Re: Help needed....(yes, again :> )


 


So, here are some questions for you:

What kind of scope again?
It's an Antares A520GP...Pythonese for an 8" Newtonian with Discovery
optics on a EQ-4 mount....

What makes you suspect there's any kind of problem?
Well, when I do a star test, I don't see anything resembling
a 'good'or even 'so-so' result....the airy disc looks like...er cow
poopoo....

Has it always been this way or is this recent?
It may have always been this way, and I just didn't know any
better....

What have you tried, so far?
I tried making sure the primary wasn't pinched in it's mirror cell (
looks ok, screws aren't digging into the mirror...)
I tried using the chesire tube and lasermax holographic collimator to
check if I was off( primary or secondary...)I seem to be bang on...
Yet when I do a star test, it doesn't look anywhere near what a good
star test should look like....

I know this is understood, but: yes, I let the mirror cool down each
time I tried the star test....and yes it was a cool down of more than
an hour...(actually 2.5 hours last time I tried...)

What kind of help do you think you need and to do what exactly?
Well personally, I have a fear of cubes....er I mean that I would
like another pair of eyes ( or 10)to look at the optics and
the 'seeing' with my scope and tell me if I'm out to lunch, or if the
optics/collimation/setup are waaaaaaaaaaaaay off.

Everywhere a Photon!
No worries....we'll eventually get together and I can take that 7.5
off your hands!

And thanks in advance for the help!
