The new Sky-Watcher Explorer-200P DS has the same superb parabolic primary mirror as the Explorer-200P but features a 1.25"/2" Dual-Speed 10:1 ratio focuser for enhanced focus control and a shorter tube length with the secondary mirror positioned closer to the primary mirror for more convenient prime-focus photography. 

The Sky-Watcher Coma Corrector is also available for astro-photography. 

You need only a T-Ring to fit your DSLR to the focusers T-thread but for best results you will need to use a Coma Corrector. (When using a Coma Corrector you will need an M48 Ring to suit your camera).

Best bang for your buck
Thursday, 24 December 2020  | 

I wanted to upgrade from a 130mm (650 mm focal lenght) newtonian, to something that I could still use to capture some nebula and would also really get some more detail on targets like M33 Triangulum; I haven't been disappointed! One note to to people is really to consider the camera sensor you are planning to use too; as it makes a huge difference of your field of view! I did collimate this on arrival and it was slightly out - nothing major though and not surprising given it has been shipped from the UK to Europe.

The surprise for me was really that the increased aperture was not the main thing I liked, the general build was so much more sturdy that my previous scope. The focuser is real a game changer, and also the rings, dovetail and guide scope being included were all very nice touches. I am using this with the NEQ6 pro and I dont have any issues with the weight. I do see these sold with the HEQ5 Pro and wonder if this OTA with all the other imaging accessories may start to push the limits of the mount a little (just something to do a little research on if you are looking to purchase).

Anyway, I literally have no regrets with this OTA, it is fantastic, and allows me to get good signal in a much shorter time which is important as I have a fairly limited sky view.

Service was spot on from flow - there was a fairly long lead time for this but all well communicated and clear - arrived exactly when they said it would.

Cool scope with bags of potential
Monday, 11 May 2020  | 

I had been observing using a Skywatcher 120mm Refractor. It's a great scope. I found myself becoming more interested in imaging than viewing. I got some okay results from the 120 (CA was obviously a thing, as was the tight FOV).

I took a break and decided to use lockdown as a good reason to restart the hobby. I'd been considering the 200P-DS for a while. (several years!) It offered me a nice fast scope at an affordable price. (I had considered a an APO refractor, but the cost of those soon mounts up). It was also very much weighted toward astrophotography.

In terms of imaging it's very much tailored to my level of skill - I've learned the basics and been fighting with a refractor. I found that it's much more forgiving than my refractor and it's not too fast to present another learning curve. So I reckon it's a good intermediate to advanced level telescope. I'll probably hit my limit for I exceed the scopes!

So far the scope has exceeded my expectations. Although designed more for imaging I have had some pretty good visual experiences so far. It's early days and a 90% moon has been making life interesting. Imaging - so far M101 and M13 have been targets and I've been very impressed with the results - focusing is especially good with the dual speed controls. So far coma has not been much of an issue, but my sessions have been limited by light and time.

Fit finish and build quality is great. Collimation was more or less spot on out of the box. Bundled accessories are all well made and machined.

The scope is heavy and a little bulky - but still very manageable. It really is in the sweet spot where size and aperture are just right.

Great scope - I love it!

Firstly, thank you to FLO for their amazing service. Order received at 9am Monday. Telescope arrived 11:40am Tuesday. The 200 PDS is an excellent instrument and exceeds my previous Skywatcher 200p that I bought in 2002. The new model is an absolute breeze to collomate, taking only 2-3 minutes to do both the primary and secondary mirrors (previous model had tiny, equal size possidrive screws for the primary. Nightmare) and the image quality is first class. Easily observed the Ring Nebula in Lyra, even under a bright 11 day moon. Resolution of the "double-double" in Lyra was easily achieved. Detail on the surface of Jupiter, even though only 14 degrees above the horizon, so not really favourable conditions was quite amazing. Great Red Spot easily observed. Jupiter will look stunning in 5 years when it is well placed for observers in Northern latitudes. I can't recommend this telescope enough.

my great new sky machine

i really have been due to call you all just to thank you all for the FANTASTIC SERVICE YOU GAVE ME LAST WEEK..
I could not believe the speed with which you processed the order(less than a day i think) The price is amazing--and the quality of these scopes is legendary..The optics were a little out of collimation-probably due to transport--and with this -it easily split the 4 components of EPSILON LYRAE with separations of about 1.6 seconds of arc..
When set--the optics will be top notch..
This is an amazing company you are driving..very good luck with all you do in the future--keep up the good work--AND if anyone i know is in need of top gear---i shall definitely put you all up on the stand..
Well done--20* for the whole thing..
kindest regards--Garreth
