Peter,
It would be good if you could make a seat that could be used on the
ladder. One that could be moved from rung to rung as needed.
I've been using a heavy duty 4 food wooden ladder for years. It's held
up well. It's a little heavy but the weight is an advantage on a windy
night. I don't have to worry about the ladder getting blown over when
I'm not on it. The problem is finding a heavy duty wood ladder.
Those fiberglass and aluminum ladders are nice. If you were going to add
extra rungs, maybe a piece of wood either on the outside or the inside of the
fiberglass would help with a more solid attachment point for the rungs.
If you plan to share views other folks, you might select a ladder that can
handle someone pretty beefy. Not that any of us are "beefy".

Jim,
I think I will keep my 6 ft. ladder and add a rung between the fist and
second rungs for using with my future 24² Dob. The 24² f/3.7 Dob eyepiece
height will be 88 in. straight up and between 80 and 84 in. when angled 15
degrees from the zenith. My 6 ft. ladderıs rung centers are 12 in. apart
and I need one placed in between the lower two rungs to get my eye
comfortably at the 84 in. eyepiece height. I thinking of using a piece of
2x4 screwed in. That should support my weight. Do you have any thoughts?
I like using ladders it offers a good way of resting as you lean on them
and observe. I get tired of standing up to the eyepiece for hours while
observing.

Peter:
I use a 5' ladder with three wide/deep steps on it (more comfortable on the
feet than the narrow wooden type).
It also has a tray, into which I inserted an eyepiece and accessory rack.
Weight around 25lbs. Got it at Ace
Hardware for around $40 or so.

Hi TACıos,
Iım wondering if anyone has experience with and/or currently uses a
astronomy ladder in observing? This type of ladder has less space between
the rungs, around 8 inches spacing for a more comfortable observing
position. They are also designed similarly to orchard ladders by using a
single pole opposite the steps for placement on uneven terrain.
