Optical Tube Assembly
The new Sky-Watcher Explorer-130P DS has the same superb parabolic primary mirror as the Explorer-130P 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 Explorer 130P-DS is a surprisingly capable imaging Newtonian; check out the images and discussion from owners at Stargazerslounge.
The Sky-Watcher Coma Corrector is also available for astrophotography.
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).

I have been using this scope mainly for imaging during the past 3 or 4 weeks. I must say first that when it arrived it was seriously not collimated. Fortunately I bought the Stella Lira cheshire and that helped me collimate the scope in a reasonable amount of time. So I made some deep sky pictures with some succes (without the use of a coma corrector) with a small camera sensor (IMX585), and also performed some solar imaging as well. No complains about this, to be honest. I decided then to purchase the ZWO EAF in order to "formally" include this scope for my imaging sessions (especially for citizen science, taking spectra of variable stars). To my surprise I could not remove the focuser knob from the shaft, because it seems that it was glued to it (it did not come with a grip screw). To be honest, I did not want to use pressure clamps to try to loosen the knob, because I did not want to cause any damage to the shaft and to the knob. So, I am not able to take this knob out and thus install my recently received EAF. Tried to find a supplier for the shaft (4 mm diameter x 80 mm long), but I could not find a single one (not even in hobby on-line stores). This is very unfortunate. I had a Sky-Watcher Mak-Cas scope, and it turned out to be very good (but too slow for my purposes). I was aware that for the price I was not going to obtain a top notch scope, but this lack of any quality control from Sky-Watcher is somehow worrying. The scope is good but for seasoned amateur astronomers, not for beginners. If you are looking for a good newtonian, and you are a beginner, please check out other options, although they might cost a little bit more (but will guarantee your enjoyment).
It's not calle the 'apo killer' for nothing

Had the scope for just over 6 months. I bought it in case I decided to do imaging. That being said I've almost exclusively used it for visual.
It is fantastic for visual. Bright views of DSO and very sharp views of the planets when collimated.
I've done a few images with it, using an IMAX 533 sensor and with a smaller sensor it produces fairly minimal coma.
Good begginer scope for astrophotgraphy and visual

I bought this to compliment an 8" Stella Lyra Dobsonian. I do some visual from the garden but due to a combination of light pollution and trees I am limited in my view. so also have a travel rig. or to set a rig taking pics whilst using the dob.
I have a Skywater 200PDS/EQ5 that I had bought second hand, its light gathering was great (and was the reason I bought the dob). I had bought this rig just it for the mount and acessories (guide scope./coma correcter) I had planned to sell the tube and get something smaller for use on the EQ5 at home as well as on an AZT GTI when travelling to sites on foot
The 130PDS is pretty much the same as the 200PDS just smaller. and a lot lighter! It has a good dual speed focuser that doesn't slip even with a camera attached. The included eye piece is a 28mm plossl and is of good quality (normally bundled in eye pieces aren't great). The finder scope is good,so I felt no need to add a telrad and with the 1.25" adaptor and the extension tube I have been able to use my exsiting eye pieces and DSLR.
I unpacked the tube, set it up in 5 mins and had it mounted on the AZ GTI ready for use. I was lucky to get a clear night the day it arrived, the moon and Jupiter looked great through it. I had no issues using it on an AZ GTI the mount was nice and stable. I have yet to test it on the EQ5 but will do.
Have a look on cloudynights.com and there are a lot of threads on astrohotography with this OTA . Glen (Astro Bloke on youtube) also uses the 130PDS for a lot of his astrophotography. Its a really good scope for the money.
Amazing for the price, exceptionally well packaged, delivered very quickly.

The telescope arrived packaged well enough to survive being used as a football by delivery companies. FLO forgot to include the clouds in the box, so I was able to set it up on the very night it arrived, and after spending a bit of time working out how the camera adapter fits together with the coma corrector (bought separately) I was able to snap a few globular clusters. The focal length is 650mm, only 50mm longer than the camera zoom lens I was using before, but the result was much sharper and brighter. I haven't gone through the full collimation process yet, so it might even get a little better still. Very pleased.
Good optics , FLO great service

First I want to start by congratulating FLO for their great service, this applies to the ease of purchasing on the online store page which was very easy and accurate because it said that the product was available and it was, delivery by DHL from the united kingdom it was fast and the merchandise arrived 3 days before the date stipulated by DHL, the telescope arrived well packaged with good protection on the outside of the box, which makes me feel good because they made an effort to make a good package for such a long trip to United States, the telescope arrived in excellent condition, it was out of collimation which is normal due to the long trip, but that was fixed immediately, I am very happy with the quality of the optics and the double speed focuser which it allows me to make optical fine tuning adjustments, it was a good purchase with the number of adapters and it also included the finder scope and the tube rings and the dove tail, for the price I think I made a good purchase, but the FLO service was very satisfactory. thanks FlO

Have had this tube a few weeks now and managed to make a start with my observing. On the whole it seems a strong well made telescope. The images with the supplied eyepiece seem very clear. It is a elevation to see the moon using this telescope, and myriad of stars that appear out of the night sky is quite astonishing.
The service from FLO was very good. There was a small damaged component but this was dealt with promptly.
I purchased a Cheshire Collimator and this works well.

I've started my astrophotography journey with this and I am enjoying every minute of it. It is a highly capable scope.
28 July 2020 | David
A superb scope I have been using this for a couple of weeks as the weather did clear up on some days.
I have connected this up with the star discovery WiFi mount and it works wonders. I have seen many objects clusters and galaxies such as the andromeda and many that are faint.
Also itís good for planetary good details with Saturn and Jupiter when a Barlow and digital zoom on the camera are used thanks FLO.

Great product.. At a fantastic price..
Very well made.. Very good quality..just needed a few minor tweeks to set up.. Puts it from 4* to 5*....A bargin.. 👍

This was my second ever telescope, for my first astrophotography rig. So far it has performed exceptionally. I use it with a canon 600D on a HEQ5 mount. There was no need for collimation out of the box and the stock focuser I've personally found to be excellent.

Q1. Are tube rings and a dovetail included?
Yes, the OTA comes with suitable tube rings and Vixen-style dovetail bar.
Q2. What is the weight please?
The weight is approx 4 kg.
Q3. How important is a coma corrector for imaging?
A coma corrector 'flattens out' the optics which greatly improves the star shapes away from the centre of your images.
If you are using say a planetary camera with a small sensor you don't need a coma corrector. However, if you are using a large sensor camera such as a DLSR then a coma corrector does provide a big improvement in image quality.
We recommend the following coma correctors for f/5 Newtonians:
Q4. Does it come with a 2" to 1.25" adapter?
Yes, the 2" focuser comes with a 2" to 1.25" adapter included for use with 1.25" accessories.
