There’s no need for them to be perfectly parallel. If it weren’t for atmospheric refraction, flexure, and polar mis-alignment, you could simultaneously image two completely different parts of the

BrianI've used polemaster for a couple of years but a recent comment that it wasn't accurate enough for astrophotography got me to compare it to phd2 drift method. Polemaster was darned close but phd2

Don't let these guys talk you out of the polemaster. it's really great and perfect for lazy people like me :) .... er maybe I should say perfect for people that want to spend more time imaging :) i do

This may not be the right place for this question but a recent post talked about side by side saddles and it raised a question. If you had a side by side or piggy back, say a c11 and 80 mm refractor,

Thank you, Brian, and others for your input. I used to do polar align manually using the Kochab method and looking through a polar scope (ha - please don't laugh) actually, I had it down to a science

Hi Donnie I have the Skywatcher 120ED Esprit, in fact it's imaging in my driveway right now as i write this :) Is there any reason you wouldn't just go with a G11G? it's more than enough mount for the

My observing will only allow me to set up and takedown for like one evening of observing or AP. Then it might be another week or 2 weeks before I can bring all the equipment out again to set up.

Donald, You might want to check out ADM accessories, too. I bought a mount that fits on the dovetail of my OTA. The Polemaster is smart-enough to figure things out even if not attached to the RA axis.

Can't blame Mark for finally doing this. He's been doing an amazing job, all by himself, and as I understand it, not getting paid much for his trouble. It's nice of him to grandfather in the existing

This is my first post and I have been doing a lot of reading and some research on the Titan as a most likely purchase at some time near future.? I have about 3 years of experience with another

Another great add Paul! you're on a roll today!! :) -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

Robin's cousin, Tom appears to be still in business making them, and at least according to the website, some of the accessories are shipping rather quickly: https://www.bndastro.com/Default.asp

Robin made and sold tons of great accessories for the G11, including stainless steel weights, which were expensive and popular but alas, they are completely sold out -- Brian Brian Valente portfolio

Thanks to all of you. I really like Paul’s link. Exactly what I was looking for. It even has the G11 dimensions to calculate moments from the weights.

great add Paul! I totally forgot about robin cassidy. I own many plates and dovetails from him, sad to see he passed along the business but it still seems to be going -- Brian Brian Valente portfolio

Thanks Paul sounds like many business that bring you ?then change to a dollar value it’s the way of them all. keep up your good work Paul. -- Brendan
