Here's my interest. I'm considering buying a 10" F5 Dob as a complement to my 5"F6.5 achro refractor. I hope to get an equatorial platform for it but in the interest of not overstraining our finances, I'll probably defer the equatorial platform a year and use the time in between to get used to the scope. But I am intending on getting an observing chair if I get the Dob since I figured that I'll need one. Based on my experience with the refractor and earlier times in the hobby when I stood to observe, not using a chair would be for me a show-stopper. I'm much more able to observe, think about what I'm seeing, and write notes and draw it if I'm seated. If I stand, I'm spending too much time fidgeting in an attempt to be comfortable to the point that it's a big distraction on my observing. So if using a chair doesn't work with a Dob, well, it's good to find out now.
Thanks in advance for your responses.
