And another beauty here too!

Here's mine. Mirror cell was modded.

I'm going to change some other things in the coming months but nothing big.

You should use nylon pads for the mirror not felt 👍

That is certainly what I would regard as a "full-thickness mirror"!

Mm.. interesting. I tried both actually, and didn't see any difference.

NICE !!!  More pictures please. Great choice of focuser and finder too. How is the thicker mirror for cooling, do you have active cooling with fan/fans?

[Victor Boesen]

I'll join the thread;))

I've had my dob for almost 3 years now and it has (and is still) served me very well. I've brought it to plenty of public events and I've found that it's often the best scope there.

Great to see so many dobs out there!

They are nice scopes give a nice image 

Thank you Gary,

In my opinion it is the best value beginner scope around. It has shown me some stunning views and opened my eyes up and really got me into astronomy. I don't think I will ever sell the little 200p

I can see you have experience with some very nice larger dobs from 12 to 18" In you opinion what has been the sweet spot in performance and portability? I would like something in the 14" region next.

Regards

Barry

I’d say 14 ” inch is the sweet spot as just light enough to be portable but big enough to show good results the Sumerian Ultra I had was 14 but the scope was to flimsy to hold collimation where as the David Lukehurst is nice and sturdy but still portable 

[Barry-W-Fenner]

Cheers all! Hope the sky's are clear for you and happy viewing!

Did the glass of wine come with that.I must get a glass for mine.

That's a great work!

Right I need me an 8 or 10” Dob lol

[michael.h.f.wilkinson]

A little 4.5" I built for the kids (they are much bigger now). Only drawback: no centre spot on the main mirror making it a bit tricky to collimate. I am getting a centre spot shortly, and will then probably donate it to the university's astronomy outreach group

[JOC]

This is my 8" Goto truss-tube SW 200P (the first of these of this size on this thread I think) doing outreach work as a solar viewer, except we didn't get the sun out that day apart from literally the 30s I took this photo!!  so no filter present and it is actually looking at a distant aerial 

It has a modified focus wheel to help with fine focus (I can't justify the expense of a Lacerta)

 

and is normally used with my favourite Y set up of finders 

and here is her solar filter

Outside cooling on a beautiful Sunday afternoon 🙂

Is it the scope cooling ready for later😉 

Or is it the beer at the base of the scope 😀

My 12 is out as well. It has been a nice sunny day so I'm hoping for a nice clear night to match

[Barry-W-Fenner]

John that OO 12" dob is pukka!  I bet the views are ace. I would really like an Orion model next around that size. When I have fully explored the 200p I will consider looking for one and a more premium brand of eye pieces to suit.

That said the 12" OO on  ABS with steel track focuser for £600 has had me sweating recently 😁

How do you think the sky will behave tonight. It looks amazing out but in my limited experience I don't know if that is a good thing?

Thanks Baz.

I reckon the transparency will be quite good but the seeing not so steady. It's a bit blustery here so I'm going to be sticking to low to medium magnifications anyway.

A better DSO night than a high power observing one perhaps ?

Now I've said that it will probably turn out to be quite the opposite

 Nothing fancy here...

Hoping for a decent night
