Product Info
Manufacturer Description
The Meade f/6.3 Focal Reducer/Field Flattener (4-element, 41mm diameter, multicoated lens elements) # 07545 threads on to the rear cell of any Meade SCT telescope or to other Schmidt-Cassegrain telescope brands. It reduces the telescopes focal ratio by a factor of 0.63. With this accessory, f/10 telescopes are converted to f/6.3 and f/ 6.3 telescopes are converted to f/4.
Simultaneously, it helps to flatten the field, significantly improving edge-of-field corrections. The f/6.3 Meade Focal Reducer enables a reduction of photographic exposure times by about 50%, while producing an actual field diameter of 1.5" at the film plane. The f/6.3 Focal Reducer duplicates the rear cell thread of the telescope, allowing you to attach all standard rear cell visual and photographic accessories. Has a standard male SCT thread (2" outside diameter x 24 TPI) on one side and a standard SCT female thread on the other.
Product carries full one year Meade factory limited warranty (within US/Canada only).

Jan 2, 2017CPC800 focal reducer/field flattener
Pros: Cons: Comments:Being new to astronomy, iI was a bit skeptical if i should spend another $100 on this focal reducer, since i spent many other hundreds on optical accessories from Baader,TeleVue etc. With this device the planets look much brighter and clearer, and its alot easier to see as everything is more bright !
Bottom Line: Would you recommend this item? Yes
This is a great optical piece and i am very happy with the purchase.This review was provided courtesy of AgenaAstro.com

First, I read comparisons and reviews about focal compressors. Some were more expensive, some had another focal compression rate. I had to find optimal price/compression ratio.
In Russia, where I live, astronomical gadgets are expensive, and I started to search in foreign shops.
And I found this shop, where was focal reducer with good price and worldwide shipping.
I received my item after 2 weeks. For Russian post service it's very good.
Now I use my compressor with handmade adapter and everything is good.This review was provided courtesy of AgenaAstro.com

Feb 8, 2013Focal Reducer, What do they do?
Pros:Strong Construction,Quality Lenses,Accurate,Lightweight,Easy to Use,Compact
Cons: Comments:Several things, actually. First and foremost, they reduce an f/10 SCT to f/6.3. For the CCD imager or astrophotographer this actually means two things; dramatically shorter exposure times, and a distinctly flatter field. Said differently, they add corrections to put much more of the field in critical focus at the same time than would normally be the case with a SCT without a reducer/corrector.

Nov 5, 2011Perfect complement for a SC f 10
Pros:Quality Lenses,Strong Construction,Compact,Easy to Use
Cons: Comments:This is a perfect optical complement for a classic SC f10 telescope. I like to photography the full moon, and with this item, the whole satellite enters in one frame. Besides, the optics are good, you don't loose any quality. Very recommendable.
