Good Morning All,

I received my C90 and am impressed so far with it for Grab and Go Purposes for Land and Sky viewing. I am now wondering if there are any benefits(image quality) to be realized by upgrading to a set of different diagonals for Land and Sky use.

If so, can you recommend some models of diagonals to consider?

Thanks in Advance!

Tony

Mounts Questions & Expirience / Favorite entry level GOTO mount?
« on: December 29, 2017, 03:22:21 AM »
I have always observed with EQ/RA drive mounts or push-to so I know very little about this. I have a friend who is considering a 1st family scope and is interested in GOTO. She is a teacher with two boys 10-12 and lives in SoCal with heavy LP. A basic database of brighter objects is probably fine as they will never see 12th magnitude stars from here. I have seen posts with people doing a lot of hand-wringing over certain setup or software issues with some designs so that should probably be avoided. Her budget is $700 so she should be able to get decent optics and a solid mount. I expect it will mostly be a backyard scope with some possible camping trips to darker skies.

* Solid mount and quality optics for general observing. Limited DSOs from the city.
* Simple and reliable setup and alignment.
* Self contained power supply so no wires or extra power needed.

Anything else to be considered? I have seen many Nexstar setups and most seem to work fine until they hit a snag. Troubleshooting them seems fairly complex. I am familiar with Orion mounts, and the recent ioptron AZ mounts look interesting. I have never actively used any of these.

Mounts Questions & Expirience / Vixen GP Mount with DD-1
« on: December 28, 2017, 11:05:20 AM »
Hi

Yesterday I became the owner of a beautiful looking Vixen GP mount with DD-1 control unit. I got a copy of the manual that was downloaded from the Internet. Would anyone have a more detailed copy please? The manual with me does not give any technical details of how the mount is put together, etc. Yesterday upon bring it home I observed that the gears on both RA and Dec motors were not engaging into corresponding gears on the drive. It took me some time to figure out the cause and I fixed it (I hope). That made me wonder if there could be more similar corners that need attention.

This particular mount was in storage for the past 6 to 8 years. It is possible that the mount has dried up and needs some lubrication? My copy of the manual does not talk on this aspect. It is possible that it needs some fine tweaking to make it work properly. I do not know. Is there an expert who could advice me?

Any help is immensely appreciated,

Beginners Forum / Star Test.

Forgive me for not searching the forum...What should I see when doing a star test with an Orion XT8? There is a picture floating around out there somewhere? This morning I would go out of focus both ways and I would see a fuzzy disk with the exact likeness of my mirror.
