Re Konus 114 - 500mm vs 900 mm - Pl help!

Posted By Ivan Gastaldo
Hello Gamini,

The longer the Focal Length the smaller the FOV.
Normally for DSO's you'll want shorter Focal Length. The Longer one would be best suited for planetary views.

I personally think they have a "typo" by saying that the Longer F/L one would be the best for DSO's.



Clear skies, and good luck!

Greg, did you get your new scope yet?
If you did, how is it? tested it yet? did you, did you?

As far as LPI goes, hmmm, haven't heard much from anybody yet about it, maybe too new, maybe not out yet? anybody?


Clear skies!

Blistering paint inside sonatube

Posted By Ivan Gastaldo
John, is it happening just on the nearest area to the front of the tube, or across the whole length of it?

Could it be that it is being affected by dew & humidity, since it is the closest section the the outside of the tube?
How about covering that whole front affected area with something like ProtoStar Self-Adhesive Flocking Paper to hold it in place, and make it more resistant? (just an idea)(not to mention that it could improve your contrast too?)
