[C14] What eyepiece to fill in the gap?
|
Jim,
I don't know when you will ever get to use a power that a 6mm or lower EP will produce. ?The 3910 focal length of the C14 would mean that a 6 mm would produce 650x, a 5 mm 782x power. ?You would have to have extraordinarily good conditions to allow you to go that high without serious image degradation. ?I hardly ever get above my 9 mm Nagler at 434x even on above average nights. ?That is just my experience.

Perhaps an 18 mm Radian. Gives wonderful views at about 250x.

¿ªÔÆÌåÓýPaul,

I took
the beast out tonight to a some what semi dark site called the Forks of the
Credit River (just north of Toronto) as the weather man/women is calling for
rain for the rest of the week.? The moon washed everything out (I think
they call it a Hunters moon).? Could not?get even M51, 63, 81, 101
into view.? M31 was the only item you could see.? Tried the Pentax
5.2mm?on it and was able to resolve down to individual stars but they were
fading in and out?- not stable at all.? Moon looked fantastic with the
5.2 and fit perfectly in the Pentax 40.? Jupiter was to bright to resolve
much of the bands.? Split some doubles and waited for Andromeda, but
she?hadn't cleared the trees yet when we shut her down at 1:30am. (have to
work in the morning)? The 28mm worked well on everything else but all in
all the seeing was very bad even for a clear sky.? Temperature only dropped
down to 7'C with a breeze of about 10-15klm.? Some shaking with the higher
powers.?
?
Hope
others will have a better week and look forward to hearing everyones
exploits.?
?
Clear
skies to all.
