ED80 vs ED100 for astrophotography?
Hi all
Was wondering for astrophotography, what would be the adv/disadv of the ED80 vs ED100? My understanding currently is as follows:
- ED80 generally wider view then the ED100 (on average 600mm vs 900mm?), great for some views such as Orion Nebula whilst not enough reach for others such as Omega Centauri (not close enough).
- ED100 with it's 20mm greater aperature makes for more appealing observing scope than the ED80 (?% more light gathering power)
- ED100 not as portable as the ED80
Is that right so far? Your help would be greatly appreciated thanks.
