    Ian,
    I was using it with a camera no issue.
    I am using a diagonal with 2 spacers screwed into to the eyepiece barrel to achieve focus for visual.
    I was not aware this was an issue with some refractors.
    That’s a question people should ask when buying for visual use as I suspect it won’t be mentioned in the specs!
    Regards,
    Jack

    Giovanni,
    You have understood correctly.
    So, I am using spacers to achieve focus.
    I was not aware this could be an issue with some telescopes!

    Grant and Paul,
    Its a Paramount MX with a 70 star T point model.
    I use http://www.thinkman.com/dimension4/default.htm to set the clock.
    Question for Grant: Are you saying that if I change my lat lon location in TheSkyX I have to do another T point run?
    Regards,

    A conundrum Google Earth says 51.59 36 0.60 77 The SkyX X says 51.37 45 0.36 27.
    Question: If TheSkyX co ordinates are wrong would that explain why the target is not dead centre in the field of view.
    It has a T point model.
    Which one is correct?

    Sheridan,
    A later version 10.2.0 or newer SkyX software needs to be installed this works with Windows 7 or 10.

    Andy and Robin,
    I have 2 slits and slot supports and changed from the 35 to the 23 micron slit.

    It appears the latter is faulty.

    Question, Would the wide slits be useful?

    Peter and William,
    Because the computer was displaying a black background, I could not see the text in the status bar.
    So, in Personalisation settings change to a standard Microsoft picture.
    All working.
    Thanks for you help.

    Robin,
    ‘I recall you have a remote adjustment, could this have been preloading it causing premature wear’?

    Are you advising against motorising the micrometer ?

    Robin,
    I have released the collar. When tightened then slackened a fraction of a turn the micrometer is easier to turn.
    It may be worth an overhaul as you suggest.
    Thanks for your advices,
    Jack

    Robin,
    It became increasingly tight over time.
    From your photos and comparing with the other Lhires the collar looks engaged.
    I will overhaul it as you suggest.
    Question 1; What lubricant should be used and is there a risk of it getting on the grating?
    The remote adjustment is the motorised collimating lens.
    Regards,
    Jack
