TeleVue AP102/877 telescope:
The TeleVue 102 is a classic apochromat doublet telescope made to the highest standards. With an aperture of 102mm and a focal length of 877mm, it is ideal for all astronomers who are looking for an apochromat that can be flexibly built onto.
Even at the highest magnifications (around 300X) this instrument produces an image with extremely low chromatic aberration, although there is also no field curvature correction (as compared to the more expensive NP101 for example).
When used with a 55mm Ploessl, for example, it shows a respectable 3° field of view of the sky, all at 16X magnification. Thanks to the long focal length, moderate eyepieces are sufficient to give maximum magnification for planetary observing.
The TV 102 also provides a good image when used for astrophotography: images at F8.6 are sharp, slight blurring at the edge of the field of view can be expected however, due to the image curvature. With the help of a focal reducer (at 6.88), as well as the use of a field flattener (0.8 L - see accessories) however, this effect can be compensated for.
The advantages in a nutshell:
- versatile, expandable apochromat
- suitable for astrophotography
- sharp, low chromatic aberration image
