Daystar Filters ' 130mm-Aperture Energy Rejection Filter is designed for on-axis use with Refractor and Maksutov-style OTAs to reduce the heat load on your filter assembly by absorbing or reflecting UV and/or IR light while transmitting light in the desired spectrum. This ERF can be used with H-alpha, Sodium, and Helium D3 solar filters, but is incompatible with calcium wavelengths.

Choose the ERF aperture size to approximately match your refractor's objective aperture or Maksutov corrector plate. Select the correct filter cap size by measuring the outside diameter of the OTA's dew shield and choose the ERF with the smallest inside diameter that will fit over the dew shield. A set of screws is included to secure the ERF into place. This ERF's cap has an inside diameter of 16 cm (6.299").

Great addition to my sewing table!
I ordered two of these to give me a little more room on my sewing table. One for the backside and one for the left side. Worked out great! Very sturdy and not hard to install (followed directions). I just extended when I need room and fold when not in use. I would recommend these to anyone who just needs a little more table/room.

Not very sturdy
The oak that this is made of is very nice. The little bit of extra counter space is nice. The problem is the bracket to hold it up is kind of small and flimsy, so the shelf won't bear much weight. It will be ok for putting light things on. Also had a problem getting it to hang flat in the down position.

Don't know about these items and ratings have nothing to do with product because the next day air has been sitting in the UPS building for a week now.

No quality control.
Look at other options. Received with hinge already attached to the wood, at an angle. Tried to contact seller, no response. I fixed it myself. Rather than having hinge attached they should just let the buyer install the hinge. Made in Vietnam.
