Plate Soving
« on: 19:55:13, 13 March, 2017 »
Using SGP and pinpoint for plate solving it has come apparent that plate solving always fails & continues with blind solve to complete.   this is ok when at home as I have the internet,  But not if I have no internet like Kelling.


Any reason that pinpoint keeps failing ?

With Pinpoint, if any of the FL/Camera Pixel size/RA & DEC coords are not accurate, then a fast pinpoint solve will fail...

I have found in the past that the XPixsz YPixsz,  Binning, OBJCTRA, OBJCTDEC & DATE-OBS are the defining FITS header params.... it uses these to do it's "stab" in the right direction...

Check that the correct values are being written to the FITS header....

Have you tried PlateSolve2. It does seem a little more forgiving than Pinpoint, its also a bit faster.

Hi Chris...

I haven't come across this 1... is it free?

(Pinpoint have been boasting that they are the fastest solver around.... does PlateSolve2 really go faster?)

http://planewave.com/downloads/software/ and yes its free and Planewave supply catalogs for it to. PlateSolve2 is now an option in SGP. In my tests I found it more reliable

If all the supplied parameters are spot on and the RA and Dec in the .fits header are close then Pinpoint is pretty quick (though nowhere near SkyX with its search optimised custom catalog) but PlateSolve2 is quicker if the supplied data is less than ideal i.e. in the real world when doing precision slews where the image being solved may be a way off the Ra and Dec supplied by the mount.

You are not on your own Roger.

With my equipment. Using Elbrus and then PS2. I have never found PS, as easy as folks make out.
One theory that I have. I think to do a successful PS to target, you need a sky that is quite dark, with plenty of stars visible. I think. PS software, doesn't like light pollution.

Rog - SGP failover plate solving is Astrometry.net. You can install a local Astrometry.net server on your computer that avoids the need for a internet connection. You do need to make sure you download the appropriate search file to your fields of view and they are quite large. http://astrometry.net/use.html.

Paul - That is a little surprising as I find I can get images to plate solve way before it gets dark enough to image and when only something like Acturus or Venus is visible in the sky. If you go into the PlateSolve2 settings there are a whole host of parameters to fine tune star detection. You can try it in daytime on an existing image.

Cheers,   I'll have a look into PS2 upon my return from my trip.

I've done all that Chris.
It will plate solve a stored ccd image. But. If I select a patch of sky, with few stars. It struggles.

What exposure times and filters are you using.

"Normally" about 5-7 seconds with an L filter but if I want to get on target before dark, 10 seconds with an Ha filter.
