Re: Guiding on my plate again - NEED TO IMPROVE

Ron Kramer
 

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

Ron Kramer
 

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
I've solved my other issues and guiding is back on my plate. 

My guiding went from .79 to 1.8 during the night. .  = (    I just can get it to settle down.  DEC goes WILD for seemingly no reason.  I went out and redid PA... and really got it close but no help.

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

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.

I don't choose the stars when doing multi-star guiding. maxim looks at the entire frame and guides on all the bright stars in the frame. Other than that, I really don't know what their criteria are for which stars to guide on.

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.

Hi Roland

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.

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: Multiple APCC Installations #APCC

Ray Gralak
 

Hi Marty,

Question: is this going to cause a problem? Can I install one copy on each computer? Will I need to register a different
email address, or can the same email address have multiple licenses.
Having more than one license with the same email address will not be a problem. Each license is unique, so if you wish, you can use the same email address for both.

[Edited Message Follows]

A quick question...

I operate an 1100GTO and years ago purchased APCC Pro, though I currently do not have it installed. I may very well
decide to install it in the future for that mount on a new computer dedicated to that mount. That new computer never
had APCC installed.

My Mach2GTO will (hopefully) arrive in a week or two and will come with another APCC Pro license. I plan to install it
on the existing computer that I will now use dedicated to this new mount. The existing computer previously had a copy
of APCC Pro on it but doesn't now.

So I have purchased two copies of APCC Pro and have two computers each dedicated to a mount. I have the same
email address registered in each case.

Question: is this going to cause a problem? Can I install one copy on each computer? Will I need to register a different
email address, or can the same email address have multiple licenses.



Thanks.

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.
