Re: AP1100 coming, least hassle plate solver?

Hi Linwood,

Support for ASTAP and NINA in APPM have been finished. A few details need to be sorted out before it will be released, but it should not be much longer.

Subject: [ap-gto] AP1100 coming, least hassle plate solver?

I have an AP1100GTO-AE coming hopefully very soon. My understanding for modeling is I will need software to
build a model with APPM, and that I need some combination of Pinpoint, TSX, SGP plus camera control (though it
appears so long as I have ASCOM that's covered, it's a ASI6200MM I would be using). If it matters I got the
RAPAS, no keypad, and will be using it with setup and teardown nightly.

I have a MyT now I will be selling, so while I have TSX it will go with the mount.

I use NINA for session manager and hope/plan to keep doing so. My understanding is one day, maybe, APPM
will support ASTAP but not yet, and probably not before I need something.

What is the shortest and simplest path to satisfy APPM with the understanding I really do not care to use that path
for imaging. I.e. if I buy TXS, SGP or Pinpoint it will just be for APPM, and not for regular use during imaging. At
least that's my hope, that I can do that.

I could keep TSX for a while but it's not worth it, since I plan to sell the mount. With no release date announced for
ASTAP I think I need to plan on having to buy one of those three.

I realize I could get trials, experiment with all of them once I get the mount and see how they work, but my guess is
99% of their features are irrelevant if all I want is plate solving.

So I'm hoping you folks can save me some trouble -- what's the shortest, simplest path here. I think all of these
are in the few hundred dollar range, so in the scope of things it is not about cost, it is that I have so many other
things to learn getting started I just want the simplest solution.

Suggestions?

Need more info. Planewave  what size. Camera type? Single exposure? Length of exposure? Did you do a simple processing?

Stupid error on my part - A too-long cable connecting the Telescope-top computer to the female USB 3 connector on top of the Mach2 got caught and when it pulled out of the through-the-mount connector, it broke some of the internal parts. Is this gonna require I send part of the mount back for repair? Or can it be done in the field?

Hi Mike,

I use MaximDL for most of my processing.

Then in Photoshop I select this center part with heavy feathering and layer it on top of the normal stretched image. This works well for some galaxies too where the core is so bright that it saturates before the outer parts show up.

M5 has a very bright and "intense" core.
It does indeed and require quite a bit of advanced processing to prevent it from blowing out. I was also surprised by the number of faint blue stars around the outside.

Beautiful!

I am also quite interested in the 6200 and how it works with refractors in the 130mm range.  I have a William Optics Fluorostar 132mm refractor that is advertised as fully illuminating a full frame sensor (such as the 6200), but I have heard several reports of terrible corner stars and severe vignetting (the kind that flats cannot fix) when paired with this particular scope from WO.  Did you have any trouble fully illuminating the full frame of the 6200?

Less than a year ago.

Ray answered my question on the PEMPro support forum about reading the curve from the mount, so I know what that looks like (5.45 arcsec peak-to-peak). Tonight I'll run another curve with PEM enabled to see what the corrected tracking error is.

Do you recall when you last created your PEM curve?  The curve should be redone every so often (I do my 1100 annually).

The PEM curves are in Documents/CCDware/PEMProVx, where x is the version of PEMPro that you have, 2 or 3 most likely.

Re: Flexure Measurement - How Much is Too Much ?

Roland Christen
 

APCC itself does not have any impact on tracking.
APCC Pro has modeling which can be used to supply a custom tracking rate to the mount. That is another kettle of fish which itself will not change the characteristics of the mount's tracking behavior. It simply adjusts the tracking rate to compensate for various things such as atmospheric refraction, polar misalignment, instrument flex, etc.

I have PemPRO, and used it to create a PEM curve, which is enabled all
the time. At the moment, I can't find the curve, but I did create and
apply a curve.

Assuming PEM is enabled, would APCC improve tracking on my 1200 beyond
what I have now?

Thanks, Roland.
