"it even improves the image quality"
Adding extra glass in the light path will not improve image quality. The extra magnification may give you a better image if you have not exceeded the maximum resolution of your scope for the given conditions of the night.

I dealt with Harry Seibert many times in the past and the last time was not a pleasant experience. He failed to deliver multiple items by the promised delivery date even with months of advance notice of when I needed them by. This was not a case of missing parts as he had everything he needed to complete the project. When I grew angry with his constant delays and excuses he threatened to keep my equipment. (My eight inch refractor lens, and TAK focuser)

All I can say is buyer beware. I would use paypal if you must deal with him.

Hi Walt,

Denkmeyer went through a number of optical correctors for use with their binoviewers. I do not have that particular piece in my collection but I have similar devices. The advantage of that device is that it allows you to come to focus in probably most refractors. If you truly have only 1.5 magnification then that is a good adapter. The challenge in getting binoviewers to focus in many scopes has always been the amount of magnification that the OCA adds to the setup. The best unit I have ever found is 1.35 so you are pretty close to that.

You are wrong.
