Wow... you're doing LRGB.

800 frames means 800 frames in total for L+R+G+B together or each channel has 800 frames?

Hi Oldfield,

800 frames are Lumenance one. For individual colour channels, I normal use approximately 100-150 frames which is enough. :-)

Seeing was no good and the transparency was low, so if I use colour camera one, the raw image will be too blur.

Phoneix hill was at the north east position of Shui Hau site, so I guess when the wind is blowing from north east, then the current sliding from the top of the mount will create turbulet.

I still remember in last summer, even the Jupiter was 45 degree above the sky but it was very steady especially when the wind was blowing from southern direction.

I may try imaging again tonight!!!

Best Regards,

Eric
