finderscope bracket ok for guiding?

[Astronutjob]

hello i am planning to use an qhy5 to guide through my finderscope is it ok to use the normal bracket that comes with the SW finderscope as there is a spring loaded holding screw on it, if its not what do other people use?

I use the same bracket to hold my 50mm finder and QHY5, but i was'nt happy with the spring loaded pin, so i removed it (awkward little devil it was too) but it came out and i filled the hole with Araldite, let it set good and strong, and tapped it out with a 6mm thread, fitted a little plastic pin; good as new and it holds the finder just fine.

I use the standard finder bracket with a QHY5. Not had it long, but it seems fine. I get decent round stars at 5min, which is as long as I need to go. LP washes everything out after that.

I've used it like that and always found it OK, though considering what else can go wrong what libraryman says makes sense for peace of mind.

Ok thanks for the info my worry was it would cause flexure or move slightly whilst guiding, how do you remove the spring loaded pin?

[libraryman]

Anchor the tube in a vice (NB not by it's dia), protecting the edge from the jaws, don't need to go too tight.

Just prise out the spring etc then drift or drill out the cylinder, fill the remaing hole with rapid Araldite, put it somewhere warm to set for 2 days.

drill out a 6mm tapping size hole (4.8mm) gently tap the hole.

Plastic pins from e-bay.

job done, easily strong enough for a guide scope or finder.
