BORG Filter Box

I got several similar inquiries from different customers these days. So I thought I wanted to show some sample configurations here. BORG filter box (#7519) has M57 male and female, which allows for various connections with telescopes and cameras. Here are some.

T-mount connection – from telescope side : 7528 – 7519 – 7923 – 5005

2″ – 7425 – 7519 – 7923 – 5005

For regular t-ring, you may replace above 7923 + 5005 with 7522 + regular Canon t-ring. 7522 has T-thread male. By changing adapters like these, virtually you can attach with any telescopes and cameras. You can replace 7528 with 7424 for SCT threaded connection. Only issue is the light path. 7519 is 15mm long. If someones are looking for simple filter change, this is the solution. The holder accommodates 48mm or 52mm filter. It’s convenient!
