    Default Eye piece advice for 12" LX200 sought.



    Hi. After 10 years of waiting I am ordering the 12 inch from Astronomics tomorrow morning. I am extremely excited. I wonder what eyepieces to get, though. This is an f10 scope and I am under the impression that it doesn't take 2 inch eyepieces.
    What eyepieces would work well with this scope and how can I use 2 inch eyepieces with it? Should I even try or am I trying to make it behave like a dob?
    I will be doing planetary viewing and seeking out my beloved DSO's too.

    Yes it does take 2 inch eyepieces you will need to order either a 2 inch visual back-- or better-- a 2 inch SCT diagonal that screws on to the threads at the back of the scope.

    THIS IS A BIG TELESCOPE! Almost will need two people to safely setup -- maybe-- depends on if you are Hulk Hogan.

    Wonderful scope -- be sure to read the manual TWICE-- and play with it inside the house to learn the hand controller before you take it out in the dark.

    Do all of the setup described in the manual like Training the drives, and calibrating motors-- etc etc.

    Sure you can use 2 inch eyepieces like Joe mentioned above...BUT you will need a 2" visual back and a 2" diagonal..(the visual back "sometimes" comes with the diagonal..

    I run a CPC1100 and all of my higher power (under 25 mm) eyepieces are 1.25 inch format and all of my lower power (over 26 mm) are in 2 inch format...

    I personally run a 2" Denkmeier p/s diagonal..

    I agree with Joe about the size and weight of the Lx200 12 inch scope... I'm 67 and if my CPC1100 was not pier mounted in my observatory I would be physically unable to lug it outside by myself...and it is smaller and lighter then the Lx200 12

    Great scope however for those who can pick it up LOL

    Thank you all very much for the great advice. I am not really worried about the weight. I press about that much in the gym and I have some ideas about transport to make things easy and safe.
    I did talk with the nice man at Tele Vue Optics who suggested that I buy a 24mm Panoptic, a barlow and a 31 mm Nagler type 5. That is a serious chunk of change. I waffled over the telescope for 10 years so I am not about to buy premium eyepieces without some advice.
    It comes with a 26 mm series 5000 Plossl. All I have in my little collection is an Orion 25mm Plossl, an Orion 9mm Plossl, an Orion 32mm Optilux (my favorite!) and a 2x Shorty Barlow.
    To do this scope justice I think it is time to upgrade.
    @Joe I really appreciate the "whoa boy!" I will most definitely learn the scope before taking it out. This thing is about 1/4 of my year's take home pay (I am a waiter.) I take it VERY seriously.
    @Bob I will be searching for the 2" visual back and/or diagonal as soon as I post this. What two eyepieces would you say you use the most?

    Here is the "general" procedure for setup for these-- some features may or may not be present depending on GPS or no GPS and what version of the firmware is loaded-- here goes:

    1. Turn the scope on and execute a Calibrate motors using the same power supply you will use outside at night.

    2. Train the drives -- do this about once per year.

    3. Enter SITE, TIME. and DATE, and Daylight Savings equals NO right now.

    4. Outside at night Calibrate sensors on Polaris- if you have this feature do this about every 4th time you take the scope out.

    5. Do an Automatic 2 star alignment and center both stars.

    Nothing wrong with Tele Vue eyepieces ( and I mean absolutely nothing) and I even own 2 Panoptics ...I do not like Naglers as my old eyeballs have to shift all over the place to get to see then entire FOV with them...its uncomfortable for me..(I'm one of the few individuals who have this problem) But I still advise you to find a local club and "barrow" a few eyepieces to try at a star party and you will have no problem with guys wanting to see their eyepieces preform in your scope believe me...

    The Good news is that at f/10 your scope does not need real expensive eyepieces to preform very very well... Orion Stratus.Baader Hyperions cost 1/3 of the price and will work just fine as will most eyepieces..

    I use my 24 and my 31 and 35 mm eyepieces more then I do any others all of my lower powered eyepieces are 68-70 eyepieces. heck with the Denk diagonal I can go all night just just the 35 mm (it is a Pan) and get 48x 80x and 160x ... Toss in the the 24 which yields 70x 116x and 230x and there is not much else I generally need...

    Hi,

    Scopes will come and go in your life, but you'll end up keeping favorite eyepieces.

    Start slow and think in increments (double or half). With a 26mm coming with the scope (I think Meade recently changed from the 5000 down to the 4000 series, both are OK), you’ll get about 115X; a good all round choice. Want more power, I would go up to a 12-15mm and you have 200-250X. If you have really stable skies and want more power try something in the range of 7mm and you're at 428X. The most I have ever been able to use on my 10” was 350X and then only twice in 15 years of having 10” LX200’s. My guess it that over 350X on your 12 will be on nights which are few and far between (unless you live on an Arizona mountain top).

    For your DSO's go the other way. A 55mm gives about 50X and in a 12" SCT that's a great view and you won’t need much in between that an your 26.

    Now I know that there are folks out there who will tell you why they have 29 different eyepieces, but if you have only one scope 3 or 4 will do the trick for just about everything. I have 10 eyepieces (mostly TVs) of which I use 4 on 2 scopes 90% of the time.

    Price does not always equate to improved view. Definitely go to some local events and try out what others are using. Huge apparent fields and long eye relief are not for everyone. My favorite planetary eyepiece on my 10" LX200 is a TV15mm PL which isn't made any more. For general use and DSO's I like the Meade 26MM 5000 which came with my scope. On rare trips to dark sites I like the TV 55mm PL. My scope is permanently mounted so it stays in one place 99.5% of the time.

    2" eyepieces are fine but don't by themselves add much just because of their size.

    You don't need to be in a hurry for more eyepieces; take your time so you don't waste money. You can find a pile of eyepieces and sets for sale on Cloudy Nights, sometimes for 25 cents on the dollar. There are lots of things on my wish list ahead of $500 eyepieces.

    Glad to hear you work out because that 12" is heavy and awkward. The use of any telescope is directly proportional to how convenient it is to use. If using your scope becomes a major task, then eyepieces don’t matter in the least.

    Most of my work is now imaging so I replaced my Meade focuser with a Moonlite unit. Consequently, I have a Meade screw-in 2" diagonal I would be willing to part with if you're interested.

    Hope this helps

    The Televues are great eyepieces -- however with your SLOW telescope-- you can use a mid-priced eyepiece like the Hyperions and get great views.

    Take a look at the Hyperion line of eyepieces:

    Price sure looks a lot better than the Tele Vue. Well, I have about 2 to 3 weeks before that sucker gets here, drop shipping from Meade, so I have plenty of time to choose. Of course, I'm also broke after buying the scope so it will take that long to be able to afford anything! . This is a good thing because right now everything from Binoviewers to eye openers to super wedges and Ethos eyepieces and blah blah blah..... it all looks good!
    I think I will wait till it gets here, take it out for about two weeks of "getting to know you" and then I will decide what to get. I need to calm down! Thank you all so much for the benefit of your experience so I don't have to reinvent the wheel.
    Clear skies and a safe and happy New Year!
