Skyliner 200p Goto Conversion

[Lowen22 17]

Hi,

Does anyone have any experience converting a Skyliner 200p dobsonian (Non Go To) into a Go To telescope?

Can this be done?

Any help is appreciated.

It's a bit too costly to do really. If you google "Servocat" and "Argo Navis" prices you'll be gobsmacked lol. It's really only worth doing on very large dobs of 18" plus. I don't know of any cheaper kits available.

A more cost effective way is to mount the tube on something like an AVX or better still NEQ6 Pro/AZ EQ6 GT. That'll cost around £800 to a grand new (or half to 2/3rds of that second hand). It's a bit too big for an EQ5 - but the shorter 200P tube (fl = 1000mm) can be used for visual observing on this mount without too much hastle.

If you do go down the EQ5 route, it's possible to add stepper motor drives and use an Astroeq to make a very capable goto system, but as Brantuk says, the 200P is a bit too much for imaging on an EQ5.

Maybe its best to keep this scope as it is then.

The only other question I have is, can I attach some form of tracking device to the scope? 

Thanks for your help.

The device you're looking for is called an equatorial platform. I'll have to leave it for others to advise on which brands are best though.

Ahh yes - nice one Ricochet - it's often called a "barn door tracker". It's not a conversion - more of a platform that you stand the dob on. They can still be expensive though:

I've also dug out a build design from my local group for you if you fancy a bit of tinkering yourself (could do it considerably cheaper). One of our astronomers made a very nice little dob tracker/eq platform himself (for around £100 iirc) and there's plenty of very interesting references here:

That's more like it!

Thanks, will give this a go over summer months.
