Is the Skywatcher Skyliner 250PX Dobsonian Any good?

Recommended Posts

Welcome to SGL

I think you might get better response to your question if you post it in the "Getting started Equipment help and Advice " thread,

sorry i can not be of help with the telescope question,

The Skyliners are decent all-round telescopes. They come with two eyepieces that are good enough to start with. The base is heavy and the tube is huge. What 'non-decent' scope did you have? What do you like to observe - deep-sky, planets, double stars? A bit more information might be useful.

Hiya.

I'm sure that if you search the site you'll find plenty of recommendations for this scope. In short, though, it very much depends on what you want to view, how able you are coping with the weight and size, and what your budget is for eyepieces ...

Perhaps if you offered a little more information ... ?

I have the 300p FlexTube. All I can say is try and see one before you buy. Do not underestimate the size of it.

There was a poll on here a couple of years back on the most popular scope for obervational astronomy balacing performance potential with affordability and practicality and I seem to recall that the 10" F/5 dobsonian, such as the Skywatcher Skyliner 250PX was the winner.

I've owned one and used other peoples and found it to be an excellent scope. Probably as much performance per £ spent as you can get :icon_biggrin:

The cons are that the solid tube version needs some storage space (the flextube version is shorter when stored) and obviously you need to find your own targets to observe so a good sky atlas and some patience is required.

In short, a very capable "first" scope indeed and one that could provide a lifetimes enjoyment, and often does !

Hi Simon....It depends.  if you are looking for a good all round visual scope then a 250 Dob is about the most that the average person could (should) lift and will give you the maximum aperture for the buck. There are some expensive and superb lightweight truss Dobs that are bigger and get around this but as a rule of thumb it stands.  Having said that it comes with several caveats:

1.  If you want to progress to serious photography a Dob is not going to work.  In the words of some wise AP hands on this forum, "For observing, aperture is all; for imaging, the mount is all”.  Your mount has to be able to track stellar movement very closely to get any type of worthwhile image. 

2. Check it fits in your car, at some point you will want to take it to a dark sky site.  If it doesn’t, as John has advised,  a truss dob is the way to go.

3. If you are content to find your own way around the sky then its a great way to widen your astronomy knowledge and adds to the satisfaction of finding your target.  If not, you need to look at a goto scope - this will double your budget though.

4. If you are interested mainly in planets or lunar then you could get by with a smaller scope and save some money for additional eyepieces.

In the end it is a choice that only you can make but lots of people here can help with advice.

Good luck with your eventual choice.

John

I have had my Skywatcher 250mm collapsible dob now for about 10 years, and out 2 or 3 times per month with my astronomy club, doing presentations in schools and scout/guide groups

Find easy to transport and store, as folds down when not in use

I have additional assortment of eye pieces as well as  2 X Barlow

A little trick

The hard plastic cover, has a removal small cap, which fits over the non-removal cap

Tape a bit of Baade visual film on the underside of the small hole, and fit over top of the tube, and can use for solar viewing

Make sure spotting scope is removed

Talking of spotting scope, get yourself a right angle spotting scope, if viewing objects almost overhead, do not have to lay on the ground to align scope with spotting scope

Have attached pic for of mine with right angle spotting scope fitted

Pic taken at a club public viewing night

I have the 300p GoTo Flextube and it's a great scope, but heavy! The 250 would be lighter ( although not as bright  for Deep Sky fuzzies) and the Flextube version much easier to store/transport.

My Skyliner 250PX has the Skymax GoTo built-in. I tend to use my Skymax 127mm Mak. more often, but the Skyliner is a close second. I have a Mazda MX5 roadster, and there is no way that the 10" Dob. tube, or the 53" diameter base, will fit. The base, and collapsible tube, are relatively easy to carry, as 2 parts, for about 10 yards from my garage to my patio. It is a challenge to go up or down a flight of stairs; you have to use a "wide knee waddle" to avoid bruised shins.

The end of the tube describes a large arc when tracking or slewing to objects close to the horizon, so, with the additional observing chair, you need plenty of clear space around the base.

I've had the Skyliner 200p for some years now and wouldn't hesitate to recommend assuming that the size is manageable for you.

But I would also agree with the guidance on the RACI finder, and I would also get a telrad or Rigel plus some sort of adjustable chair (ironing chairs and drum stools are cheaper alternatives to proper observing chairs). These transformed my observing experience.

The Skyliner 250PX Dobsonian I owned gave me superb views of the planets but sadly it proved to be too heavy for my bad back.

I consider it superb value for money given it's performance.

And it can be equatorially mounted at a later date ..... (this is an 8")

However, with the GP-CAM V2 and Sharpcap live stacking, I can "see" beautiful colours in M42 (Orion) & M57 (Ring) nebulae. An EQ mount may be better, but for occasional use, the 10" Dob. is fine.

On the back of how good the 6" and 8" versions are that I've owned, I'd say it's probably the best sub 500 quid scope you could buy for pure visual observations of deep sky objects. 

The only down sides I can see are:

1) it's a relatively big scope so factor in transport and carrying the thing.

2) Large apertures need more cool down time, and better seeing conditions to perform their best. 

Great scope, just also consider the 200p f/6 Dob, and some nice eyepieces instead for the same price. Either way definitely budget for replacing the 10mm eyepiece that comes with these scopes as it will improve high power views no end.

I've heard it's not as forgiving as a 200p or 300p of low quality eyepieces. 

Never owned one though, so happy to be corrected.

Yep you're right, the faster the optics, the harder they are on lenses. The 10" is an f/4.7, the 8" is f/6 and the 12" is f/5. The 8" is the kindest on lenses as it's a slower f/6, but even with the 8" I would still buy better lenses than the ones supplied as soon as money allowed. The supplied lenses are really just to get people going.

