  1. It looks like it's about the same as you're seeing in SS6.

    In SS7:

    17 Cyq / HD 186858:
    Under 17 Cyg it says it's secondary is 25.9" away.
    There are two different stars listed under HD 186858 - one very close to 17 Cyg, and the other a short distance away.

    Mizar:
    The description (words) says the separation is 14" in one place, 11.8" in another and at least 500 AU in another.  The basic information (numbers) lists separation at 0.8".

    If you're thinking about buying SS7 in the black friday promotion, I'd say it's worth it overall, even though the catalogue errors are probably not much (any?) better than SS6 - I moved from SS6 to SS7 when it first came out and I like a lot of the new features very much.

    Finally went to the opticians today to have an eye test, which confirmed my suspicions that I have developed mild astigmatism - 0.5 in my left (dominant) eye.

    Your astigmatism while looking in an eyepiece might not be quite the same as that measured by an optometrist as part of a normal eye test.  That said, these differences only usually get noticeable at more severe levels than your 0.5 - so a 0.5 dioptrx will probably be fine.

    was hoping to save up for the Svbony 8-3mm zoom but I guess it'll have to wait

    The smaller the exit pupil the less astigmatism shows up.  In the 3-8 zoom the exit pupil will be small and I don't think your astigmatism will be noticed.

    Your Parka looks very stylish! We all got sent to school during Winter in the 1970's wearing this hideous outfit and bright orange on the inside!

    Did your school have a music practice room?
    It's not hideous, it's lovely. Would I lie to you?

    (Sorry to anyone that 'gets it' .... 🚪)

  4. I'm with John, it looks like an Askar 185 to me - orange and all.
    I don't think it's a SkyWatcher only room - there is a ZWO display at the back, so I don't see why there can't be an Askar one on the left.
    Interesting stuff, whoever makes it.

  5. I record my observations into a digital voice recorder - so I can stay at the eyepiece for longer periods and not forget to record anything notable.

    I sketch with pencils onto paper - not very artistic but it records the positions and features that words alone do not capture.

    The next day:
    I write up the voice recorded notes into SkySafari observations.
    I store the digital sound recording(s) onto my cloud storage - and add a url to them in the relevant SkySafari observation notes (as text - it's not clickable - but it does link them together).
    I photograph my sketch(es) and store them on my cloud storage - again adding a url to them in the SkySafari observation.

    Being able to add files as attachments to SkySafari observations would be so much better - but this is as close as I can get.

    but at considerable cost I would imagine.

    The Askar 140 is a 140mm f/7 ED triplet and is £2,098 from flo.  Not sure how much this adjustable section added to arrive at this price - but it seems pretty good value overall.  Subject to it actually working well, and the optics being good, etc etc.....
