    450nm for astronomy pointing?

    Hello, sorry just wanted to know what is focusing to infinity?

    1.4w 445nm LP

    Aha, thanks. Are these universal/set sizes? Or do I need to look for a size in particular for mine?

    Just whilst I'm awaiting the delivery of these springs, can I buy a bigger focus ring? Are they set diameters etc?

    I'm going to order some of the internal springs from the link given and see how they go :D

    For Sale: Internal Lens springs

    Hi, how much for shipping of 4 of these to the UK?

    Thanks, I'll contact the OP of that thread and get some ordered. With pressure forcing the lens and focus ring outwards, I'm worried that through twisting to focus too much the whole unit gets thrown outwards and lost? Or am I just being paranoid lol

    Okay, I bought some teflon tape (which I found out is a trade name for PTFE tape) and wrapped a piece around the lens thread once. It screws back in much sturdier however if I unscrew the focus ring, the ridged ring unscrews itself from the lens thread as the teflon tape keeps that bit in...

    Aha, thank you! I'm gonna get an assorted spring set from the local hardware store and hope that at least one of them will work well in terms of size for the internal and external spring

    Let me see if this is right: The internal spring goes inside the hole between the focus ring and lens mount thread, and the external spring goes around the lens mount thread?

    What's the difference between the external and internal springs? I.e. where do they both go? One of them go around the lens mount thread I know that much

    Thank you for clarifying that! I'll order some teflon tape off the net. I've attached a picture of the thread that needs a spring around it, will this need an external or internal spring? http://www.nugget.org.uk/storage/lp%20lens%20mount.jpg

    At present, when I twist the focus ring too much, it comes out (unscrews) and there's no spring in place so I would assume it is the External Lens Spring as you have linked to: External Lens Spring I will for the time wrap some teflon (which I'm sure is what I call electrical tape) and order...

    So do without the spring and just find some teflon tape to wrap around the lens mount thread and then screw it back in?

    1.4w 445nm LP

    I have just acquired a pen as described in the title... anything more technical about its components and I don't know. It has a focus ring on it and I was just wanting to know, when I twist the ring to focus (too much and it unscrews itself off), but when I twist to loosen it, it becomes...
