Hi,
Finally, a reasonable clear night on Friday for my Vixen R200SS, Canon 450D and IDAS LPR filter to took their first DSO image...
The high/passing cloud and light pollution cause a big patch of orange "nebulosity" all over those spaces between the stars... try my best to reduce/remove them, but some "leftover" was still in the image if you look closely due to limited skill in image processing... . Will try again when got more free time.
The polar alignment was not that good, but it was still usable. No flat frame applied as the orange "nebulosity" look very odd (even more difficult to remove it) if I applied the flat frames... will take a look at it when I have more time. Also, the white light from the LED lighting I used to make the flat frame become blue after passing through the IDAS LPS.
Anyway, I try ISO 400 this time and the result was quite good, but I think ISO 800 might be better.
Below are the settings:
Images: 40 images x 2 minute exposure @ ISO400 (unguided)
Dark frame subtracted and No flat applied.
Have a nice day.

Hi,
Anyway, will edit my first post.
Have a nice day.
Oops... No lah... it's those small battery power LED lighting I used for taking flat frame. The white LED light will shine on a white cardboard I place in front of the scope.Tachyon wrote:Nice! What LED lighting are you referring to? Is it the LED torchlight or something from your equipment?
Anyway, will edit my first post.
