Condition:
This is a Radian 61 triplet APO with the included flattener, in good condition. There is some minor dust on the inside of the objective that will not significantly affect your data collection. The flattener, however, is clean. Additionally, this scope was definitely used by its previous owner - the body does have some nicks and scratches.
It comes complete in its original padded backpack and box.

High-Quality Glass
The Raptor 61 features an apochromatic triplet optical design with premium glass and multi-coatings to tackle chromatic aberration with ease, leading to an ultra-clean overall image without the nuisance of reflections.
Wide Field of View
The 275mm focal length is simultaneously excellent for widefield imaging and highly forgiving, making it the perfect choice for both beginners and experts. Targets like the entire Veil Nebula and the Orion & Horsehead Nebula together can fit easily into frame on up to full frame sensors.
Dedicated Corrector
With the Raptor 61, there's no need to buy an additional reducer/flattener. The dedicated, factory-matched corrector that comes as standard is intended to be used as an always-on solution for imaging. The corrector's three-element design provides correction for sensors as large as full frame, so no matter which camera you use, pinpoint stars can be seen across the image.
