Thanks!

I am not getting as sharp an image as I'd like. I need to concentrate more on
focusing. My drive is tracking okay unguided. I dunno.

DSO images are also kinda dark with the D40. I read that the D40 applies its own
internal median filter after each raw image, and you could lose some detail as a
result. Need to ready more about this.

Anyway, if it's clear again tomorrow (current forecast says so, I'll go for 2
hrs of data).

Cheers,
Phil

hope to get some good attempts at it soon. While the weather was good I got my
observatory up and partly debugged. The weather has caved in a bit here
(Vancouver BC) but it is looking better over the next week so I hope to try
myself soon.

I only got half of the amount I was targeting for due to clouds rolling in.
