Looking to make your Astro-Tech (or variant) scope faster and flatter for photography? Then the .8x reducer/flattener is exactly what your are looking for.

While this Astro-Tech ATRF60 0.8X reducer/field flattener is designed for prime focus astrophotography with the Astro-Tech  AT60ED, it will work with other variants of the same optical tube. Feel free to give us a call if you have a question about your scope if it isn’t an Astro-Tech product. 800-422-7876

The fully-multicoated Astro-Tech ATRF60 converts the 360mm focal length f/6 Astro-Tech AT60ED refractor into a 288mm f/4.8 lens for faster and wider field astronomical and terrestrial photography.

In addition to reducing the focal length of the telescope and thereby increasing the photographic speed, the ATRF60 flattens the normal field curvature inherent in all refractors to provide images that are sharply focused out to the very corners of a large format DSLR chip. Stars look sharp and point-like all the way across the field in your images. You don't have to worry about photos that are sharp in the center and blurry at the edges.

The Astro-Tech ATRF60 reducer/flattener threads on the 60ED focusers. The flattener is threaded for attachment to the telescope via a 54mm metric thread. The camera side of the reducer has 48mm T-threads to connect to a T-ring and camera body. Back focus is 55mm from the shoulder of the reducer to the image plane, the standard spacing for 35mm and DSLR camera bodies.

The interior of the telescope side of the reducer/field flattener is a 48mm female thread so standard 2" filters can thread right in.

Overall rating: 5.0 / 5 from 5 reviews.

Great Reducer

"its a beautiful work of art, I have a past history of machining telescope parts and building mounts dealing with these guys was awesome they look out for there customers I bought both the 0. 8x and the "Field Flattener" and the T-ring to go with my T3i I got a call and missed it, so I called back, The gentleman told me i had ordered the wrong T-ring and he wanted me to get the correct one before he shipped, then to top it off he sent it overnight and i was pleasantly surprised when it showed up early awesome service and of course the weather is not cooperating Thank you very much"

Astro-Tech . 8x reducer for AT60ED

"The reducer allows me to get a notably wider field of view with the AT60ED and ASI533MC, giving nice stars to the edge and no noticeable color issues . The attached image of the Jelly Fish is from the AT60ED with the . 8x reducer/flattener and ASI533MC with dual band filter, ~30 subs at 180 second exposure each in Bortle 9 skies. . . I'm content !"

excellent

"I was on the fence with purchasing this or the field flattener only as there was some chat about spacing being more difficult with reducer. I had no issues with this and the extra fov and increase in light gathering was worth the investment ."

Mike (5/5)

Fantastic Performance and Value!

"I purchased this to use with my WO ZS61 and ASI294MM. The unit is one piece and solidly constructed. Stars look good even to the edge of the image. This is a definite improvement over the AT60ED field flattener due to the combination of construction and faster optics. I see a noticeable improvement with my imaging."
