Skyliner 200p Goto Conversion

Recommended Posts

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.

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.

      Looking forward to receiving my 102MC in the next few days/weeks depending on supply. Does anyone have any experience, tips/advice?  Looks like a good grab and go particularity for planetary observation - interesting “next generation” mount.

      Hi,
      having started with a 130P on an eq mount.I wanted something with more light gathering on a alt-azimuth mount. I didn't want to go down the Dob route although that would have been a lot easier and cheaper.🙄
      So I have now got a 200P on a Skytee on a Manfrotto tripod.
      My question is why do all the pictures I have seen of this set up have the scope side mount rather than the top mount.
      Is it just a question of weight if you also add counterweights under the top mount? I understand the recommended max weight is 10kg per mount although some places say 15kg.
      As it is a lot easier to mount the scope on the top mount than the side one (I nearly dropped it on the first attempt) and it seems counterintuitive to have the weight of the scope hanging off the side mount instead of sitting on top of the top one.
      Thanks.

      Hi everyone,
      I'm completely new to telescopes and know nothing but I want to learn and I need some advice!
      I have a budget of £200 which I can't stretch. I really like both the Skywatcher Heritage 150p and SW Skyliner 150p which I believe has been along longer than the Heritage.
      I would like to take the scope out occasionally to dark skies (so the heritage would be easier to transport) but with 2 very young children at home the reality is that I will mostly be using the scope in the back garden.
      Obviously both scopes are 150p but come with different accessory spec (specs below).... please could someone advise which would give me the most bang for my buck?!
       
      Heritage 150p:
      Magnifications (with eyepieces supplied): x30 & x75
      Highest Practical Power (Potential): x300
      Diameter of Primary Mirror: 150mm
      Telescope Focal Length: 750mm (f/5)
      Eyepieces Supplied (1.25"): 10mm & 25mm
      Parabolic Primary Mirror
      3-arm Secondary Mirror Spider Support
      Red Dot Finder
      Wooden Alt-Azimuth Mount
      Collapsible/ Extendable Tube Assembly
      Weight Approx 7.5kg
      Supplied with Gift Box
      33% more Light Gathering than 130mm
      Skyliner 150p:
      Magnifications (with eyepieces supplied): x48 & x120 Highest Practical Power (Potential): x306 Diameter of Primary Mirror: 153mm Telescope Focal Length: 1200mm (f/8) Eyepieces Supplied (1.25"): 10mm & 25mm Parabolic Primary Mirror 0.5mm Ultra-Thin Secondary Mirror Supports 6x30 Finderscope Direct SLR Camera Connection Wooden Alt-Azimuth Mount with Accessory Tray 73% more Light Gathering than 114mm Many thanks!

      For sale is my beloved but now superfluous to requirements HEQ5 Pro for £650
      It's in a used condition as you would imagine. I've had it for about 4 years and found great success with this mount. Ideal for those beginning astrophotography and also good for visual users.
      I'm calling it "deluxe" due to the upgrades I've had done.
      - It's belt modified
      - It's had brand new bearings and grease
      - The backlash has been expertly setup 
      - It has the latest polar scope
      - The power port has been replaced with an aviation style port which is a lot more secure
      It'll come with the hand controller and at least 1 counterweight (if I can find the second it'll come with both). The polar scope cover has been lost. The counterweight is rusty as always. There is some marring on the counterweight bar housing as shown in the photos.
      It also will come with the modified power cable required also.
      Note: the power LED sometimes doesn't illuminate but the mount is still powered (please see the photo with the hand controller).
      Collection or local delivery within Northampton
