My old 8-inch Celestron SCT just fit in the larger space. I used the smaller space for accessories; finder, Telrad, etc.
It may not look like much, but this is a very well made case, approved for shipping on airlines set by the ATA (Air Transport Association) specification 300, category 1 guidelines).
These are the type of cases designed to use when shipping expensive, fragile equipment such electronics, musical instruments, and yes, telescope OTA's. Latches are recessed. Corners and ALL edges are steel reinforced. Heavy duty rivet construction. Hinged lid. -- Virtually UPS abuse and air frieght handler proof. Sidewalls are plywood, lacquered. The foam is getting a bit ratty, but could easily be replaced.
$70 + actual shipping, CONUS. Payment via Paypal preferred, but will accept money orders. No personal checks, please.
