Solar Filter Lookup Tool

You can use the table below to find a suitable solar filter for you telescope.

This table was compiled by Agena AstroProducts using many inputs from companies and individuals (thank you!) and a lot of cross-referencing. While we believe that this compilation should be accurate, it is based on data provided by others, and we have no way of verifying if every combination below is perfect or not. Hence, please use this table as a general guide. It is still your responsibility to measure your telescope’s tube/dewshield size and compare it with the specs of the solar filter.

If you do not see your telescope listed below, please contact us with careful measurements of the inside and outside diameter of your telescope tube (preferably in mm), and they will be happy to look up what might work.

See errors below that need to be corrected? Know tube dimensions or have telescope-filter compatibility info not listed below? We’d love to hear from you and add to this table for the benefit of everyone. Thank you.

Filter Fit Notes

  1. 1. Fits the inside diameter of telescope
  2. 2. Works with optional 20mm screws sold by Agena
