Here's my Tamron 150-600 lens with a 2.0x matched Tamron telextender mounted on my 8" Meade LX200 Schmidt Cassegrain scope:

 

I have a C5 Celestron with a camera mount. Many years ago I had a C11. It was fun until you figured out the stars never change. Sold it back in the 80's.Nice looking set up you have there. What do you use it for?

 

Checking up on the neighbors? Ok. OK.. j/k LOL.

 

I was going to say " quite the set up to peep in on your neighbors but you beat me to it.

 

I have the same lens. I need to use a tripod or a monopod as the lens combined with the camera are HEAVY!

 

Get yourself a Really Right Stuff head. They make them for tripod and monopod. I have one of each and can't imagine without them for the long lens. Gitzo makes some fine tripods and monopods as well.

 

The LX 200 is for Astronomy. With the GoTo database the scope can find, center, and automatically track over 100,000 objects in the night sky. I like to sit down with star charts and set up a suite of 100 or so objects for a night of viewing. The stars never change, but the viewing changes dramatically with the seasons.

The Tamron setup on the scope with a Nikon 3400 is for solar eclipses. We've seen and shot total and annular eclipses in Roundup, MT. (51 miles north of Billings), Cabo San Lucas, Santa Catalina Island (off the coast of Los Angeles), Aruba, Munich, Puerto Vallarta, St. George, UT, and Salem, OR. We're doing an annular eclipse in Utah in September and a total eclipse in April 24 somewhere near Dallas in April 24. We're staying in Dallas with my best buddy who just moved there after his wife's promotion with T Mobile. These eclipse trips have had/will have interesting vacations wrapped around them.

 

That's one reason I haven't gone bigger on the zoom lens. The weight. I can't see me lugging much more weight than my current camera and lens while walking in the woods, hoping a bird jumps out at me.

 

RRS make some of the best stuff.
