What to Compare Before Buying
- Aperture size: Measure the front opening of the telescope, binoculars, spotting scope or camera lens and make sure the 100 x 100 mm sheet gives enough overlap for your planned cut.
- Instrument type: This sheet is for the front of optical equipment, so check that your setup lets the filter sit in front of the objective.
- Pack format: It is a single flat sheet rather than a pre-made mounted filter, so factor in any cutting and fitting you want to do yourself.
- Viewing purpose: It is intended for solar viewing and photography, including the Sun, sunspots and eclipses.
What Else You May Need
You will need suitable scissors or a cutting method for trimming the sheet to size, plus whatever mounting or retaining method you plan to use on the front of your instrument.
Before You Decide
Check the exact size of your instrument’s front opening, confirm you want a cut-to-fit sheet, and make sure the filter will sit at the front of the optics rather than behind the eyepiece. The pack includes one sheet and printed instructions.
