Hi,

I agree - unlike with the sun, which must never be observed without protection, observing the moon through binoculars or telescopes will not damage your eyesight - it may be uncomfortable though...

Hi,

165 quid is a good price for a new Mk4. I hope that you're lucky with customs!

from my experience the view through an astro ED80 is comparable to a good example of ED or fluorite spotting scope. With the Baader zoom you will get 25-75x.
As with most 3x zoom EPs, the...

Hi,

your ED80 is probably good for at least 160x (rule of thumb is 2x aperture in mm or 50x aperture in inches) - of course limited by seeing and available light during the day. Planetary observers...

Hi,

if you meant me - I do have a Skywatcher ED 120/900 with an FPL53 doublet - but the same Synta objectives are available from quite a few other brands - namely Celestron.
