Replacing the focuser on a Bintel Newt
The standard focuser on these scopes is, I think, a straight GSO model (the 2 knurled screws underneath - 1 for tension the other to lock) and 10:1 reducing. They are fine for visual but when it comes to imaging, and automating focus for filters, it is out of its class by miles.
I've had a look at the mounting block on the OTA. The focuser is held into it by means of a couple of grub screws and, of course, the mounting screws into the OTA are not the same spacing as a Moonlite - no doubt because the Moonlite arrangement is actually in a rectangluar pattern.
And of course, the mounting plate on the OTA doesn't have any screws by means of which the Moonlite could be attached. So it means a new baseplate as well as focuser. That probably means tapping new holes in the OTA and all the many problems that go with that.
I wonder if anyone else has pimped their Bintel Newt and in particulr the focuser. And what they did?
