72/341 Lacerta Quintuplet Flatfield APO

In this specfic model, the Lacerta 72/432 two-lens ED objective telescope was combined with a 3 lens 0.79x ED reducer/flattener. This 5-lens combination gives 341 mm focus with f/4.7 light gathering power and gives 30 mm corrected wield of view (APS-C format).
The ultra-compact LACERTA 72mm diameter and 432mm focal length is recommended for both astronomy and nature observation, visual work and photography.  Its design (short focus, retractable dewcap) makes it ideal for travelling, hiking, or for quick field trips and sight-seeing.

Thanks to the excellent lens, the image is stunningly sharp and contrasty despite the short focus. The well-proven 72/432 MEGREZ lens was used for the construction. The special ED glass material (FPL53 Ohara/Japan and NBM51 Partner glass) allows the best colour correction currently available in a two-element ED system. The precision Bearing Type Linear zoom lens is equipped with a natural microfocusing unit that rotates along its longitudinal axis.

An aluminium case is included with the binoculars, with space prepared for eyepiece accessories.

The telescope can be mounted on both a photo stand and a telescope mechanism. The Vixen (SkyWatcher) standard prism rail has a standard photo thread at the bottom, so it can be easily mounted on practically any tripod. And the prism rail is compatible with most astronomical mechanics, so mounting is a snap.

Technical data

• Lens: FPL53 glass from Ohara/Japan with NBM51 partner glass (best possible color correction with doublet ED) 
• fast aperture ratio of f/6 with no reducer, f/4.7 with reducer
• excellent optics, usually with Strehl over 90% 
• less sensitive to adjustment problems than a triplet harmonizes well with various field flattening lenses and reducers (see test photos), making it possible to use them with multiple focal lengths screwing the corrector/camera unit to the tube little vignetting and sharp edges with full-format cameras (with flattener) 
• can be used with a diagonal mirror and normal accessories without restrictions, even for nature observation 
• STM coating (STM = superhigh-transmission) 
• eight-way ball-bearing "Octo" eyepiece extension, carries cameras weighing up to 2kg safely and without slipping 
• retractable dew cap, compact for travel (only 310mm short) 
• CNC Metal tube and CNC-machined inner panels
• lightweight and portable (only 2560 grams) 
• Tube diameter 87mm 
• Dew shield diameter 94mm
