Megrez 80 II SD + APOGRADE dimensions ( not 100% to scale )III. VISUAL AND IMAGING TESTS:At the beginning I did not see a big improvement. But once I run several test both visual and photographical Iwas surprise (and very happy) to find that there was a significant improvement.We know that resolution is defined <strong>by</strong> aperture but the ability to focus the different length waves closer to thesame point gives a more natural view. The white is whiter and the black is not purple.The typical halo around bright stars and the moon is gone or is almost eliminated. It is a big improvement.I still need to do more imaging testing. The weather has not cooperated to much, however I did some terrestrialphoto comparison. For the first test I used a small metal piece. It is a chromed object with a sphere on the top.
The telescope is about 40 ft from the object. This is not a perfect test but the sun reflections will simulate stars.Visually there was a difference. More light was spread over the area where the sun light was reflected. In animage the typical purple appears on those areas.
