I just finished observing Jupiter and Saturn.
The telescope used was my Intes-Micro MN56 5"
MakNewt. I kept the telescope outside for 2 hours
before using. Jupiter was definitely improved
using the apodising screen. Saturn was a different
story. The loss of light prevented any real improvement. Using an 8mm Radian with a 5X poermate (475X) and a green filter Jupiter showed
a wealth of detail and the apodising screen
improved upon that consideribly. Cassini's division was a literal black belt, but the apodising screen made no improvement on Saturn
rings or the cloud belts.
My apodising screen consists of the following:
palstic bug screen from Home Depot
Outer screen I.D. 90%
Middele screen I.D. 78%
Inner screen I.D. 55%
rings rotated against each other by 30 deg.
all screens lightly painted with epoxy flat black
spray paint and then mounted on an aluminum ring
with tabs to slip over my telescope's front. I
waiting for Mars for the ultimate test.
For any clarification I can be reached at
425 222 3228 ex 124.
