Hello,

I have followed threads to no end, researched my butt off and sought opinions far and wide and have narrowed to a few scopes.

I am considering the MN66, m603 and the TAL 200K. Of course at this point I am just stumped. I have no way to see any of these scopes in person and keep getting conflicting info regarding astrophotography applications. I want to use my Canon 10D, prime focus for shooting lunar, planets and start with some of the easier DSO's.

I realize that I am probably down to personal preference and that all of these are good, but please thrwo in your input if you have it.

Mount is an Astrosky Dominator with a GM8. I have another heavier mount being built now that will be more precision and hold lots more weight.

I don't know yet if I'l use off-axis guiding or finderscope, but shoot an opinion on that too as regards to a specific scope. Obviously this brings in backfocus issues too.

As far as Mak-newts not being used for prime focus, I have been told that you can do it with low profile focusers, moving the primary or using the 2" OCS. I have seen the results and they are good.

My heart tells me to get the MN66, but the size of the others is tempting as I would transport this and wonder if balancing is easier?

My goals are astrophotography, with a strong background in regular photography. I am not as interested in cataloging objects as i am in getting crystal clear photos with high resolution. Contrast is an issue but can be adjusted later. I am sort of assuming that with the two slower scopes I would use a focal reducer for photos. Possible CCD in the future but not now.

Thanks for any input you can give to help out.

-Also, I would most likely be looking for used . . and scope can be stored in outdoor shed so cooldown isnt so huge.

Hi Jeff, first of all I would say if you're heart is with the MN66 then go for it. If I'm not mistaken, the aperture of the 603 is equal at 6" but the Tal is 8" so if you're main goal is to produce crystal clear photos the size may not be the issue. What needs to be considered and again, if I'm right, the MN66 has the shortest focal length so if you want to shoot dso's as well it may be your best choice. Transportation at 6" shouldn't be difficult unless you mean air-travel of course..Suppose prime-focus photography is not possible with the MN66 I think you could mount_as you say_a low-profile focuser and have an extension tube for projection-work on Moon and Planets, which will also solve backfocus issues in using an off-axis guider. In the end I think the MN's 'bussiness end' will be more easily adaptable for photography.
Hope this helps a little in further narrowing down your choices..