200p is worth every penny. A truly wonderful scope.will do most things you ask of it and not too heavy. It may well be the only scope you'll ever need .

I know I won't be getting rid of mine.buy some decent eyepieces and your away..maybe the best value out there. IMHO. Hope this helps.

Paul.

I've got a 8" 200P F6 flextube Dbobsonian - all the advantages of 8" solid tube, but easier to store, transport and move.

      Just wondering what peoples thoughts are on the pro's and con's of the different types of mounts out there? Do Dobsonian mounts have issues on non-flat surfaces (like a garden) or can Equatorial mounts ever have issues getting out of line too easily?

      Very happy with it! Wish the sky were clear, but as we all know, when we buy astro equipment, it's cloudy! Argh!
      The telescope was collected from David Lukehurst at noon and then we travelled back to Cambridge. 
      John Nichol primary mirror: 37mm thickness, Suprax. Hilux coated. Optics 1/8 PV wavefront  1/27 wave RMS. Strehl .95. Secondary mirror: 62mm MA.

      Hi,
       
          Looking for a 12" DOB (or larger) which can be transported to Prestwick, Ayrshire. Any brand, as long as the telescope is optically sound and in good working order. I'm a reliable buyer who has bought and sold on this site before.
       
      Thanks,

      Hi all,
      Last night was the best night of astronomy I've had in my short time delving into this passion. It was simply incredible. Fortunately my dear friends the midgies have departed Scotland for another season. This means I can now stand at the scope without ingesting a lungful of tiny biting insects and concentrate on what I am observing. Always a plus!
      Two nights ago I went to my local dark spot with my 200p SW reflector. It was wonderful. LP map shows Bortle 4, but I would actually say it was a 3 or possibly a 'bright 2' when the lights go down a bit in the wee hours.
      Last night, I took the 20" dob and parked up. I am finding it easier and easier to move this beast around, but it's still a little bit of work to set up at the end of the day (literally). It can't all be so easy!
      I'm fairly new to astronomy and my scopes haven't seen a huge amount of use. After several failed attempts to get the GOTO working, I finally sussed it last night. It was just a few simple things really - small errors on my part such as a misplaced washer which blocked the azimuth from using its full range of motion, combined with a limited view at home which prevented me from doing a successful align. A huge relief to get the GOTO up and running, but I now feel a bit like I'm cheating!
      I don't feel guilty enough to not use the GOTO however😁 Frankly, it's brilliant and was putting objects bang in the centre of the EP.
      I arrived about 6pm yesterday so plenty of time to set up. I left my counterweights at home and thus ended up strapping a small vinyl bag of tools and tyre jack to the underside of the mirror box with a tie-down. Worked really well actually! Can fine tune by removing a spanner or two.
      A few drops of rain blew through just before dusk but then rapidly cleared off, so all systems go.
      I tripped over the power cord after my first successful align. And then did it again a minute later after my second align! Will need to tidy that arrangement up or put some of my glow tape on the cable. Plenty of practice then doing an alignment, haha.
      M57 Ring Nebula for starters, I've been playing with my Baader 36mm aspheric quite a lot lately, I like the wide views. The Ring was fairly small through the 36mm but bright and crisply defined with an apparent faint blue tint. I then swapped to the 21mm Ethos and OIII which stayed in the focuser most of the night. 
      Next stop was NGC6960, Western Veil Nebula or 'Witch's Broom Nebula' which was mind-blowing. It appeared as a silvery apparition which threaded right across the sky and extended well past the FOV from the 21mm Ethos. Scanning along its wispy tentacles was amazing. There's something unnerving about viewing it, it gives me goose-pimples, just otherworldly. The Eastern Veil and Pickering's Triangle in the central area were also clearly prominent, albeit slightly less luminous than 6960. The Veil was also clearly visible without the OIII, but with much more 'background noise', i.e. stars competing for attention.
      Following this, I slewed over to the Cocoon Nebula, but only saw a very dark lane practically void of stars. That was interesting in itself as it was so apparent by virtue of its darkness.. I don't know if I bumped the scope alignment of if I was just too impatient to punch another object in to the handset, but didn't spend a huge amount of time chasing it. In hindsight, I think I slewed to the wrong end of the dark lane. I'll find it next go.
      I then lined up on the Crescent Nebula which was easily visible, lots of fine filamentary details observable after some time studying it. A beauty.
      Next was Dumbbell Nebula which practically looked 3D through the big dob, just jumped right out at me. Another simply amazing sight. I spent quite a long time staring at it and could easily see the entire shape and structure extending from the 'Apple Core'. I remarked last night it looked like it was hanging inches in front of the scope. That's sheer aperture working I suppose!
      At the end, I spent some time just slewing around and having a mesmerising look across the sky, just taking in the depth and variable magnitude of stars that a big scope can display. I was already running on three hours' sleep from the previous night and by this time, I was starting to crash but was on a natural high. I crashed into the bed happily.
      Can't wait for another clear night with the big dob. I was a bit worried a few weeks ago that I'd bought something I didn't have the time or skill to fully appreciate, but getting the GOTO up and running and being able to rapidly slew to various objects really put things into perspective. My 200p is a wonderful, portable scope, but in comparison, 20" of aperture is simply a completely different level. It is like the difference between a small grainy 640px video and high definition 4k with the brightness cranked right up.
      Tonight I shall stay in, sleep well and dream about how much discarded glass is needed to cast a 36" mirror blank and how many years it would take me to figure it...
       
      Clear skies all

      Hello all!
      I just installed this Lacerta 1:10 Micro Transmission focuser on my 8” Skywatcher Dobsonian. It is a direct replacement for the stock focuser and works extremely well. I was surprised at how easy it was to install! Ordered it from 365Astronomy and got fast shipping.
