Part # 5020 Anti-reflection Sheet

If the customer purchase astrograph set which doesn’t use drawtube, the pre-cut sheet is set inside tube. Now extra ones are available as option. Part # 5020 at $8.00 It includes 2 sheets of 130 mm x 240 mm. 240 mm is the length of Series 80 tube’s internal circumference. So you can just cut the length to apply.

5020This is high-quality resin-made (not paper!!). So unlike paper-based sheet, it’s solid and reusable even after removed. Sided-tape should be used with.

The same material is also preset inside drawtube section of FTF-M57 provided by Hutech. See my previous page.
