Thank's Dunmunro
I already have & use AA8. But i don't find sigma clipping.
Only sigma and sigma + sum

Re: Sigma clipping

That's fully implemented in AA8 - check out the AA8 demo.

Re: What are these?

They are present throughout the whole frame. Thinking that they might be Hot Pixels, I applied the hot pixel filter to each one of the 20 x 5mins subs before dark frame subtraction, aligning and stacking (Sum). I Suspect that they are hot pixels, which have been elongated during guiding, and thus b...

Re: Plate solving in AA8

Thanks dunmonro for the quick reply. Yes I have the astroar8.DAT in the AA8 directory. I save and load my platesolving parameters as you described and both the platesolve or immediate platesolve work well. However, the platesolve in the telescope control (center platesolve) never works for me in AA...

Re: Plate solving in AA8

@dunmunro, thanks for the comprehensive summary on the plate solving centering function in the "telescope" function. I searched for the "platesolv.dat" file you mention in the program folders of Astorart, but couldn't locate it. I was using it happily in AA7 with 80-95% success rate. In AA8 however...

Re: Feature request:AA6 focus algorithm with FF focus.

Hi, the "AA6 method" cannot be used on multiple stars at a time, but there is no need for it: the method "Small disc" is actually the same thing, even more precise. I suggest to compare in the focus window the "AA6 method" and "Small disc", they are very similar. Fabio. Thanks, I'll compare them to...

Feature request:AA6 focus algorithm with FF focus.

Feature request: AA6 focus algorithm with FF focus.

Would this be possible? I find the AA6 focus algorithm the most accurate, but it's not available for FF AutoFocus.

thanks

Re: Plate solving in AA8

I started out in astro imaging, when I retired in 2002. The first project was to build a roll-off-roof observatory, and after the first winter I added a warm room :) . The RoR obsy worked fine, unless it was very windy, which caused problems with the 12" SCT on a fork mount. So in 2008, I built an ...

Re: Plate solving in AA8

Thanks for your input guys, it is much appreciated. I will continue investigating AA8's Plate Solving function, indoors while this cloud persists. I don't want to be wasting imaging opportunities on it, while I have a very effective Sharpcap/All Sky Plate Solver combination to use. As I said earlie...

Re: Plate solving in AA8

Now that I have got AA8 'talking' remotely (Ethernet) to my setup, I thought it would nice to run everything, i.e. Capture, Guiding, and Plate Solving in a single package. I am currently using Sharpcap with PHD2 for capture/guiding, and AA8 for processing. As I am currently stuck under a blanket of...
