Thanks for the reply Robin,
Yea, I guess I am excited, but I got enough time on hand at the moment to get stuck into it & enjoy doing so. With so much info out there on the net, books & magazines, it seems I get a bit of practice while saving. Nothing beats hands on though. I don’t believe I’ll be wasting any money –I never do with my purchases- but thanks all the same. I understand what you’re getting at. Oh yea most people find the highlighting more useful to read though; if anything I should of spaced out the format.
To answer your question:
“I don't know why you are worried about the secondary mirror or why you would want to move it. I think you have your wires crossed there.”
I thought the secondary mirror was the one to move in relation to DSLR Prime focus with Newtonians? If I have this wrong, could you shed any light on the subject?
The reason I highlighted was to clearly show what statements in some of the forums I was having a hard time understanding…Obviously not everyone will understand either or perhaps my questioning and format, as you say, is too hard to read?, but I think it’s clear why I thought the mirrors had to be moved.
Thank you for bringing to my attention “the focuser to a low profile cayford style + inclusions of compatible extension tube” This must be dependant on the camera as I can’t understand why people would go to the trouble of moving mirrors for prime focus if this method works.
Here is a specific question for you?
What do you mean by “real Astro Camera” is like that what some call a dedicated digital sensor for astro usually small as if house in something the size of a salt shaker?
With the mounts I was referring to the Quality control & finer tracking control with higher level of accuracy…This I would of thought the pro model more worth of purchase due to these attributes was all.
As for what type of photography…MMMM…I was going to be happy with wide feid on an ED80mm and use the Newtonian for Planetary type stuff. I was wondering if the FL on that model was up to it though. Thought I better not ask to many questions….hahahahahahaaaa…LOL…But I am GLAD you brought it up:
Here is some shots of Planets with that scope…but then again I wonder how much of a gimmick it all is…as I cant find toooo many dedicated image pages as I can with other scopes out there:

Honestly…Thanks heaps for chatting…I need all the help I can get, Thanks for your concern about me getting carried away and all that…I’m just that kinda guy J and although sometimes it lands me in trouble only to be more confused than when I started, I usually end up with a much better idea of what I am getting myself into. Just consider me one of those complicated guys that has to do everything the hard way.
I am a bit thick, but it does not worry me,,,its why I seem to be able to hit my head against a brick wall twice as long as most, even though I only get half the answers. I even have to stare 10 times longer into space to find what others find easily…We all learn differently. But WOW,,,I’m starting to enjoy reading stuff I don’t understand like when I stare into space in awe…eventually it will sink in…I know I have met some really interesting people.
Thanks again Robin…I will check out your methods for sure!!! Please let me know if there is anything else about this post you don’t understand. I will only be to happy to clarify.
Dave
PS…For anyone else…
The Other suggestion I found hard to understand was about replacing the “Size of the secondary” In to match the size of the cameras sensor chip. Once again, my thoughts & misconceptions have been also noted, but it’s no biggy. I have a book underway from Amazon, or I’ll simply find out as I continue to research these finer points…I’ll try to slow down as you say…but don’t really feel out of breath at this stage.
