The crowd is awaiting the next image Mike
Yes well guided subs with imperfect PA would be affected by field rotation but if the PA is close I don't think you would notice it once all subs are aligned and combined
Unless the PA was waaay off.

Ok ok soon

Went out last night to tweak away with the collimation of the AG12...aaaand in the dark managed to make it worse ....so getting late and being a work night, I though aaaaah stuff it, I WANNA IMAGE! and switched to the trusty FSQ106EDX4-FLI combo. Man, this rig just works ! great responsive goto after park and silky responsive centering, dithering and autoguiding (as good as or better than the NJP) . The extra size, speed, responsiveness and beefyness of the AP1600 over the NJP was palpable The below flatline guide graph looked like this all night.

New image soon

How boring, everything is working well and quality data flows in...just kidding - great that you are well and truly back in the saddle and again rescuing ancient messengers from distant worlds by letting them safely land on your camera's CCD.

Sorry, just had to share ....tonight the AP1600GTO is guiding consistently with average guide errors as low as +/- 0.18 arc sec ...as a person who cut their astrophotography teeth doing back breaking, blinding, eye ball watering guiding, staring through a guide scope...this is just amazing!

Back to it

Mike

That's awesome Mike great to hear a lot to be said for plain precision engineering ��

I was not expecting I would be able to say this... but.. I think the AP1600GTO guides even better than the NJP mount and that is amazing, not totally surprising but happy it's the case

It has been stuck on ave errors of +/- 0.04pix (+/- 0.2 arc sec) for the last 2 hours....

Noice..it’s a glee moment, when you finally twig that the effort you put into something is delivering as hoped. Currently bouncing up and down on my obsy chair having nailed Collimation..back to it 😉

Superb Mike.

Now the mount and tracking fall into the background unnoticed and reliable and you can concentrate on imaging without finding trash data the next day.

Indeed Greg Although I enjoyed that state of affairs already, with the NJP of course, most multi night image runs had no bad subs It is just nice to see that I have a nice surprise in a further improvment in guiding quality that was already fantastic, Im very happy

Now to keep imaging, last night was a perfect run

Mike
attached is the best guide star centroid plot I have ever seen, it was like this most of the night, that's 0.2 arc sec average errors over the whole night, no PEC and just PA via the AP right angle polar scope

With such guiding there is little or no reason to ever wish for encoders 👍

What guiding software are you using Mike?

Hi Sous vide 😁 I use Astroart5 on the observatory computer to control cameras, filterwheels and guiding.

Looks like you’re guiding on a hot pixel there Mike

That’s funny - but I prefer fast cooking on a hot bbq

Will check Astroart - thank you

There is an Astroart7 now but I haven't tried it, Astroart5 does everything I need at the observatory so I haven't bothered to upgrade but I do use Astroart6 at home for processing.
