aad_Dira,

Looks like you're starting to get to know your setup. The exposure at this FL can made the difference between a washout and a good image with decent detail. Keep going!! You're doing well without a telescope at this stage!

Anyway, Im starting out too but I do have a 8" telescope although it is getting on a bit and the LXD55 is sort of frowned upon by all but back in 2003 when I got it, it was in my budget but not a "cheapie" and for observing it has been absolutely fantastic. But since I got a Canon 40D for a present recently, this astro photography has opened up a dimension in astronomy I could only admire in astro magazines (and still do!).

Anyway, here is a new photo taken tonight of the moon - Canon 40D prime focus into my old LXD55 but this time some changes thanx to Brendan for helping me understand turbulence and Chris (Omaroo) for some finer tips.

This image is from a 40D, prime focus, stack of 48 (from 70) in Registax, at 1/180sec, F16 (via a 2" external mask which made one hell of a difference to fine focusing), ISO 400 and daylight white balance. I am terrible at Photoshop so I just can't get that nice "steel blue" in Chris' image but I seem to have got the focus and stacking good - maybe ?? for now, I steer clear of Photoshop but slowly learning. Anyway, image 2 shows 1 frame that is average due to atmostphere, yet image 3 is a shocker yet is only 2 frames later (about 1/2 sec later in fact!!). Note the HUGE change in clarity. What I learnt from this is the huge variation in focus frame by fame even though I haven't touched the camera - ie atmosphere as Brendan points out!! This now really explains my grief at liveview and actual photo as per my post earlier this week.

aad_Dira, keep going and try cause I am finding the help here at Iceinspace absolutely first class and I found this "hobby" just a past time until the last week or so since I joined and these guys and gals are so full of tips and helps that are more than happy to give us beginners tips and good directions

Cheers,
Darrin...
