I thorougly enjoyed it too & I must admit there were parts of the program that made me chuckle, whether it was the parodies or Patrick being himself, a true legend & a great man who sadly will be missed.

A very sad day indeed, rest in peace sir.

& a pemanent empty wallet I guess......

I've just posted my first DSO's here although I'll shove the pictures on here too of M13, M57 & M51.

All single shots with no processing, 30 second subs at ISO 800 taken 23/7/2012

Thanks Matt I think my draw tube collar may be different to yours so it looks like I may be on the hunt for one of those too unless I can find a 2" adaptor to fit mine.

Who would think that getting a 2" adaptor for a Skywatcher would end up proving to be a bit of a nightmare.

I'll ring them Monday as they're closed till then, thanks for your help....

Thanks Jim it does indeed measure 57mm although I'm not finding anything on RVO.

Thanks Earl I've just measured across draw tube & the inner diameter is 54mm, although I can't measure the pitch of the thread so I'm guessing its an M54 thread. I'll contact modern astronomy & see what I can find out.

Normally the two inch adapter will fit like your 1.25" adapter does, looking at your first image it appears that the dovetails are not the same diameter, this would suggest that sky-watcher at some point have changed the adapters.

If I recall on my last scope the 1.25" adapter fitted into the 2" adapter which then fitted into the focuser. Can you see if that works, it is possible that the adapter on the end of the draw tube is not the standard one.

I've pretty much tried everything but it's not playing, I guess it might be possible that the adapter on the draw tube may not be standard. I've seen other 200P's but never really looked that closely at the focusers. The diameter of the chamfered edge on the 2" adapter is not only smaller but the angle is different too.

If anyone has a picture of a 200P focuser & 2" adapter they can post for me please that would be a great help.

That's what I thought but this doesn't appear to be the case. I've looked around online for one but I haven't come up with much.

It's the standard Skywatcher focuser with an after market dual speed fitted.

I took the 1.25 adapter out but it's slightly to big for the 2" adapter.

Hi everyone.

I brought my 200P second hand a while back & it's a great scope. In the specs it says it can use 2" EP's but mine never came with the adapter. So I have been looking around & was told that one of these would fit;

However after its arrival today I'm still left head scratching as I'm unable to do so, Am I missing something?

Below are some pictures of the 1.25" & 2" adapters together.

The 2" adapter in the focuser ring that screws into the focuser tube.

It looks like it should be held in place with just thumb screws as the only thread is on the inside of the tube (I'm guessing for filters)

If anyone can help then it would be appreciated thanks.
