I've upgraded my focuser so have a Skywatcher Dual-Speed Low Profile 1.25/2" Crayford focuser for sale £70 delivered to UK only.
Bank transfer or Paypal F&F preferred.
I just installed this Lacerta 1:10 Micro Transmission focuser on my 8” Skywatcher Dobsonian. It is a direct replacement for the stock focuser and works extremely well. I was surprised at how easy it was to install! Ordered it from 365Astronomy and got fast shipping.
I've decided the Skywatcher dual speed focuser is not up to astrophotography, there's too much play in it, I've tried tightening it up but it still flops about. My sweatheart has asked me what I want for my birthday/xmas presents, as the are very close together I don't mind just the one. So the question is which should I go for, either the Baader Diamond Steeltrack or the Moonlite CR2 dual speed crayford which with the installation kit will be quite a bit more in price.
Two questions if I may.
1. Can the three screws marked by yellow arrows in the picture below be used to mount a second finder shoe on the C11 EDGE HD scope, permitting both a straight through and a right angle finder to be fitted?
2. The EDGE has field flattening optics inside; is the distance from the visual back to the chip critical, or by making adjustments to the position of the mirror to achieve focus on a chip say 250mm away from the visual back mean the field will still be flat at that distance?
