Webcam Focusing Advice

[littlebeagle]

I have a Skywatcher flextube 200p and a philips spc 900.

However I'm unable to get it to focus either on it's own or with a 2.5x barlow. It's like it needs to be even closer to the secondary mirror than the focuser will allow.

I did briefly read something about needing a barlow that would take it from a f6 scope to something in the 20's? Does that sound right?

I can focus on a flag that is about 1/4 mile away. I tried with the moon this evening and it wouldn't focus, unfortunately the clouds rolled in before I could try Jupiter.

Hi

This will be no help at all but I had the same prob with my 200P Dob the 150P no problem.

I gave up!

Im sure others will answer this better than I

Thank you for your reply, at least it's not just me.

I'd like to get it working as I'd like some shots of the solar system objects, in hindsight I dived in and got the camera without understanding what I needed to get it work.

Ok try this:) full credit for this idea goes to RikMcRae (i had the same problem and he suggested this to me.

remove the 2"- 1.25 adapter and uncrew the 1.25 part-remove the 2 little tension screws on the 1.25 part and put them somewhere SAFE! you really dont want to lose these!, rescrew it in from the underside, refit the 2"- 1.25 adapter and your good to go!

You will need a bit of sticky tape to hold the cam in place, but this will get you started.

There is other ways of doing this but they cost money.
