    Default Maksutov-Cassegrain?



    Well folks, the fever continues. I shared my new found hobby with my brother and he sold me his 130mm Konus Maksutov-cassegrain scope with a Meade GoTo mount, lumincon filters, Meade video eyepiece, camera eyepiece adapter, and a collection of multiple sized Plossl eyepieces. I'm in seventh heaven. As soon as I got it home I started to research it on the internet. He couldn't find any of the paperwork that came with the scope. I thought I could find info on the internet. I can't find anything on that particular model.

    Can anyone point me the the right direction or have any experience with these scopes? What is your opinion?
    I've already sent an email to Konus from their website (no good info there).

    He also sent my home with some books:
    *Ley, David H., A Guide to Skywatching
    *Moore, Patrick, Philip's Atlas of the Universe
    *T&J, Atlas of the Skies; Journeying between the stars and planets in the Discovery of the Universe

    Look out heavens! I'm watching you!

    The manual for the OTA probably won't say much anyway. Point the wide hole at the stars; look in the narrow hole.

    You might be able to find information on the mount separately, if you know what model it is.

    You are right. I misspoke, and I'm looking in the wrong places. I assumed the mount and the OTA were a package. Guess I should have done a tad bit more research first. I do want to know a bit more about other's opinions on the Maksutov-Cassegrains. I've heard more about SCTs than MCTs. I haven't taken it out yet. I'm going to tonight (I'm always afraid of messing things up) that's why I'm interested in knowing more of the specs.

    Dont know about Konus, but i have a Maksutov-Cassegrain from Intes-Micro, its a 180 mm and the Delux ver. its a exellent scope with
    high contrast images superb on Planets and DSO if you use a focal reducer
    Now i live in Danger Maksutov-Cass is much better then a
    Schmidt-Cassegrain.

    I have a MAK and a SCT that are identical in aperture. The difference between them is not that much. The MAK has a focal ratio of f/13 and the SCT is f/10. For any given size eyepiece the MAK has a slightly larger image than the SCT and the SCT has a slightly brighter image. The MAK has a small edge on solar system objects and the SCT on deep space objects; however, these differences can largely be mitigated through the proper eyepiece selection; e.g., the view with a f/10 SCT using a 20 mm eyepiece is essentially equivalent to that of f/13 MAK using a 25 mm eyepiece.

    A smallish MAK should serve you well until you want a bigger light bucket! I have 2 MAKs and 2 SCTs. The MACs are smaller but for most observing, I prefer them over the SCTs. You'll find that when you go for larger aperture, the MAKs will cost a bit more. Don't know much about Konus, but they did make some nice refractors a number of years back. I've never seen a MAK made by them. What color is it? I think their refractors were orange.

    Enjoy!

    The Konus is the blue one in the background with the bright blue neoprene "dew sheild". Still having trouble seeing anything through it though. I haven't had many chances to take it out since classes started back up. I'm planning to start fiddling with it again as soon as I sit for my board exam which should be sometime in mid January. Thank you for the replies. -Stacey

    From my own experiences:

    Positives: Your Mak should have sharp images with no color aberrations on planets and the moon. The cool-down time is fairly fast. You also shouldn't have to ever worry about collimation.

    Negatives: You might have some coma on brighter objects. You'll get some image shifting when focusing. Your Mak also wont be great for most AP.

    Hi,

    Is it the Konus model # 1796? I was google searching the Konus Maksutov and found a few links (which you may already have seen):

    a review:
    Konus 130 Maksutov-Cassegrain - Review

    Then I found many online stores with that Konus but I couldn't find a PDF or manual yet
