Guest fish Posted June 24, 2012 Share Posted June 24, 2012 Finnished the main parts of my Dob base, fitting a Lazy susan bearing, moded center pin and adjustable setting circle. Things left to do are fit battery and box, wixey,led lighting on setting circle and Telrad finder. The setting circle was a modded one from the net ,it's in four A4 Jpegs, just print all four ,cut out, then laminate in one A4 folder . Cut them out and stick together. The setting circle is fixed to a rubber mat that is held in place with the four spacers and can move to allow adjustment. A big thank you to Daz for all of the info you have published on the net, it is a great help. Link to comment Share on other sites More sharing options...
Daz Type-R Posted June 25, 2012 Share Posted June 25, 2012 Looking good Keith, that setting circle mod looks good too, are you planing on cutting a hole out of the "top" board so you can see the setting circle? Still need to get mine enlarged, printed and then laminated, must get round to it sooner or later. Link to comment Share on other sites More sharing options...
Rusty Strings Posted June 25, 2012 Share Posted June 25, 2012 Nicely done, you won't regret any of them Link to comment Share on other sites More sharing options...
Guest fish Posted June 25, 2012 Share Posted June 25, 2012 Thanks for the comments I will add pics to the thread as I complete bits just for anyone thats interested . The hole is cut, just trying to work out a way of finnishing the hole so it looks good, I have found an old Cokin 3d close up filter that enlarges the numbers for my old eyes but need to work out a way of making it look ok rather than an old filter stuck on the top.

Guest fish Posted June 30, 2012 Share Posted June 30, 2012 Finnished adding bits to the top of the Dob :- Orion centering adapter, Telrad and Wixey. Very happy with the additions but the tube is now top heavy . Made a holder for my old filter , needs to be screwed down and inside the hole blacked. Next on the list will be battery box and LED light on the setting circle. Link to comment Share on other sites More sharing options...

Guest drchrisjackson Posted July 8, 2012 Share Posted July 8, 2012 Have you guys read: "Astronomy Hacks" ... Check it out on Amazon, I have an xx14i and that book gave me invaluable advice regarding dob mods. My second biggest influence has been "jays astronomical observing blog" which again details numerous projects and advice. Cheers cj Link to comment Share on other sites More sharing options...
Tweedledee Posted July 8, 2012 Share Posted July 8, 2012 The book and blog look very interesting, even for non-dob users. Link to comment Share on other sites More sharing options...
