The Sky-Watcher extension tube extends the height of EQ5/HEQ5/AZ-EQ5 mounts by about 16" so is a popular choice with owners of long-tube refractor telescopes as it places the eyepiece at a more comfortable height and prevents the telescope hitting a tripod leg.
The extension tube is installed between the top of the tripod and the mount head. Mount stability is maintained through the metal, heavy-duty construction of the tube.
This is for an AZ-EQ6 but the principle is the same.

I placed my order for the Sky-Watcher extension tube on April 26, 2022 and I received it in Canada on May 1, 2022, just 5 days! That is better than we do domestically with our post office!
The pier extension went together without issue. I did make a small insert to put on the HEQ5 pin to prevent the pier from moving, as I want to use it for imaging. It is now rock solid and does not move at all. Very pleased with the great customer service, fast shipping and the product. Highly recommended.

I bought the HEQ5 tripod extension because I live near the equator and my counterweights hit the tripod legs. I was initially going to buy the pier, but the extension tube was.....cheaper. I had read that the extension tube doesn't fit tightly over the peg. The user reviews were correct, it does not fit well.
My solution was to drill a small hole through both the extension tube and the peg and tap a screw. now the extension tube is very stable and doesn't budge.
I hope my solution will help others in a similar situation.
Great service as usual from FLO. Terrible product though.

FLO are great as usual. This arrived next day. They are always my goto supplier.
Onto the extension though.
Its big and heavy. Which is good. But the baseplate is terrible. The hole for the north peg is abount 5 times the size it needs to be. The entire tube rotates with the HEQ5 on top of it. No matter how hard you do the centre nut up.
This ruins your PA. Dont buy it. Especially if you are imaging. Over all not what I expected from SkyWatcher. Not their usual precise workmanship. Massive letdown.
Skywatcher Extension tube for my Sabre mount
Monday, 1 February 2021 | Michael
I purchased this extension for use with my Sabre V2 mount and it works a treat.
4 stars - one of the threads on the tube was stripped and needed re threading - QC ?
On the whole first class from FLO Again.
Skywatcher Extension tube for HEQ 5 mount.
Monday, 18 January 2021 | Dave
As always, first class service from FLO.
Slightly less impressed with the ext tube though.
The hole in the base plate is way too big for the peg on the heq5 tripod top. Even with things tightened up it's fairly easy to move the tube, particularly in the "unscrewing" direction. It needs some packing pieces in, 5mm thick each side of the peg to stop the movement.
The bolts supplied to fit the base and top plate don't come with washers of any sort. I think some spring washers would be good.
Sky-Watcher Extension Tube for EQ5 / HEQ5 / AZ-EQ5
Friday, 16 October 2020 | John
I bought this pier extension because I managed to damage my camera screen when it collided with the tripod whilst imaging at the zenith (Skywatcher 100ED DS Pro) HEQ5 mount.)
Very satisfied with the usual excellent service, but not so with the product.
The first time I used the item all went well and I was very pleased, however, the second and third times were a total failure!
I had serious problems getting my alignment stars to line up and couldn't understand the issue.
The third time was the last straw and so I removed the pier extension...I then didn't have a problem with alignment stars and my imaging session went well.
I'm a motor engineer with 49 years experience, now retired, so I decided to trouble shoot the issue.
I found the problem very quickly...
The part that fits to the tripod does not fit properly, in that it feels tight and secure but if you hold the telescope and try to move the mount the whole pier extension moves quite easily..I don't need to explain what that does to your polar alignment and consequently, star alignment.
The problem is that the base plate has a hole machined in it to allow the plate to fit over the polar adjustment peg on the tripod, but it is far too big allowing the whole of the bottom section of the pier tube to move about even though the main screw and the 3 mounting screws are rock solid tight!
I haven't yet solved the problem, but I intend to make an adapter to fit over the tripod peg and to drill and tap the lower mounting plate and fit screws in to stop the plate from moving.
I really like the pier extension, but it is far from a finished product!
Using it with a Explore Scientific Twilight I
Wednesday, 14 October 2020 | Uzzi
First time buyer here at FLO and I couldn’t be happier. Everything went fine and in my opinion way faster than any other telescope store I’ve bought from. For example, I placed my order, was sent next day and arrived here in Mexico just 3 days after been ordered (through DHL).
Now back to the extension. I bought it for my Explore Scientific Twilight I because I’m 1.9m (6´2”) and since I installed it I noticed that the 6kg of this tube really help anchoring the mount a lot! Also, I don’t break my neck trying to point out the finder and overall the comfort levels just went up.
Now, a note of warning for those looking to match this extension with an ES Twilight I, it does not fit exactly that AltAz head, you’ll have to “shave off” a few mm from the nipples (?) that come with it to achieve a perfect fit.
The only disappointment I had was that the extension arrived with an ugly rust stain that can’t be cleaned up with a cloth, it seems to me that I’ll have to buff it off with some light sand paper.

Works well, simple to fix to the tripod and mount. A little heavy and a little expensive for what is a piece of pipe with two end attachments plus some powder coating.

This also fits the Skywatcher EQM-35 Pro.
Very solid, I'm looking forward to it getting dark enough here in Norway

Simple but an excellent product.
Allows more usable height for your tripod or more stability for your mount by being able to set the tripod at lowest setting whilst maintaining desired height for your scope.
The top of the tube also has a thinner Azimuth pin/peg which fits the 3/8 inch photo adapter sold by FLO with no filing of the adapter necessary.
Fast and efficient ordering and delivery from FLO- as ever.
