Upgrade for my etx spotter
- Sheila B
The 2-4mm Nagler zoom will be an inappropriate choice due the excessive magnification (312x-625x) it produces in the ETX-90 with its 1250mm focal length. For daytime use, stay with something between 20x and 80x and you'll be much happier with image quality and your scope will be easier to operate as well. Even if you are trying to do astronomy with your ETX mounted on a standard camera tripod, I would not go much over 100-125x.
If you want to simply upgrade the 26mm eyepiece on your ETX, try the Meade Series 5000 26mm SuperPlossl. It will give you the same magnification (48x) as the older Series 4000, but it will also give you more eye relief and a wider field of view. The Televue Plossls are also excellent.
