So MT4, is that your hou$e window bino or your car bino (I'd love to see you try to get that in the glovebox or under the car seat!) Pat
That chair's for my house window. I use a height-adjustable chair, along with a tripod that has a geared center column, for my Kowa Highlander Prominar. Observe right out my window and there's still plenty to see and love. I have yet to take my big Kowa to my main observing site, which is a nearby city park. The bad whether that has persisted through spring and much of this summer hasn't been very kind to me.
For mobility, I use my various 7x, 8x, 10x, 15x (both Maven and Canon) and 18x70.
