Re: Last night tracking with Mach2

Terri Zittritsch
 

Rolando, thank you for the update.   There's been a couple of times now where I just wanted to roll the scope out during the day to use it for solar viewing, but didn't because i didn't want to get the table, chairs, etc, etc..
Looking forward to helping you test.

OK, got it.  


BTW, did my first APPM mapping run last night and activated tracking rate correction for the first time with the Mach2.  (Third use of the mount under the stars. ) Got a series of 56 x 4 min. unguided narrowband exposures over 3.7 hours.  The modeling - 68 points or so - took a half an hour while it was getting dark, the sky was settling down and the optics were cooling down.  

It worked wonderfully.  Used all 56 frames in the integration stack.

I am very impressed with the mount and the software.

APPM works differently - it does not use bright stars, just star fields. You need dark skies for that to do plate solves. In my keypad routine you send the mount to known stars using a planetarium program. Completely different way of doing a model.

So can anyone do this with just a mount and APPM? Using a Ha filter 2 hrs before sunset at .03sec exposure and build a model????

I think what you're explaining is your new hand controller SW for the mach2, can you say when it might be available?    I'd like to be able to use the hand controller at some point, even if it doesn't have all of the fancy features enabled yet.   Right now, always teathered to my PC.  I don't want it before it's ready, but is there some outlook?

I also don't use the hard plastic cable guides any more either! I now have two of them that live in my spare parts bins.

Re: Last night tracking with Mach2

So the model is still valid after a meridian flip?
Each side has its own model. You make a model for one side, then you make a model for the other side. You do this before it gets dark. When you are actually imaging, the models will be applied according to which side you are on. If you never move the mount (i.e. permanent setup) then the model will be good essentially forever. I made a model a week ago, I used it every clear night after that and it worked the same every night.

Me too, I would like to be able to have it, even if with the PC it goes perfectly well, because once the model is done it rolls by itself.His arrival with my stowaway's 92TCC will make him happy.

And congratulations Rolando, because new demonstration that with this frame we can put guide glasses, optical dividers, guide cameras and other PHD2 in the closet, with or without keypad.

I am researching setting up automated meridian flips with Sequence Generator.

I have set up a one hour [15 degree] meridian delay in in APCC for point mapping and then for imaging past the meridian.

What I am wondering is whether the information concerning my APCC defined meridian delay is accessible to SGP and is is used by SGP in calculating the modified meridian position?

I can't find any information on this in the documentation.
Dean, I use SGPro and APCC very successfully with the Mach2.      I set my meridian limits using the editor and enable those limits.   After doing this, and picking a target that is within those meridian limits (early flip area - bring weight up or imaging past) it works with SGPro sequences.  IN fact you can test it prior to actually imaging, just pick a target in the early flip area to see that it starts weights up.    I've never had to change a thing in SGPro.   I do have the box checked on the meridian tab to send limits to SGPro.

I've tested it to the limits to where it goes to my target, in some cases almost 3 hours before a normal meridian flip.   Works great.

Re: Last night tracking with Mach2

So the model is still valid after a meridian flip?

APCC and APPM is amazing

Barry Megdal
 

Finally had a night with decent (not great – 2”) seeing, and this is part of a run with my 1.6 meter focal length very long refractor (AP206).  1600 mount with encoders.

 

Large APPM model I did back in February, which now works better with the latest APCC.

 

It wasn’t this perfect all night, but no guiding was needed at all during this interval:

Re: Going Unguided With a Long FL Scope?

Mike Dodd
 

You've accomplished a remarkable recovery. :)
Sorry about the stroke - good to see your still at it!
The interesting thing is, the scope arrived while I was in the rehab hospital, so one of the first things I did after coming home was to install it on the AP1200 with the help of my wife and daughter. It was a bit scary mounting a 130mm APO with only one good arm and hand!

I've recovered about 95% of my left-side functionality.

Thanks for the good wishes, fellas.

Re: APCC and APPM - just wow

 

your shot looks great! 

we have to get this setup dialed in to image in earnest

no diagonal in there. still hunting it down

I'm wondering why a lot of astrophotos are posted L-R reversed. Yours seems to be reversed. Is there a diagonal in your image train? That may explain the strange reflections.

wrapping up first light, I apologize for the rather terrible reflections and total lack of any calibration frames, but for 20 mins of lum integration (@ 60 sec/image) and the crazy polar misalignment (due to lack of tech ops time at the site) i have to once again say APPM is pretty magical for correcting this, and super easy as a first time user


now we just need to hunt down those reflections (any ideas anyone?)

Just for laughs I auto-ran APPM "small" model to see if I could correct that, hoping maybe we could pull a first light that had at least sort of round stars and not just a smear. Never used that part of the program before, but 20 minutes later, it successfully completed

i'm doing some quick images, but we have round stars, and the offset it's correcting is pretty egregious:

If people are using FITS Liberator to import photos into Photoshop for processing, it defaults to: mirror image (or some language to that effect) and you have to uncheck it most of the time (unless you know for sure your images are flipped). Maybe?

Re: Going Unguided With a Long FL Scope?

Tony Benjamin <tonybenjamin@...>
 

Hehe,

Yeah...I was wondering about a 130 mm guide scope :) Sorry about the stroke - good to see your still at it!

In the end I went and ordered an Optec TCF-Leo which should allow me to use an OAG with the C11 Edge - if I want too.

I'm impressed! Your guide scope is ten times the aperture of your
imaging scope! I'm sure you meant something different. :)
Awk! I can't type any more, and apparently I can't proofread either. The diminished typing ability is due to a 2007 stroke, so I usually proofread things three times to compensate. Missed big-time today!

My guide scope is 60mm aperture @ f/5, and the imaging scope is 130mm @ f/7.

Thanks for the heads-up.
