I use the WO Z73 on this mount exclusively now... not sure what I’ll do with the 500mm mirror lens.

davidparks,

 

Very nice setup!

 

Can you comment on the wedge(s) you are using?  Looks like the earlier photos of your setup have the Sky-Watcher wedge, but the last photo indicates an Ioptron EQ base?

 

Do you prefer the iOptron over the Sky-Watcher wedge?  Also, can you provide a link to the wedge?

 

Thanks!

David, (@davidparks)

 

Now I am getting into this setup too! (with my Nikon 300mm/f4 and DSLR). Some 3D printed bracket like the following by Philippe Leca (I am a fan).

There are 2 key things to run this in EQ mode - Polar Alignment and Star Alignment.

 

  1. You mentioned before that the Polar Alignment could be "easily" done by using drift alignment with SharpCap. Could you elaborate in detail how it's done?
  2. For the Star Alignment, I think eventually I will do plate solving and sync. That will be very easy with AF. But without AF, finding a bright star to do manual focus will be extremely important. So I guess the initial star alignment will be very important. How do you do it with AZ-GTi?

 

Thanks in advance!

Ulmish, yes you are correct, I’ve switched from he SW Latitude Base to iOptron’s Alt Az Base.  They are very similar, and although I was very successfully using the SW product, I do find the iOptron base slightly more stable with my equipment.  The iOptron base is slightly shorter, with a wider altitude hinge, and this may account for the additional stability.  Others have reported just the opposite, finding the SW a bit more stable than the iOptron, so it may depend on luck of the draw.

mxcoppell,  I think this post explains for the most part how I do the Polar Alignment and then Star Alignment

 

Nice setup with that 3D printed bracket.  The 300mm lens should provide a great FOV!

Thanks, David - I appreciate the additional info.  I have an Astro-Tech AT72EDII on order, and this mount looks perfect for a grab-and-go setup.

Hello! I am so interesting. To buy AZ-GTi or Sky Adventures for mobile astrophotography. My main scope - Tak FS60CB and Canon 6da. (255mm f/4.4) It's weight is 2,5 kilos. Would you recommend me buy AZ-GTi over SkyAdventures? 

For me it's so important to use Skysafari app. it's great thing!

I would definitely go to AZ-GTi route. Star Adventurer is very capable but it's also a pain to use when "go to" a target in the dark. If I start over again, AZ-GTi EQ mode for the >200mm focal length is a non-brainer.

Received the bracket with guider support from Philippe Leca. Better than I expected.

Very strong material and stable when all gears are put together. The total weight is just 6.5LBs (2.95KG). Perfect for AZ-GTi or SA. 

 

- Nikkor 300mm/f4 AFS

- Nikon D500

- Orion 50mm Guiding Scope

- Orion SSAG

 

Just to share.

Hate to bring a dead thread back to life,  but wanted to follow up and see if others are still moving forward with this project?  I am in the process of purchasing the AZ-GTI with the hopes of using it as my travel rig.

Well I bought the iOPTRON skyguider PRO with the ipolar scope but what a pain at night for having to "Goto" a sky object.  Am thinking of selling it and going with this mount.  I want something light weight and easy to move with....
