    Does frost like that mean you can turn off the cooling fan, on the camera? 🤔🤣

    Indeed, the JWST is designed to look outwards, not have cameras strapped to it to take selfies!👍

    It's the SW Polar Scope for the EQ5 Deluxe mount.

    It's the ZWO ASI 120MM mini.

    My polar scope reticule looks something like the photo below, sitting at an angle. My question is, does it need to be perfectly aligned in the viewfinder, as in the bottom picture, or can it be somewhat offset, like in the top photo? 🤔

    DPD dropped this off in the last hour, courtesy of Auntie @FLO.

    Not that long ago, this would have been considered science fiction!😵🧐

    I'm almost certain those French guys were hitting the Fireman's switch, given the height they have to jump. Probably illegal to do in most countries, unless it's an emergency?🤔

    I was referring to the powers that be, rather than the public. Seems that there's many a toothless local and central government departments out there.

    Knowing about it and acting on it are two different issues.😧

    I've got an 8" Dobsonian and have used 375x magnification on the moon, very occasionally. Even with a F6 ratio on the telescope, I can tell you that at those magnification levels, the moon is very dim and you will probably see 'floaters' in your view. Contrast is very low too, even on a bright moon!

    Are you sure that's not been fitted by the Probation Service?🤔😂

    We'd probably get better observing conditions, if we were on the surface of Venus!🤬
  15. Ian McCallum
    That's what I meant.

    Correct me if I'm wrong, but once you've set up the guide scope and camera on a target star, then using PHD2 should keep the guide scope aligned by sending small "nudges" through the ST4 port to the mount? 🤔

    At this moment in time, I'm holding off buying a guide camera due to the weather. I've not even been able to test the motor drives yet, due to constantly overcast skies and rain.😡
  18. Ian McCallum
    That's better, thanks.👍
  19. Ian McCallum
    Either dead links or no images?🤔

    I'm thinking about converting a SW 9x50mm finderscope to become a guidescope, with the addition of an adapter and camera. My question is, can I use the existing finderscope shoe on the OTA to hold it, or would it require scope rings for the guidescope, etc, etc.?🤔

    I'm very much leaning towards the ZWO ASI120MM mini camera, with an adapter for a SW 9x50mm finderscope.
  22. Ian McCallum
    The mount doesn't have a suitable port, only the Enhanced controller does....
  23. Ian McCallum
    What did you have in mind? Can you give me an example, please?
  24. Ian McCallum
    Genuine rocket fuel, along with cauliflower and cheese sauce!🤣
  25. Ian McCallum
    I'm interested in learning more about the ST4 method, so I'm doing more reading up on it. It's all rather new to me, as you can probably tell.🙄
