|Eric's 6" F8 remake continues with the altitude bearings, OTA rings |
and rocker box sides nearly complete. Once completed, the
rocker box sides will be considerably shorter.....
|Wyatt's 10" and Eric's 6" mirror cells have been modified to|
mount onto my mirror board.

|Eric, in Albuquerque, NM, is having his 6" F8 Parks mirror rebuild|
into an ultra-light. Here, the OTA rings include the ETT component as well.
|A 10" and 6" OTA ring for comparison. In the upper photo|
note the 12" ruler on the lower right. The I.D. of the OTA rings is 8"

|Day's 16.25" F4.5 just returned from the coater with|
an enhanced coating and silicone overcoat. Nice!!
|The "mask" is used to place the center "donut" in the center|
of the mirror.
|The "donut" in place. This makes for easy collimation.|
|The 18-point flotation mirror cell was built and optimized with Plop.|
I give the silicone 48-hours to cure.
|The cell will be "firmly affixed" to the mirror -- yet can be removed if needed.|
