Guiding Fine Tuning

[Rod Bell]

Last night we finally had a good night so I decided to print out the Baseline PHD2 instructions Brian set me, and followed them to a "T"...Including the New Equipment setup, and new dark frames.

I have excellent results too BTW. Went thru the list, started guiding and did not have a single issue all night. That has never happened in over my three years of doing this hobby...!

 It guiding down until it hit my roof line...(;>)   I was on the Iris Nebula.

My question on the balancing part of it is. When Biasing heaving East, how much is too much, slightly biased, medium, or aggressive..?  I don't want to overload the gears too much of have the scope wondering around on me. Should have marked the counter weight rod.

Thanks,

Rod

No takers on my question?

Hi Rod

Might not be any takers because this is more of a mount topic than a guiding topic

I don't think there's any hard and fast rule for how much weight is good for biasing. You want enough that the gears remain engaged but not so much that it imbalances the mount. With my counterweights, usually shifting the end weight by 1-2 inches is enough.

If you aren't doing the string-weight-thing that some use for your mount, you can try adding a small weight when you eastern bias it, and then when you flip your side of pier, you just remove that small weight

You might also try posting to the Losmandy user forum as well for more feedback

I’m probably okay since I didn’t notice it creeping while I was imaging. Started look good. What I’m doing is getting it perfectly balanced, then doing the East heavy thing. I’ll see how it goes tonight. If it does good like last time, I know I’m doing something right….     Thanks Brian

results are what counts, and what you describe sounds fine to me

Hey Brian,

Did the baseline set up again tonight....Running great without a glitch..running between 0.64-0.95", about an hour and a half now...!

Guess I finally got this thing figured out for the most part.
