Sky-Watcher Dobsonian telescopes provide good all round performance for observing the Moon, planets, Deep Sky Objects and nebulae.
The Dobsonian mount, popularised by John Dobson in the 1970s, is a simple and efficient method of mounting a Newtonian reflector.
Based on the Alt-Azimuth principal Dobsonian telescopes are fast and easy to set up. It is a box-type mounting which allows the telescope to pivot in altitude, while the box itself is rotated on a base in azimuth. The secret of the design is to correctly balance the optical tube and use materials that enable it to moved easily when nudged but stay in position when not.

I like this telescope, interms of its imaging it is all that I expected it to be and in my opinion, it represents excellent value for money.
It's a bit of a lump to carry about, even if broken down, I have clonked the finder scope a few times already!
The bit I am not so keen on is the 'stickyness' of its movements when aiming. Despite being fitted with teflon parts to ease this, movements are stiff and jerky. I wonder if there are lubricants that I can use on the 'turnable' that would ease this?

It does what it says on the tin. Waited a long time for this,was not disappointed. P.s great communication from FLO for the whole purchase 👍

Ordered well in advance of Christmas, but with the expected delay in shipping didn't expect to recieve this before Febuary. I was delighted to recieve it before Christmas! Excellent service from FLO. Now, could you arrange for the clouds to disappear too?

Too early to review the instrument itself but thanks to FLO for being able to ship the instrument just pre Christmas - excellent continued service with frequent status updates despite the obvious challenges - a great surprise to receive ahead of the break. Thanks as always, Andrew.
SkyWatcher 254 Dobsonian telescope
Monday, 11 May 2020 | Paul
I decoded to upgrade to a larger telescope having purchased a 150 mm Sky Watcher Dobsonian. I checked out the internet and had several choices. The FLO price was the best for a suitable 10 ich telescope over other makes offering the same type . The setting up was very straight forward Everything fitted together very well. The instructions with the telescope are well written with good illustrations and technical detail. You will find the 10 inch is heavy and not that easy to move around. I have to do this in two parts taking the mount out and then the scope tube and fitting together which is very straight forward. I am looking into using a small trolley to move in and out of my shed onto my decking.
I have purchase a laser Collimator which is fantastic and definitely worth the buying as it only takes a few minutes to re collimate. I have also invested in a Barlow lens and some filters. You do have to learn how to use a Dobsonian moving the telescope to keep the image in the eyepiece, with practice you get good at it. I have only had the chance to view Venus and a rather full Moon since my purchase. Venus is a good size and much better using a blue filter. Moon detail is so clear and up close using the Barlow. Cant wait till the moon gets away from full and the sky is darker so I can few deep space objects like galaxies, which is the main reason for my upgrade from the 6 inch. Great service from FLO the scope arrived next day by FedEx with full tracking emailed.very please with my new telescope.
An absolutely amazing telescope!

Compared to my old telescope, this telescope is literally a beast! Wherever I point it I'm able to see stars, some of the brighter stars have clear colour differences! Tonight was my first night using it, I was able to find a few star clusters and even Andromeda, the views were incredible.
The weight of the telescope is completely fine for me, despite the telescopes size. I highly recommend transporting the mount and the telescope separately, it's very easy to do and makes the weight bearable.
Assembling and collimating the telescope was very simple and easy to do, just follow the instructions and nothing will go wrong. I recommend doing the collimation with a laser collimator, it saves a lot of time.
I haven't noticed any chromatic aberration or coma when using the scope, which means the views are very clear and detailed! If you're into visual astronomy and basic astrophotography (e.g. taking photographs of the Moon and Jupiter, I wouldn't recommend trying to capture DSO's as it isn't motorised, this telescope is a must!
The best scope money can buy

This scope is excellent if you want to observe both the planets and DSO's (deep sky objects). I have had this scope for almost a year, and I have had many good times with it, even tho I hav only had the opportunity to observe from my light polluted flat.
I will divide this review into two sections:
Observing deep sky objects. and observing the planets and our moon.
This is a very large scope so if you are considering to buy this for you kid, I would only do so if you can be there to carry it outside for him/her. When I say kid I mean about ten years and below. I am 15, and every time I am going to observe, I carry the telescope out in two parts, the base and then the tube itself. This works very well, and if you are going to travel with it, then I would do the same when you put it in the car.
I have been using this scope with my explore scientific 82 degree eyepieces.
Observing the deep sky objects:
This is a very capable scope since its primary mirror is 250mm/10 inches. This makes it one of the best, if not the best telescope for the money when observing deep sky objects. I have seen galaxies, star clusters and both planetary- and emission nebula through this scope, and you have to remember that this is from a light polluted city.
Observing the planets and our moon:
People often consider the dobs in the 6"-10" size as a good all-around scope and I couldn't agree more. With this scope I have seen the moon in great detail and with the explore scientific 4.7mm eyepiece I have resolved craters with a diameter down to 3km.
The planets I have observed are Jupiter, Uranus and Neptune.
Observing Jupiter with the 8.8mm eyepiece the cloud bands are as clear as day, and the moons of Jupiter can be seen as bright stars. The most beautiful thing I have seen was probably when there was a double moon transit on Jupiter. The banding was clear and two black dots on the planets disk was easily resolved. You could also tell a difference in the size of the two shadows. When observing Uranus only a very small disk and a faint trace of color can be seen, and on Neptune, you can just be able to tell it's a disk rather than a dot. This is still very good, and no telescope in this price-range is going to outmatch this.
All in all, I would really recommend this telescope if you want something that is capable of showing you the planets and many deep sky objects.

I bought this last week and got to use it properly for the first time on Monday and then again yesterday. It is really easy to use being on the dobsonian mount and is not to big to lug around. The tube fits perfectly across the back of my peugeot 306 with the base easily going in the boot. Assembly is very quick and takes almost no time. So far I have been able to find the Leo Triple galaxies, Andromeda galaxy, Beehive Cluster and a few other deep sky objects. The lenses that are included are ok but not brilliant. The 25mm is better than the 10mm. The service from FLO (Martin specifically) was also fantastic. I ordered the scope on Tuesday at about 2pm and it was with me the next day (just a shame the clouds seemed to come with it too! lol)

I have had the sky-watcher 250xp dobson now for about three weeks, only had chance to use it a couple of times.
first impression when I received this scope were; very well made, easy to assemble. on using the scope; collects alot of light and very clear views although the lenses that come with this scope are not that good, so I would set aside a few pounds for some decent ep's..I have looked at Jupiter and the light gathered from it is excellent!! I have ordered a decent barlow lens and a good 10" ep so the scope can show what it can really do!!
I was undicided on this scope and the sky-watcher

I have now owned this telescope for two years in a semi rural location. It does exactly what you would expect for a large dob scope. It collects so much light which has allowed me to see over 400 galaxies!
Its limiting magnitude in practice is around 14.2!
It is also a fantastic scope for planets, double stars, star clusters.
The low F ratio does mean that you have to choose your eyepieces carefully to avoid the seagulls effect at the edge of the field.
It is just at the limit of portability when the tube and mount are carried sepately.
Would I buy this scope again. You bet!
