Yep, have it set to Solar.

Do you have lunar, solar and sidereal rates on your mount controller?
A small or moderate amount of drift should make no difference in processing your solar data.

When you are capturing AVI's over a long period of time it still drifts a little. My mount is dead on, but there's still a little drift.

Hi Guys,
I don't know whether I'm missing something here but why do you have to "guide"? Surely all that's needed is good polar alignment and RA tracking. I've Polar aligned my Solar rig (102mm ED Apo for white light and an 80mm PST on an EQ5) by aligning at night and spraying around the tripod feet with white paint. This works a treat although I am monitoring my captures on my MacBook. I use the boot (trunk) of my car with a canopy made of black table cloth as a "imaging station". I suppose if you are not setting up at a regular place you can't do this but you must have something close to polar alignment some how. Yes I don't get what you mean really.

Finding a guide package that will guide on solar features has been a several
year hunt for me. There is an interesting discussion on my forum about just
that where a guy has designed and made ready for purchase a pinhole solar
guider. The problem is that there are no pinpoint light sources in the FOV
with solar and all the guiding software out there needs a star, not a
sunspot.
You're probably not doing anything wrong, just experiencing what all us
solar nerds have to endure....everything is still designed for sissy night
time astronomy..:)

Sorry guys, I'm playing the stupid card. I can usually figure this stuff
out, but I must be over complicating things.
It all works great except I cannot get this darn thing to guide. I've got
the GPUSB cable, and it manually corrects the mount just fine using the
software keypad. I'm using a CGEM mount and a Lunt 60 Ha Solar Scope with an
Imaging Source DMK 31 AF03 monochrome CCD camera. I've tried to follow the
instructions, but I seem to be missing something. (maybe PHD, and the SSAG
spoiled me) As of now, I'm having to do sight corrections using RDP and my
Ipad while doing other things inside. The Applescript works just fine, so
does the movie conversions, etc. Great work Milton...Brian was right. Now if
I can just get over this guiding learning curve, I can pretty much fully
automate my Solar imaging sessions.
Thanks in advance!
