The amazing patent pending SCT RICHFIELD STAR*SWEEPER™ turns your F/10 SCT into an F/5 or faster GIANT BINOCULAR and allows use of any manufacturer's 70 degree or 82 degree 1 1/4" eyepieces for monster fields of view ($149). A pair of 16mm Nagler Type 5s for example, act like a pair of 32mm Naglers and are FLAT and SHARP across the field of view. Here is some feedback that came to us last night:
In the mail a few weeks back arrives The new Denkmeier F/5 Star-Sweeper reducer with a two inch adaptor made to use with my Deepsky Binoviewer. The 39mm reducer is in a beautifully machined two inch anodized cell threaded to accept 48mm filters. This can be unscrewed from its two inch adaptor. The two inch setup gives you a nice secure setup using the binoviewers.
I could bore you with descriptions of beautiful vistas seen while looking through wide field views but I'll let you discover that for yourselves. I would like to compare it to the other correctors I've used.
The Celestron F/6.3 won't work with the binoviewers because they screw in the back of the SCT. The Lumicon F/5 works OK with the Binoviewers but seem to lose contrast toward the edge of field. The Star-Sweepers are simply magnificent, sharp with noticeably more contrast across the field of view. The coating on the Star-Sweeper may make the difference, very high quality.
Conclusion: At first I was concerned as I thought to myself "I guess I'll have to purchase another reducer", but to my delight I am able to use the Star-Sweeper as my main reducer with or without the binoviewers. So I'm selling my other reducers and keeping this one. Using the Star-Sweeper on a C14 is like having two scopes in one. Does it work on this scope, you bet it does. The views on the C14 at low power through the Deep-Sky binoviewer and Star-Sweeper is one of those pleasers that everyone should experience. I truly believe this is an essential accessory for this scope. Thanks again, another winner.-V.C.
