Index files suitable for your telescope+CCD field of view (


Recommended Posts

I'm getting a little confused here.

Have got Astroberry up and running, loving it, but I would like to change from online solving to offline as online is taking around 10 minutes. Not a problem in the longer nights but last night...

So I need to download and install index files suitable for my telescope+CCD field of view. I'm having trouble working that out. I have a WO star 71 and an Atik 383.

Can anyone help and advise me what files I need to download from here please?

Thanks in advance

If you’re running KStars/Ekos/Indi just let the program tell you which files you need to download. In the Ekos control panel, go into the Align tab (bullseye) then click on the Edit Solver Options button (see screenshot 1). Now click on Index Files (screenshot 2) and you will see a set of tick boxes against a double list of files. Provided you have told Ekos the parameters of your scope and camera the file lists will indicate if they are essential for successful plate solving (screenshot 3). Sometimes when I try to solve, a message tells me that the next (missing) file was really necessary, but that turns out not to be the case in practice.F90747F0-98D2-43B6-91E8-B1D1714C19F0.jpeg.be18e41a00a1b5c45d9e33ee2fbff68d.jpeg

Thanks very much for your detailed reply. I did look at this but none of those options were green and I couldn't tick them.

I have inputted focal length and aperature (in at least one place IIRC) but maybe I have not put it in the right place (it does platesolve ok online) if you can tell me where I need to tell Ekos the parameters of my scope and camera I will make sure I get it done.

Appreciate your help with this.

The list options go green after you’ve downloaded the files to your RPi. Some more screenshots....

Firstly setting up your telescope information....

Next, you may need to do like I found, set up the astroberry folder as the source of the local astrometry files, then the colours may appear....

 Then.....

then when you select the appropriate astroberry folder - voilà!

In my case offline solver works very well and pretty quickly with the RPi4. Canon DSLR about 45seconds, guidescope and camera about 5 seconds and my new ASI533 around 11 seconds.

That worked great last night. Between the polar alignment and the plate solve I recon it must have been 10 - 12 minutes quicker in total.

Just got to sort the problem with the Lakeside focuser out, get the guide scope and camera delivered and sort out the cats cradle of cabling then and I am ready to image.
