Re: Guiding on my plate again - NEED TO IMPROVE
more info... I'm in a dome. (no wind typically). My mount it normally not moved. I check PA usually once a year. conditions seemed okay on the weather stations but when I went out and looked I saw fog... I did a long GUIDING OFF run - and then guiding assist. It sais PA was off a little, I went out and tweaked PA and did guiding assistant again. Said PA was nailed. No improvement. I'll try to attach the log. I don't mine it a little high, but when it's higher than my image scale and my stars are elongated over 300 sec exposures - It's frustrating. 80mm guide scope, Lodestar SX. XS? imaging with 620mm

Guiding on my plate again - NEED TO IMPROVE
Have you found multistar to be better? I tried it and didn't see any improvement. My guiding has been poor for months then GREAT for months then back to poor since I got the Mach1 My history - Mach1 came... - lousy guiding at about 1.2 - after months to trials - it just turned to great. YEAH like 0.23 -0.28 great for months. Then turned to crap again and It now fluctuates at .8 to 1.8 mostly hovering around 1.05I had other issues with the RASA to solve. I'm good now on it... so the final thing to tune... guiding again I do drive by shootings where I stop click one frame and move to the next. This one was of those last night. more often I have elongated stars = (
300 seconds - ASI094, RASA 11, Mach1 and NINA @ 100 gain. just stretched no calibration frames. I don't play that.

Re: Multi-star guiding
Brian ORourke
I believe with MaxIm you can select what stars are used by reducing the image field. If you drag your mouse to create a smaller field you can eliminate a problem source, ( a galaxy core perhaps), but you are still dealing with the whole of the new field. So a weak star with a poor s/n ratio would be included.

Sorry again – that of course should have said “listed on Astromart”, not Ebay.

Sorry for the previous blank email.
All this talk of 130EDF Field Flattener made me look in my AP accessories drawer, and I have one I no longer need. It is listed on EBay in the Refractor classifieds.

Re: Multi-star guiding

I tested out PHD2's new multi star guiding and it worked great. Seeing was decent and I was at a dark site though.

The only benefit that I see is during poor seeing when a single guide star is jumping around but an average of multiple stars seems to lead to a smoother guide graph. During good seeing I can't see any difference.

This looks interesting. When you do the multi-star guiding does MaxIm allow you to select which stars to guide on ? I am trying to get a grasp on what benefits can be gained by multi-star guiding. I don't think that you can compensate for field rotation with multi star guiding, but Terri's comment about averaging out the seeing makes sense. -- Roland Christen Astro-Physics

Re: Multi-star guiding
wow that's interesting! I hope you'll share the details of your setup and results either here or over at PHD Generally we (over at PHD forums) have seen the smaller the image scale, the less impact multi-star has, but i haven't yet heard anyone with the combo of long focal length/oag and poor seeing talk about their results and details

Re: Multi-star guiding
I just started experimenting with PHD2 new dev release which has multi star guiding. I can attest that in poor seeing there is noticeable improvement in guiding. This was with my EdgeHD 11 on AP1100 with OAG guiding.

Re: [ap-ug] Snapshots - Sugar Sprinkle Galaxy

Spectacular image. Really captures the essence of this object.
From: <main@ap-ug.groups.io> on behalf of "Roland Christen via groups.io" <chris1011@...>
Hello Astronuts,
Had a couple of clear nights with reasonable seeing and decided to shoot a couple of objects that are well placed right now. First one is M33, which resembles sugar sprinkles tossed on black velvet.
https://www.astrobin.com/full/bovv9h/0/?nc=Uncarollo
I've been working with the Mach2 mount now for almost 2 years and I cannot be more pleased with the way it has worked out as a premium product. It really is a fun mount to work with, starts right up every clear night, points quite accurately even without modeling, tracks beautifully down to the sub-arc second level with nary a burp or hiccup. I have done unguided and guided imaging, both of which are a snap. The Lodestar guider is essentially foolproof, very sensitive in the off-axis guider on the QSI camera. MaximDL6Pro has a few quirks that I haven't figured out yet, but as far as imaging and guiding, it is unbeatable.
Bottom line - I would rate the Mach2 as the perfect beginner mount for the simple reason that it will do exactly what you want and you won't have to mess around with it trying to hyper-tune it, or adjust it. Just point and shoot and it will carry you down that 6 lane Milky way like a turbo-charged Veyron Super Sport.
