Or internal fit for inside your telescope dew shield or a push fit for your lens' filter thread.
Drop me a message for a quote and get that perfect focus!
My replies during the day in the week may be a little slow due to being at work, but I promise I will always get back to you.
Many thanks and Clear Skies!
