Apograde review by Ignacio Rodriguez - William Optics

I decided to perform a simple star test defocusing the view (inside an outside focus) to compare the color leveland the diffraction rings. I used a Meade LPI and a Barlow to capture the images. The power was in the 160X –180X range. There was more color in the SD lens. That was very evident. The FD rings were similar inside anoutside focus although they were more difficult to observe outside of focus. The images do not representexactly what you see at the eyepiece. It is better to use a digital camera. I tried to obtain some images placingthe camera lens at the eyepiece. The detail is better than what I obtain using the Meade LPI however aligningthe lens to a short focal length eyepiece is difficult. It is better to use the telescope as the camera lens as I dowith film photography but I have not moved to DSLR yet. My digital camera does not have removablelens.FD star testSD star test
