Meade DS80 vs concrete floor
Posted 21 September 2003 - 05:26 PM
I was setting up my scope recently when all of a sudden one of the cheap cam-type clamps on the tripod let go. The scope proceded to meet the floor with a heart attack!
The dew shield cracked in three places. No big deal. My problem is the optics seem to be out of collimation.
I read here recently (a few months ago, maybe?) something about collimating a refractor. Nothing in detail, or I would have saved the info.
Does anyone know how this is done with a refractor? Any sites you could direct me to that explain the procedures?
Thank you all for any help you could give me!

My objective is collimatable (is that a word?) but the manual says nothing about it at all.

Now can you tell me what it all means? :o

Anyway, I found some short screws and reattached the cell assembly. It's now rock-solid. Just have to wait for the rain to end to see if there's any improvement
I'll let you know what happens! Thank you!

Just got in from finally testing the scope. Looked good!! Until the clouds asserted themselves!
Gotta move to more scope-friendly climes.
RE: my accident with the concrete. I totally dismanteled(sp?) the scope and tripod, cleaned out the ear wax from the drive motor gears, and re-lubed with SuperLube. Nice stuff!!
Installed two extra screws to hold the optics cell in place.
Tightened up the mount. The tripod and mount still suck!!
Did the easy alignment and the moon came right into the field of view! WOW!!Nice!! Tried Mars, same thing! YOWZA!! Never did THAT before!!! And it was SHARP!!
Mars soon drifted near the edge of field of view, tho. Why ain't it tracking???
The clouds rolled in and I had to pack it up. One leg of the tripod decided to extend while I was carrying it inside. Like I said, the tripod SUCKS!!!
In conclusion, the optics of the old DS80 are nice! Wish I had the DS90, tho. Or even an LX90! But I can dream....

Going up to 90 isn't that big a difference, you might want to consider fixing what you have and save for a 100mm or larger.

Guess not, as the tripod legs were the cause of the accident in the first place
Saturday morning I went out with the scope again but couldn't view much since the clamp on one leg came apart. It's rough trying to observe on your knees!
Thanks for the advice about a 90mm. I'm going to keep this scope and like you said, save for something larger.
