Re Konus 114 - 500mm vs 900 mm - Pl help!Posted By Gamini Ekanayake |
Could an expert pl help?
I am new to the hobby & identified the Konus 114 -4.5 ' reflectors.
The choice is between the 500mm vs 900mm focal length versions- simply due to availabilty in my locality here in South Africa & of course the price.
I am not much interested in photography but crave to see deep sky objects .
My understanding is that for a given aperture, shorter focal length is the more suitable for deep sky viewing- ( I know 4.5" ( 114mm is not enough for deep sky)
To complicate matters I saw in website by a dealer of Konus that the 900mm is the more suitable for deep sky stuff.
Which one shd I choose? 500mm or 900mm Konus Reflector?
Help would be greatly appreciated
