swamp thing

What's that sliding thing on the underside of the Ota?

That is a Magnetic knife rack with an olympic weight collar on it. 

Well done Dom I wasn't quite brave enough to post mine amongst such big brothers!

Come on and post. All dob's are cool matey.

Here's my baby Dob

Sadly  I do now as normal viewing is likely to be a thing of the past for me soon.

Oh I'm sorry.

For imaging purposes you'll be wanting either a newt, or an old sewer pipe with glass stuck in the end  a refractor mounted on an EQ. The key I'm afraid is the EQ mount. This bane of visual observing is unfortunately needed to allow for the long exposures required for astro imaging.

^^^^^ Now thats a newt.

Never had a Dob  what are the drawbacks?  And how good are they for imaging?

 There are no drawbacks to a dob. Who cares about imaging?  

lets get the dobs back on top were they belong

On top of where mate?

Hope to get the next build thread on later

Damian

Looking forward to that Damian

Great to see so many home and amateur built scopes on this thread. The others all have their owners home grown personal touches too. Dobs are just great huh

Not forgetting quaoar's mighty webster. Thanks for the pic mate.

 Gorgeous scope, shame I didn't manage a peek at SGLX :-(

Yeah sorry about that mate. I really need to sort the anti dew kit. One of the other dob mob (Mike) is going to help me sort that. Electrickery isn't really my thing.

My home made  20" Dob

give it him both barrels stu

You can wrap up en all, Frankenscope   

Oi!!! I was just about to post some ya git

Need some close ups of yours too Steve, lovely dovetails

Come to Dobfest then

Come on quaoar where's that huge 28" Webster. We're all waiting to see it again

Heres my 20" f 4.7 surrier truss dob

Knowing how short ( ) you are Mathew. That looks small..........not. What a beast that is

I compared Olly's 13mm Ethos to my 12T4 Nagler (under mediocre seeing conditions), and did not find the ethos a clear winner. Y

Lost track of how many times I've made this comparison myself Michael. I still have my 12T4

The 13mm Ethos is not on my wish list. A case of nice but no thanks I don't feel the need for the field at this focal length. The nagler is wide and certainly sharp enough for me. 

Bit of a collection going on there Shane

I do like my Naglers too. 

So there may be a role that wider angle eyepieces could play in helping you make the best of your observing circumstances.

Indeed

Its important to note that seeing the edge of low surface brightness objects can mean the difference between seeing them and missing them altogether.

Wide fields can really help here specially when increasing power to gain contrast.

With narrow fields its very easy to "Look through" objects rather than at them. Wide fields may help you pick out the edges better and increase your chances of success.

Note to the Powers that be ...

If it hasn't already happened , this thread needs pinning somewhere prominent so it can be easily found and revisited ... 

Already done Steve, This is a sticky in the observing deep sky section.

What a great post

Nice to see you back on the forum Rob.

I have them stored by focal length increasing from front to back. I can reach in and pick out what I need without looking.

Aah right. Makes sense. Thanks

Laservet how do you know which eyepiece is which with them stored that way round?

Nice one Steve.

I am seriously thinking about modding my scope that way - making sure the 'dolly' is detachable when required.

It's a relatively simple idea the axle fits into two rebates cut into the ply braces on each wheelbarrow handle. The axle fits from underneath. One simply rocks the Dob backwards and fits the axle into the slots. Gravity does the rest.

The handles are held on by star headed clamp bolts threaded into t nuts on the rocker box. The axle itself is an ash hod handle.

Here's my seventy+ year old dad wheeling my 20" Dob about in his back yard.

Wheelbarrow handles make moving large scopes very easy indeed.

I went with a single wheel, as I needed mine to be more manoeuvrable.

Hi

I would ask first, what are you hoping to use this for, you kinda have most basses covered with your 100deg 20mm eyepiece?

Mmmm! Tempting. Can't justify it right now though.
