Re: Installing a new dovetail base for finderscope
Soooooo my concern now is the protrusion of the lock nuts. Will they enter into the line of sight? I will find out when I take it out and align and sight it in. I don't want to do that until the kids go back to school here which isn't until next Monday

Re: Installing a new dovetail base for finderscope
That is what I did do. I used a black permanent marker not only on the lock nuts but also on the ends of the screws.Lady Fraktor wrote: ↑Mon Aug 19, 2019 6:52 pm Any bolt/ screw/ nuts inside the tube can be blackened with a sharpie or a touch of paint just make sure there is no light scatter from them.

Re: Installing a new dovetail base for finderscope
I think this may be a good thing for now I will learn exactly how it works.
When the declination is locked down the fine control works off of a fixed plate with the slow motion adjustment screw being on one side of the fixed plate and a spring piston pushing against the other. It looks like even at its max setting you only get very limited motion (not 360 like with Right Ascension). Declination isn't what you track with anyway. Fine adjustment Declination is just for pinpointing once you are already there. Now I have to figure out the nuances and if or how it will get in my way.

Re: Installing a new dovetail base for finderscope
B = Slow motion screw
C = Sleeve
D = Set plate base
E = Piston
F = Spring
G = Spring tension & play amount bolt
It has been all go here. The set screw for the slow motion cable came out and fell on the floor after ricocheting off of a tripod leg. I didn't think I was going to find it but I did.
I had to figure out the best setting and how to achieve them. Things like at rest / storage you want the least compression on the spring but when used you want full functioning play. This declination slow motion only gives you 5 degrees of motion. That is only about 3 full turns of the slow motion control cable knob.

Re: Installing a new dovetail base for finderscope
There are all kind of astronomy awards give out but I don't think there is any for being able to pilot a telescope correctly. There should be like a set of wings like aircraft pilots get. There would have to be some proper instruction set up first and I don't think there is any.

Thanks. I want to take it out during the day to align and sight in first and that wont be until at least Monday when the kids start back to school.
Later tonight might be good and tomorrow is suppose to be great for viewing but I will have to use something else.

Re: Installing a new dovetail base for finderscope
The thing is, is that I can't do like most of you do with sighting it in and leaving it sit until used at night. I reside in a very bad place were something like this can not be left outside. I have to assemble and disassemble it with each use. I sighted it in then disassembled it and bought it back inside. I can only hope that the sighting in alignment stays true through taking it back out and putting it back together.
