CCT-32
STANDARD OPTICS:
Our typical 0.8M Classical Cassegrain has an F/3 primary mirror with an effective focal ratio
between F/8 and F/18. The 125 mm field is fully shielded and unvignetted.
Both primary and secondary mirrors have a near zero expansion substrate
Back Focus is 28 cm from mounting surface
2 variable, low voltage power outlets for reticles provided on optical tube assembly
2 AC power outlets on optical tube assembly
Finderscope: 5 in F/9 with 2 in. dia, 32 mm focal length eyepiece and projection reticle
TELESCOPE MOUNT:
30 in. diameter friction drive in RA and 28 in. diameter friction drive in DEC
Open structure optical tube assembly affords better
"seeing"
Steel mirror cell with multiple 12-bolt patterns per KPNO standard
Tracking accuracy: +/- 0.5 arc seconds in 5 minutes, +/- 5.0 arcseconds in 1 hour
Pointing accuracy (with refraction and alignment correction) better than 30 arc seconds RMS
4 deg./sec. slew rate
Variable set, guide and tracking rates: 0 to 4 deg./sec.
Epoxy paint for durable, functional appearance
Supports 100 kg instrument load with CG 36 cm behind mounting surface
