Celestron Heater Rings - (Various sizes) telescope for kids Photography of (small) brighter nebulae

Photography of (small) brighter nebulae and star clusters without power-consuming cooling - exposure times of up to 2000 seconds are possible

The working distance or backfocus from the 2" receptacle is long enough to use 2" star diagonals

such as APO's

the combination of quartz glass mirror and carbon composite tube makes a readjustment of the sharpness obsolete

larger ball bearings are used like in previous models to increase accuracy and payload capacity
