Dithering time wasted?

Yes I agree it's taking too long. 

So by your calculations my imaging camera is 1.18 arc/pixel

so 12 x 1.18 = 14.16

guide cam is 5.95 arc/pixel 

So 14.16 / 5.95 =2.3798

Last part you lost me where is the dither level? I found the scale but not the dither level. I'm using APT as well if that helps. 

Thanks for the help appreciated!

Ok so please can I check I have this right. 

If I want to move 20 pixels 

my calculations are like this 

20 pixels x 1.18 = 23.6 Dslr

Guide cam is 5.95 arc pixel

23.6 / 5.95 = 3.96

so to move 5 on the scale is enough? 

Here is how I have it set up  

I know it says 4 took the photo then realised after. I mean 5 

 

So if that is correct what do I need to do with the settings in APT? Do I not need them anymore? 

Thanks  

Gerry

Looks good to me. How is the backlash in the mount? DEC will normally overshoot and take the longest to settle. PHD2 next. Here's mine down in a turbulent Sagittarius. If we agree on this, can you post a guide log? HTH.

 

 

Here is mine. What do you think remember I have a miniguide cam. 

What version do you have of PHD2?

Thanks

Looks good to me. Do you have a log handy?
