The Meade LX200/RCX400 Deluxe Astrophotographer's Kit has several valuable parts for serious astrophotography; the f/6.3 focal reducer/field flattener for better imagery, a Series 5000 2x telextender, a 9.0mm Plossl eyepiece with an illuminated reticle, a variable-projection camera adapter for fine-tuned SLR photography, the #647 flip-mirror system for quick changeover between observing and photography and the #895 vibration isolation pads for enhanced sharpness at all magnifications.
You'll save approximately $260 by purchasing this kit, as opposed to collecting these pieces individually.
