im assuming you mean only dobs we "have" owned and not current dobs correct?.

Title changed to “Show Us Ypur Dobs”.

Yes, particularly when I forget some that I've owned !

I should probably put this thread in the scopes discussion area - I can leave a link here to it as well though. Is that OK ?

Yes please move it. 👍🏻

Speaking of breaking the rules does an Synscan Skytee II mount count? 🤔

One of my old projects.

Do ypu find it a bit scary when you realise how many scopes you’ve owned???  🙀🙀🙀

Well, there is a "gap in the market" there

Sorted 😁

Inspired by the recent thread on showing your Alt-Az mounts decided to start this thread. 

So as the title says lets see what your “Dob History” is including what you have now. 🙂

I’ve had 8”, 10” and 12” Skywatcher dobs. The 10” was a Flex Tube GOTO that I converted into a solid tube by getting hold of a newt solid tube. 

Then there was a 16” Meade Lightbridge. Big and heavy and not the greatest mirror. 

Replaced the Lightbridge with an OD350 with 1/10pv mirror. Much modified with a StellarCat drive and Argo Navis and mounted on a Scopebuggy.

Now have  Bresser Messier 10” dob. Lovely scope and not too big. 👍🏻

Telescope Express makes adapters to order but not exactly cheap. ££££. Commercial machine shops do charge an arm and a leg.

If you can find a model engineer that might be a lot cheaper. 

Wondering if I should start a “ Dobs I have Owned “ thread?  🤔

I looked at the Panther but something about it put me off. Glad I waited for the AZ100.

Tripple scopes?

Why not. 😁

Oh yes allmost forgot this little mount as well. 😁

I have have had a few Alt Az mounts I suppose. 🤔

• Manfrotto 410 geared head with a Megrez 72
• Manfrotto 405 geared head with a Lyra 102 f11
• Skytee II with a Lyra 102 f/11 PST mod and another Lyra for white light.
• TS-AZ5 (Skytee)
• Skywatcher AZ5
• Skywatcher AZ-EQ5
• No pics bit also a WO EZtouch and a Giro mini
• Skywatcher SolarQuest 
• CPC 1100

Looks like I’ll have to sort out a few photos. 😁

The ES is  very nearly as good as the Powermate in most scopes. Maybe in a very fast scope the ES might be only 95% as good. 

Had the ES 2” 2x but it was a big heavy lump though.. Opticstar does the same tele extender at a bit better price.

Some things they won’t ship to the UK but if they do it clearly shows that it can be shipped to the UK.

Have bought a number of little items from Amazon.com when I couldn’t find them here or they were cheaper.

If ordered from Amazon.com the goods get delivered by Amazon in the UK just like any regular Amazon delivery. Just takes a few days longer and no customs to bother with as it’s all handled by Amazon. Painless. 👍🏻

Here you go. Amazon is cheaper than eBay as shipping is so much cheaper.

Crazy price if ordered from Amazon UK

https://www.amazon.co.uk/Telescope-Eyepieces-Barlow-Other-Accessories/dp/B013SD5T24/ref=sr_1_6?keywords=eyepiece+caps&qid=1580213493&sr=8-6

A set of the end caps on eBay only £6.12 but £11.10 postage. Bit lower price if ordered from Amazon.com with shipping to UK.

And for the other end the tops from plastic milk bottles fit many 1.25” eyepieces.

Goes back tp the Big Bang.and the way the universe formed.

Best thing for setting up a secondary properly is to get a Concentre. No other method comes close in accuracy and it is so easy to use. It’s a simple device but I wouldn’t be without one.

There are elliptical galaxies that aren’t flat but this will illustrate the different types.
