ES 80mm apo question *DELETED*

This guy posts pics taken with an ES 80ED triplet, admittedly of DSOs rather than planets but it can resolve quite a bit of detail in a globular cluster.

for moon it's every good,but on jupiter it's not good,because it's too small ,the details too less!
Open cluster and double stars also every good on observed!
my english every poor,sorry!

Just have some expectation management. Your 8 inch will be better for most objects (including planets). But, these little scopes really can pack a punch. Plus, they have pretty quick cool down times. Not sure about triplets though...they may require a little extra cool down.
On the moon you could push the scope even more.
I feel a small grab and go is perfect complements to larger dobs. For a quick session, waiting for the dob to cool down, or traveling...
I have no experience with this particular scope though.

Yeah I don't like using ridiculously high mag on the planets unless the seeing is superd. On most nights I'm fine with anything between 125 and 150x with the dob. The lower power views seem to be a bit more pleasing
I use mine all the time with my ES 82° eyepieces. IMO they are a perfect match for this scope. I have never tried going beyond the 102X that the 4.7mm allows for. I am completely satisfied observing Jupiter at that magnification.

It seems to me the claim of 315x is way into the rediculous range; consider that 160x gives you only a .5mm exit pupil. 315x would be .25mm; that's terribly dim and I can't imagine it wouldn't be into the "empty magnification" range.
I use my N3-6 zoom for most of my lunar/planetary viewing and 160x is pushing the limits most of the time. Under exceptional conditions I have used my scope at ~240x with good results on Mars.
Between 120x-160x is sufficient to easily watch Jovian shadow transits and see the GRS if the seeing allows. I can switch to a 21E and get 23x and a 4.4° FOV so a little 80/480 can be a lot of fun as a compliment to larger scopes.
