Hi.

 

I just found an used SkyShed POD XL3.

I was wondering. Is it still possible to point your telescope at zenith the way the top opens?

And related to that. Should the mount be centered in the observatory, or does it make sense with a bit of offset to get a bigger field of view?

 

THX in advance

It's common to offset the the pier.  Mine is 12" southwest.  With a big GEM, zenith might be doable.  The dome lip sticks about 6" past the centerline of the dome.  If your GEM puts you 6" either side of the mount axis, you might be able to reach zenith.  Otherwise, you'll be a few degrees off and have to wait.  I now run a C11 beside an 80mm and that's on a pier high enough that I can see over the walls horizontally.  I'm inches from the top of the dome and that is an problem often enough that I use a DIY PZT so I can push the dome all the way out of the way and that solves all issues.  Look at PZT on the POD website.  Also several examples of various PZTs with a google search.  The POD is the best accessory I've bought and I wouldn't trade it.  With a PZT, it does everything I need economically.  The POD website also has a graphic calculator that lets you input your mount/scope dimensions and it shows how things fit.

Thanks smile.gif

 

A DIY PZT seems like a great idea.

I only need to order 3 quick release brackets for it to work.

I think I made quite a bargain. I bought it for 500$ without seeing it i real life.

After some cleaning it looks just like new.

I will build my PZT out of plywood and cover/waterproof it with a layer of glass fibre.

Sky Shed now makes a roll off table for their pods so you can roll off the dome.

Wondering if anyone else is having a problem getting those Sky Shed brackets? Still waiting for the ones I purchased over 3 months ago. Is there a manufacturing issue? They shouldn't be that hard to make with the proper machining equipment.

Congrats on your new POD. The answer to your question depends on a few factors. What is the size of the OTA? A large SCT will have more chances to be obstructed by the dome when pointing at Zenith. Is the pier offset? If you won't be doing any observing I would offset at much as possible, the recommended is 10-12 inches. Finally, as a POD owner, I highly recommend a PZT, even if you come up with your own idea because, for imaging, there's nothing like moving the dome out of the way and just image without worrying about obstructions.

I hope they get around to it. First obstacle is finding a way to get them shipped to Denmark. I am in contact with Wayne. Hope it works out for you (and melol.gif ).

I built this out of plywood and gave it a few layers of epoxy to make it waterproof and slide like a dream. The table is facing north and wide enough for me to polar align from the middle of the observatory.smile.gif
