    Just a clarification on the GPS and what it actuality does...

    All of them download the date time and location and enter that into the scope for you... this saves you maybe 10 seconds over the time it would take you to manually enter that info into your telescope..BUT it is accurate and thus eliminates the garbage in garbage out situations we sometimes manage to accomplish...

    On the Meade scopes the GPS also will find North and point the scope correctly and also level the OTA so the alignment process can begin...

    The Celestron does not do this...BECAUSE the scope noes not have to be pointing in any particular direction and does not have to be leveled to begin the alignment process...

    Neither will self align... (the Meade Light Switch scopes do self align BTW)....

    You have to pick your own alignment stars and center them in the eyepiece of the telescope and that process is basically the same with both scopes...

    The GPS is a convenience and nothing more in my opinion...worth a grand total of 20 bucks ...BUT yes my two Celestrons both have a GPS but My Meade does not..and I honestly do not miss it when I use the Meade...

    Your are correct in that aperture rules for visual use and do not believe anyone who says it does not... so you will not gat any arguent out of me on the difference between a 10 11 or 12 inch scope EXCEPT to say the ...difference between a 10 and a 12 sure is not going to knock your socks off its there and you know it is there so why not go with the 12....

    Now having said that...I run a CPC1100 pier mounted n my observatory...I shopped and tested maybe a dozen individual Meades and a dozen individual Celestrons over a 4 to 5 months period before I wrote the check for my CPC...

    Optically every darn scope was "almost" identical BUT on average the Meades ACF optics honestly was a hair better BUT only at the extreme edge of the FOV...the center 90 percent of the FOV were basically identical...PLUS optically there was more variation between the dozen individual scopes of both manufacturers then there was between the two brands.....Overall I would not rank any single scope as being bad nor would I say any one individual scope was fantastic...

    Now the Mounts... In my opinion the Meade Lx90 12 inch scope is severely under mounted...The 10 inch Lx90 is fine however... The Lx90 mount is NOT as stable/strong strong as either the Lx200 Mounts or the CPC mounts...which are both a cut above the Lx90...

    I boiled my choices down to either a 10 inch Lx90 (I eliminated the 12 because of the above) ...or a 10 or 12 inch Lx200 or the 11 inch CPC...Then I looked at what each would cost me... That eliminated the 12 inch Lx200 as it was significantly more then the CPC and much bigger then the Lx200 10 inch scope...

    As I noted I do have 2 Celestrons as well as a Meade...and the other reason I went with the CPC was frankly not a very good one...I just like the CPC hand controller a lot more then I do the Meades Autostar Hand controller... Both work fine...its just that I personally find the Meade requires a ton of scrolling thru the menus to do simple things that can be done with 2 buttons on the Celestron HC... This is very minor since once you get used to suign the Meade it becomes second nature...

    Bottom line..its you money any of these scope will do BUT the big Lx90 (12) is just not mounted well enough for even visual use as far as I am concerned...and extremely under-mounted for AP...

    Just my own opinions but based on a lot of "testing" of individual scopes over a few months....

    Clear Skies...
    BTW... I have more money invested in my eyepiece case then I do in the Telescope..so you better take the cost of eyepieces,diagonals,focal reducers, etc into account when you set a budget... LOL

    Just a slight addition. With the Meade LX200 (and I presume the LX90) if you are doing an auto alignment the telescope chooses the two alignment stars itself.

    This is not necessarily a benefit since the telescope just might choose stars which you don't know how to find.

    So last night my LX200 chose Arcturus and Dubhe. It slewed the telescope pretty close to Arcturus first, I centered on it and aligned, then it slewed to the vicinity of Dubhe and I centered on it as well. But if I didn't know (or couldn't see) those two stars I'd have had to tell the telescope to choose another which I could (hopefully) identify and see.

    It's my understanding that the Celestron has you choose the alignment stars and then slew to them. I'm not sure which I would find preferable - but I've heard most like Celestron's method a bit better.

    FWIW

    OLDCUSS...

    I though that the Meade also lets you choose your own alignment stars (I know my Meade Gem mount that uses the Autostar HC sure does) the Celestorn can use both auto and manual 2 star alignments...(you still have to pick the first star however) as well as skyalign that uses any 3 bright stars...

    Not much of a difference between the brands the only thing certain is that the second star normally is behind some tree ...with the auto methods...

    I've only tried the Auto align approach. It would not surprise me at all if you're absolutely correct.

    Well I took the jump and went with the Meade afterall. As the specialist told me with the ACF on this scope you can use it for AP. They did end up giving me $200 off the scope and I get the free 24mm eyepiece and the 2" diag. And with free shipping. Getting it Wednesday! So I am looking forward to this. Thanks for everyones help, and I will keep you all posted on the turn out with it.

    Just to clarify a little? ACF is a help for photography but is not what makes a telescope suitable for AP.

    There are a number of different ways in which one may choose an outfit for AP - depending on your chosen methods and priorities.

    Your telescope will have excellent optics and a mount which will inhibit your ability to do AP. ACF will make a marginal difference.

    That said, I think you made a good choice. Most of us end up not doing AP anyway and, as I noted before, there is some pretty good photography done using a telescope very much like the one you've chosen - it just takes some extra adjustment and effort and an acceptance that you have an AZ mount rather than an equatorial one.

    But the "specialist" who told you that ACF means that the telescope is going to be good for AP was flinging something at you that would not smell like roses and would originate from the tail end of a bull.

    Just to let you know, they are now shipping the LX200 tripod with these LX90's.

    No, he wasn't saying that ACF means AP, but will make the clarity alot better. But I could do AP with this scope if I decided to. But as I said in a earlier post. Its doubtful that I would do any AP with this. Or any others.

    Good. An eyes wide-open purchase.

    Personally, I think you're getting an excellent telescope.

    Both Celestron and Meade LX90-- LX200--ETX90) let you pick another alignment star if the one it slews too is blocked by a tree or a building. I believe on Meade scopes it is the scroll down arrow at the bottom of the hand controller.
