Discovery Truss scopes...

Posted By Chad Cummins
I have had one of the first Starmaster scopes and am considering a bigger scope. Has anyone made the move down to discovey scopes from a premium dob? What was your impression? How have the optics been lately? They are really a great deal and I am most interested in the 15 and 15 inch versions... Thanks

Which Binoviewer?

Posted By Chad Cummins
I have a 12.5 EL starmaster and a 3" flourite refractor. now that the latest models are out who makes the best package for me. And is there are perfomance difference between 22mm prisms and 26mm prisms. Please no flame war just interested in your thoughts before I lay my money down.

Thanks

For OCA users only...

Posted By Chad Cummins
With every effort to avoid a flame war did you BK bino guys know that you can remove the bottem off of a 2X shorty barlow and replace the lower element of the OCA and get a 2.5 X OCA.... I tried it last night and had to mess with the spacing to get the focus point right but it worked. Still don't have a detailed report on my BK bino because it was too cold to wait for my mirror to cool... Indianapolis was 18 last night....

Good 10 mm bino eyepieces...

Posted By Chad Cummins
I need to get some low power eyepiece pairs and I am not looking for nagler prices... Of the Orion brands do any of them approch the Ultima/ultrascopic level. How low do most binoviewer guys go in focal lenght?

Thanks

An old AP 400 with quartz drives.

Posted By Chad Cummins
I am getting a new AP and am looking for a mount. Where the old Ap 400's (from the mid 90's without goto) as high quality as today's? How would it compare to a new GM-8 or even some of the Vixen equipment?

Thanks

Anyone do any real science from home?

Posted By Chad Cummins
I am just curious if anyone in this group is doing any spectographic analysis or anything that they publish. Variable stars? Just wondering really if outside of comets what else people work on or discover...

siebert contest guess

Posted By Chad Cummins
My guess is that it contains the negative doublet that can connect to the front of the binoviewer by itself(2x). Then can be used with the standard OCA(1.5x). There is a sliding internal double (I am guessing the negative one that is on the lower side of the adapter that can move the negative elements farther from the reducing elements. to acheive the other magnifications.

Yeah when AP starts shipping out scopes it seems that the “Off” brands (TEC, TMB, Tak) all start appearing but the new in the box AP stuff is even more surprising.
