The Vixen ED 100Sf now includes a Dual Speed Focuser. Vixen's apochromatic refractor has an extra-low dispersion (ED) lens which depresses residual aberration to achieve a high level of performance. Coupled with a medium f/9.0 focal ratio, the ED "S" series provides sharp, high contrast color-free images. For the astronomer that wants the best value for the dollar in a 4” APO, this is the one to get.
Dimensions: 100mm x 880mm/ 3.9 x 34.6 in. Weight: 3.7 kg/ 8 lbs
The ED100Sf comes complete with:
- ED 100Sf telescope OTA with dual speed focuser

- Tube Rings

It's pretty much the only choice.Pros:
Strong Construction,CompactCons: Comments:
This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.
It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.
