About this product

Model:  eq6-extension-tube-20857
Part Number:  20857

The extension tube extends the height of an NEQ6 / EQ6-R / AZ-EQ6-GT mount by 8".

Especially useful for owners of long-tube refractor telescopes because it positions the eyepiece at a more comfortable height and prevents the telescope from hitting a tripod leg.

A metal tube

A sturdy reassuringly heavy metal tube that does the job.
It does make the setup more top heavy (as expected) so take that in to account when setting up.

Sky-Watcher EQ6 Extension Tube for NEQ6 / EQ6-R / AZ-EQ6
14 March 2022  | 

Fits my EQ6-R Pro perfectly!!!!!! I was a little concerned after reading reviews on it. Once installed it did have some wiggle but realized I had not tightened it down all the way. After I tightened it it was PERFECT. SHIPPING WAS EXTREMELY FAST AROVED 6 days ahead of schedule.

Perfect match
12 February 2022  | 

Solid built, great match, but you will think twice to bring your complete rig outside unless you are 100% sure the sky is clear for at least 50% of the night. Seriously, its difficult to carry your completely setup rig with this thing.

Excellent product

I purchased this because my Skywatcher 200P was colliding with the tripod legs of the Eq6Rpro when imaging objects high in the sky. The extension tube is well made and very sturdy. After fitting it was very stable and I imaged the Flaming Star Nebula with no problems. I also appreciated the ease of looking through the finderscope with the greater height. The only downside is that the Eq6Rpro centre of gravity is now much higher, making it more difficult to carry.

Rock Solid

The extension tube is straightforward to assemble and once all the bolts are fully tightened it is very solid indeed.

Does what it supposed to
08 June 2021  | 

I recently bought an AZ-EQ6, it's a great mount. I use a 905mm focal length refractor and with the flattener and camera it is bound to foul on the legs. of the tripod. The pier extension fixes this by raising everything up by just enough to allow for stress free unattended imaging.

Now here's a point to note. Skywatcher appear to have made a design change. The black plastic section that mates with the tripod is now fitted with a lip and a rubberised base. meaning it inserts the other way around. This appears to be to address rotation issues. The disconcerting element of the change is the insert that previously fitted inside the hole in the tripod is now on the other side. This means you only have 4-5 turns of the securing bolt (as opposed to many). However the mount is secure and operates fine under load. Obviously there is less screw securing the the pier than there would be the mount.

The grippier base and elimination of metal to metal contact does seem to be secure and I have not had issues with rotation of the extension. The bolt holes are machined and positioned correct and I am not experiencing an wobble.

Overall this is a simple solution to anyone using a longer scope or simply needing some extra elevation. At heart it's a steel tube with some holes machined in it. So while it lacks the excitement of a RASA or a CMOS camera.... It does what it's supposed to!

Shorter than I was expecting!
03 June 2021  | 

Not really but is shorter than the eq5sí pillar. Once everything really tightened is stable enough, the pad on the bottom surface grips well so not noticed any slippage in use. One small negative, one of the holes was slightly off so took some jiggling and one bolt had to go in at a slight angle to grip the head piece, but did grip in the end, bolt heads do seem a little bit on the small side but explains why the 6 holes are on the larger size!! Great service from FLO -many thanks

Works well

Works well and to its purpose. Of course more length to the pier reduces stability, but that is what to expect.

Skywatcher Tripod Pier Extension Tube
04 August 2020  | 

Like others I did experience slight twisting of the pier at the lower tripod head end once the mount was placed on the top but found with the weight of the mount I was also able to crank the lower securing bolt, using a piece of rag for extra grip, a little further which totally eliminated this issue. Some of the bolt holes as reported before were out but didn't affect boltinf the end pieces on. Nice white powder coating, item is quite heavy and robust which is great. I bought some Neoprene gasket material to make some joint seals but don't think I will need it after all. Good price, delivery was quick but with the price of the delivery I would fully expect that anyway! A good addition, great for raising the mount for me as I use it with an FS128 Tak Apo refractor which can be quite awkward when observing near or at the zenith.

Sorting the Extension Tube Rotation Issue...
23 November 2019  | 

I sorted the extension tube rotation issue by buying 2 x 200mm square sheets of neoprene rubber from Amazon one 2mm thick the other 3mm thick. From the 3mm thick sheet I cut two washers with on OD of 64mm and an ID of 32mm these are then placed or glued into the recess on the tripod top plate. From the 2mm thick sheet I cut one washer with an OD of 94mm and an ID of 32mm this can be placed under or glued to the black plate at the bottom of the extension tube. Before use roughen all the washers on both sides with sand paper. Cutting the washers from the neoprene sheet is easiest using a pair of engineers dividers initially (sharpen the points before use if necessary) and a craft knife. After this no more accidental rotation; an easy fix that took no more than one hour and that Skywatcher could/should have included especially in conjunction with the EQ6-R.

Q1. Can I use the Skywatcher EQ6 Extension Tube with an AZ EQ6 GT?

Yes, the Az EQ6 has the same mount fitting as the EQ6, the extension will fit nicely.
