    9/20/2018 3:13 PM Baader 2" ClickLock eyepiece clamps
    I would like to buy a Clicklock for my Skywatcher Startravel 120 - can you confirm you have a model that fits this focuser? Danke.

    Answer rated: 0
    We do not have every telescope in stock, and sometimes the specifications change - so, if the thread isn't mentioned in your telescope's manual, it is the best if you measure it yourself.
    We have described how to do it here: https://www.baader-planetarium.com/en/blog/clicklock-clamp-for-your-telescope/
    Or asking a dealer who sells SkyWatcher telescopes to get the specific answer.

    9/18/2018 1:28 PM Baader Micro Guide eyepiece with Log-Pot illuminator
    I have the eyepiece and illuminator above. The 2 batteries in the illuminator are dead. Can you tell me what size batteries are required for the illuminator.
    The "dead" batteries in mine do not have any identification on then at all.
    Best Regards
    Andy

    You need 2x SR41 or LR41 Batteries. Both do work.

    9/17/2018 3:08 PM Baader T Adapter (BTA) for SC and MAK Telescopes (T-2 part #21)
    I have purchased the Alan Gee MkII and need to adapt it to my 2” Moonlite focuser which is mounted to my GSO RC8. It looks like I will need items 16 and 26 to do this. Where is the best place to order these from to be shipped to the states? I have various spacer rings to use with my Altair Astro 183C PROTEC camera that had 17.5 mm flange distance. The AG was purchased from Agena AstroProducts. Thanks, Tim

    Answer rated: 0
    Yes, you need the parts #16 (# 2408150) and #26 (#1508025) to mount the Alan Gee in a 2" eyepiece clamp, and in addtion some spacers to reach the desired distance between sensor and Alan Gee.

    For purchase in/delivery to the United States, please contact our distributor www.alpineastro.com.

    9/16/2018 4:37 PM BACHES Echelle-Spectrograph
    I am considering the baches spectrograph to be paired with a plane wave CDK17 which is f6.8 - i see from the manual that there is significant loss of flux with this configuration - is there an extender lens that could be used to offset this effect and what might be the impact on back focus if so? thank you

    Answer rated: 0

    In order to achieve a focal ratio conversion from f/6.8 to f/10, the distance between barlow lens and the entrance slit of the spectrograph should be approximately 48mm.

    Than means the barlow lens can be mounted directly onto the spectrograph. The additional backfocus can be gained, for example by using a M68 extension tube.
