Bo, I should have mentioned that I do have a reasonable understanding of how the f stops work in relation to exposure. I have played a lot in photography including 4 years of p/t schooling.
I also should have mentioned that the 4se has goto, so I am learning all about that at the moment. When we bought the 4se we were told that we would be able to see the Horsehead Nebula. We have since learnt that that is no where near possible. And I have also been told that you cannot upgrade a Dob to a Dob with goto, I didnt really understand why. I have since been reading about argo navis (sp).
I have been getting my head around AZ mounts, even though with the 4se it does not really play a part. I hope I am right in that statement. the 4se also has the wedge, I have not even started playing with that yet. So far I am simply setting it up (when we have no clouds) including alignment so that it tracks, and sighting a few items, not many, at this stage I simply have a 25mm EP and a 2 X Barlow. So a little limited.
Maybe a silly question, how does a larger Dob go on an AZ mount? It seems way too big from what my limited experience tells me.
Most of what I am learning is from sitting here reading. As I live on a farm I do not know anyone else that owns a telescope. For this reason I am greatly reading any responses I get, and then I read them again.
I am enjoying the learning though.
Cheers
Andrew
