Back to basics.

Hi,

Haven't done any self build stuff for a couple of years.
I needed to make a barn door tracker for some nightscape photography at a bed & breakfast that has a lake and beautiful gum tree's around it. and wanted light and portable.

So here's the result, ( see images )

The main component in this build is the interlocking aluminium, this over comes any flexure and twisting.

I plan on using focal lengths from 18 to 50mm with this setup, and a max of 5 minute for subs.

Cheers,

Justin.

Sometimes simple things have big rewards. Good luck with it Justin, hope it works as it should.

Thanks Andrew!

Yep I agree, had thoughts of using a motor drive but decided to go for simplicity.
Back in the 90's I built two motorized trackers, both with drives, they were somewhat over engineered, ended being too heavy and rather large.

Cheers,

Justin.

And cheaper than a polarie.

Should work well !

I have a Vixen SP mount of over 20 years old which still works flawlessly even without guidescope and using 300mm max 5 minutes. I use this setup during overseas trips as well.
