EPs and Barlow

My two new EPs and 2x Barlow have arrived.

The EPs have a AFOV of 60 degrees and are made by Meade (part of the Meade Series 5000).

I'm yet to try it all out due to rain, rain and more scheduled rain................




To calculate the magnifications: Focal length of scope / EP mm. For example, the 12mm EP yields a magnification of  900mm/12mm = 75x.

So, with my existing and new EPs and Barlow the following mags are possible:

  • 28mm = 32x / 64x
  • 12mm = 75x / 150x
  • 9mm = 100x / 200x

It's arrived.....

New SkyWatcher scope has arrived. Additional eyepieces now on order to increase magnification (highest useable magnification is 236x).

Eyepieces - 9mm and 12mm with 2x barlow (on order). Existing EP is a 28mm so only a magnification of 32x. The barlow and EPs will allow the magnifications of 32x, 64x, 75x, 100x, 150x and 200x.
