Bobs Knobs

I am awaiting delivery of Bobs Knobs for my 200p Dob.Can anyone tell me if the replacement is a straightforward business?I can see that replacing the adjusters should be OK but what about the retaining screws-can you just take them out one at a time with impunity,or is there a spring likely to fall inside?Do I have to remove the primary to do it?If so,how? All this fuss and expense because of cloudy skies!!!!

Dead easy - I did mine one at a time, but made sure the OTA was at an angle ... just in case.

Just ensure you don't get them crossthreaded.

that's the way to do it take one screw out then put one knob in full instructions are supplied even I could do it

Was a doddle on our dob. There were some simple, clear instructions included, it was easier than I thought!

Would also recommend to always make sure you have the tube pointing sideways, just in case anything drops and hits the mirror.

I still haven't worked up the courage to get (and fit) a set to my 6SE ...

I've made my own for my scopes. as others say, do one at a time, scope at an angle, recollimate (which is now a lot easier) and you're good to go.
