find a peaceful solution.

more data on Tibet can be found here:

I wish to pronounce, that - by no means - I want to offend Chinese people; it is just about the chinese government that does not act according to human rights.

Tutorial on Pix Insight LE Posted By dietmar hager

hi guys,

I know this comes late, as there is a new and full scale version of this software on the market.
however, on request of many I have created a simple tutorial on 2 procedures I really love to perform in PixInsight LE.
The full scale version I know is capable of wonderful things, but is quite complicated, I think...
at least this is what keeps me from digging through this new software...(particularly the wavelet-function)
So still, I do 2 major steps in my DSI processing with Pix Insight LE.

there is one tut covering

- the creation of an arteficial flat; and one that covers

- background-noise processing with a mask

the arteficial flat is interesting for all those operating One Shot Color CCDs, as it is difficult to gain a decent flat with OSCs.

perhaps you find these useful.

NGC 2158 Posted By dietmar hager

hi guys,

here is an image I processed as a crop of the overview M35+NGC2158 I posted recently.

NGC 2158 looks like a glob. cluster but sure isn't.
it is pretty old, said to count some 1 Bio. years and seems to be located 10800 LY from earth. it's true nature was only revealed in the 70s last century.

we're looking at 2 hours total exposure time.
SXVF M25C - 4+8 min subframes.
5" TMB f/9

please find the image, all data and the overview including M35 here:

thanks for looking.
