  1. Found this little review of the Aldi spotting scope.

    “I have one that I bought some years ago, not sure if the current ones are similar. Based on mine though, if you have ever looked through a decent scope then you may find it frustrating to use (focusing was tricky) and the view is very dark and 'mushy', which didn't help, but that said for £25 it's actually quite surprising how usable it is in decent light (towards the low side of the zoom range at least!) and if you really only can afford £25 then it might be ok, though I rarely used mine and bought a good compact scope when I could afford it, which was like night and day in comparison!

    I took mine to Titchwell and struggled on the lagoon on a dingy day, the birds all blurred together into a mass of grey fuzz and when the RSPB volunteer let me look through his Swarovski (admittedly like comparing a trabant to a ferrari!) I realised how poor my scope was... I didn't use it again. I had been happy to use it in good light on my local reservoir before that though, you just have to realise that these things are only £25 and you can't expect to use them how you would with a more expensive scope - checking out birds at great distance or in low light is going to be very difficult and frustrating.“

  3. Used a now discontinued Baader adapter to connect to the OTA. pity they’ve stopped making it as it comes in very handy for a number of scopes. Was intending to fit this focuser to a Cassegrain scope  but the drawtube was a bit too long so this ended up on Big Red and the Badder Steeltrack originaly fitted is now on the Cassegrain.

    Knobs are standard stuff bought from Amazon and eBay. Brass thunbscrews are getting harder to find now though. Just had to add nylon tips to the two large screws though. 

    I built Big Red a few years ago using Carton optics.
