Askar 0.74x Reducer for 111F
Askar 0.74x Reducer for 111F
Get the results you're after faster and increase your perspective, with a premium astrophotography reducer! Built for the Askar 111F, this reducer retains the quadruplet telescope's stellar full-frame coverage and great images, while pushing the refractor faster. Take your telescope's performance a step further, with the Askar 0.74x Reducer for 111F!
This reducer's 0.74x reduction factor gives your Askar 111F Flat-Field Refractor a big speed boost, taking the stock f/6.9 766 mm optics down to f/5.1 and 567 mm in focal length. This faster effective performance brings you the same amount of light in less time, or more data in the same amount of time, making incredible astro images even more accessible. Wispy nebula detail appears sooner, and with triplet optics performing the reduction, these details will be clear, contrast-rich, and detailed. This reducer requires backfocus for these incredible results, but with a design setting this at the industry standard 55 mm, builds are still very easy to assemble. This reducer maintains the Askar 111F's full-frame sensor coverage and superb field-flatness, ensuring you can continue to use the same camera. This design is all built into a CNC machined metal housing that provides a rigid and robust bridge between your telescope and imaging gear.

Triplet 0.74X Optical Design
The Askar 0.74x Reducer
for 111F uses a triplet optical design to speed up your astrophotography.
These three optics take the
Askar 111F Flat-Field Refractor's stock f/6.9, 766 mm focal length view to f/5.1, 567 mm. This brighter
view maintains a 44 mm image circle and flat field, for images that shine
with sharp & contrast rich performance from full-frame corner to corner.
Simple to Use, Premium Construction
This reducer
features M68 connections on either side, with M54 and M48 adapters included
to connect this to your 111F telescope and imaging train. This reducer
re-introduces backfocus, however with a design around the industry's
standard 55 mm, constructing an imaging train is still easy. This reducer
additionally features a 2" filter cell that simplifies giving your image a
boost. The reducer features a CNC machined housing for rigid and robust
addition to your telescope, and comes with two dust caps to keep the optics
protected when not in use.
Frequently Asked Questions
How does a reducer work?
A reducer takes an existing
image, and compresses it into a smaller area. This has the effect of
increasing the field of view, bringing part of the image that was previously
cut off into view, and increasing brightness through this concentration of the
available light. This compression is why sometimes reducers will shrink the
image circle size. This has the effect of making the telescope perform like a
faster focal ratio design.
