- A twist of the zoom eyepiece housing changes focal length from 21mm to 7mm; providing a variety of viewing magnification powers; excellent contrast and sharpness: making the zoom also of interest for planetary observing
- 16-33mm eye relief range allows eyeglass wearers to enjoy entire view; zoom eyepiece lets you change magnification power without physically changing eyepieces; apparent field of view is 30 degree at 21mm and 43 degree at 7mm
- Eyepiece consists of four elements with anti reflection coating for clear high contrast view; particularly large eye lens coupled with long eye relief means zoom provides particularly good viewing comfort; eyecup can folded down handy for spectacle wearer
- Really sharp planetary images are only possible using an IR/UV blocking filter; this Astromania filter only allows the visible light between 400 and 780nm through; the UV and IR regions of the spectrum are completely blocked
- Sharp Images: A CCD camera is not only sensitive to visible light but to other wavelengths; planets are out of focus in the IR region; the Astromania filters only lets through the visible light; meaning sharp planetary images
