Re: Spikes!

 

PHD recommended min limit for image scale is 0.5" so i would?bin 2 at a minimum

all of your calibrations are problematic?

here's a typical example

the calibration run should be 25 pix across 12 steps, which is shown in the outside circle of the target here:


you can see you have only one step in the circle

if i zoom way out i can see the rest of your calibration, which looks okay, but the step size is way too big


So i don't know what your settings are, but i recommend you bin 2 the guiding and start with a fresh equipment profile

this doesn't directly address your question, but i think having a solid foundation is an important first step here

Yes, using my 178 it should be 0.35 when using the 178. I have binned it in the past but found that it didn't seem to help, so I just leave it native.?
Using my 1600 it should be 0.55 according to , it should be 0.55 because of the 0.7 reducer.

I put in a focal length of 1471 in the PHD2 wizard. Which is not exactly the spec for the scope with the 0.7 reducer (1422). I did this because the solver complained that my calculated focal length was actually?1471, not?1422, so the image scale is slightly different than what astronomy.tools reports.??

I think that I calibrated a few times as I was trying things out, so there should be several in there.
