Astrotortilla vs SGP

Post by Craig » Mon Sep 18, 2017 8:02 am

Hey guys, Astrotortilla is frustrating me to no end. Is SGP platesolving easier to set up and use than Astrotorilla ? Or should i save my money and continue trying to figure out Astrotortilla ?

Thanks
Craig

Wow! I'm not the only one! Thanks Craig, I thought I was the only one having a difficult time with AT. Unfortunately I can't use SGP with my camera, otherwise, I would use SGP.

I finally was able to plate solve an image in AT...that took me all weekend to figure out how to do that.

If you find a secret that works for your AT setup please let me know. Other people seem to have no problems using AT, but, I still haven't figured it out. GOOD LUCK!

Astrotortilla works great when you get your numbers setup correctly......usually. Now that i have switched to SGP, i would never look back. It is so much quicker and a lot more accurate it seems. However that being said, you do need to get your numbers in the setup correct for this to work as well.

Maybe I'll download SGP and try it out with the free 45 day trial. Anyone have a good link to a set up procedure for platesolving w/SGP ?

Thanks

I'm happy to help. It's pretty straight forward.

In a nutshell

Go to planewaves site and download the APM and UCAC3 Catalogs. They are the 5th ones down, you will see them.

http://planewave.com/downloads/software/

If you are running SGP do not download Plate Solve II because it is included in SGP just load the catalogs.

One of the files is just a catalog and loads. The other is a Zip file with its catalog that you have to open and save.

Put both file folders in a new file somewhere where you can get to them later.

Now go into SGP Equipment Profile and click on Plate Solve Tab and select Plate Solve II as your solver and choose Max Regions in the box below.

Click on Settings next to Plate Solve II and it will bring up a box. Click on File and go to the drop down to "Configure Catalog Directories"

Now just click the button to the right and go find that folder where you put the directories in and choose the appropriate file "APM or UCAC3"

Done

Now go to your camera tab in "Equipment Profile" and put your Pixel Scale, Read Out Noise, and Resolution Scale in those boxes.

Thats it your done.


I have mine set to use the LUM filter for 2 seconds when plate solving. I also have it set to 50 pixels as a minimum correction point. I have it set for 4 iterations so it can keep getting it closer until it gets its 50 or less pixels. I usually hit it when I first run it on the 3rd try. After a few plate solves (because it sets a sync point for each on in EQMOD) I can usually hit it in the 1st or 2nd.

I had it set for 2 originally and got a lot of failures because my mount does not do such a good job of getting on target the first couple of times. After I set it to 4 it never failed again.

I'm around so if you have any questions let me know.

I was able to get APM downloaded and SGP knows where it is. The UCAC3 zip file i downloaded. then when i open it it stays in download, im unable to show SGP where it is on my computer. Any idea where i steered wrong ? Also I'll be using a DSLR if that makes a difference.

Thanks

Whoo Hoo, SGP found it. Is there any way to test the platesolve now ? I'm under heavy clouds atm.

Thanks again

On the zip file just open it up and then drag it to your folder

what would the read out noise be for a Nikon D5200 ?

I'm not sure what camera are you using and then we can look up the sensor and get the information there

That's a Toshiba 5105 sensor in that camera. It has a 3.9 pixel size. It's a 24 mp cmos sensor and I believe the resolution is 6000x4000

I'll look for the other specs.

Yall are going to love that feature. It handles everything. It even creates all your targets for your mosaic.

I want to do a full 4 shot mosaic with the gt81at its 382mm. With my reducer. Could cover a lot of sky.
