Quote:Quote:One other question, my camera is not listed. Its a Mallincam. Does the software support that camera? Thanks.Jim 3rd party software generally doesn't directly support a video Mallincam because the camera's output doesn't directly connect to a PC. You have a USB frame grabber in between. So in most software a video Mallincam is setup as a webcam. The control side is different, there are a number of apps that can control a video Mallincam through it's unique serial control interface ... but the video still goes through the USB frame grabber.

Now you tell me. Last night I gave up trying to use AstroTortilla because it would not solve anything. Today, I used one of my images at let it solve and it took almost 20 minutes, which is useless for telescope work. I downloaded and installed this latest version and it solved the same image in 136 seconds. Now that is useful. I previously used Elbrus, which worked OK but I wanted something that was more automatic. I will have to give this new version a field trial, but it looks good so far.I would like a better explanation of all parameters, especially the scale parameters and their units. I first thought that it was arcsec/pixel, but the unit "degwidth" did not make sense for that. Regards,Charlie B
Quote:I've given up on AstroTortilla for now and have downloaded a trial for Sequence Generator Pro, which uses Elbrus and astrometry.net. I have been sucessful with Elbrus before. Last Saturday, I tried AstroTortilla but could not get it to open Nebulosity. It kept waiting on the camera, but the camera was working fine. I'm sure that it was my mistake, but I will wait for a more mature version.Regards,Charlie B

First thing to do is set "scale minimum" to 0 (zero) The setting you have, (25.???) is choking it which is most likely the reason it only solves a few images, not most if not all images...
If you know the image scale range of your telescope/camera combination, then it is better to set both a minimum and maximum scale. This will give AstroTortilla a specific range to search instead of a broad range. It will solve much faster with less searching. I've saved configurations for all of my different scope and camera combinations with reducers and barlows lens from 400mm to 5000mm focal length. With each configuration, I set a minimum and maximum in Arcminwidth and get a solve within 30 seconds at most.
2nd suggestion - Upgrade your software and index files to Version 5 and the indexes to the 4200 series. Get a new install from the Astrotortilla web page and run it omitting the CYGWIN (you already have this), and select Indexes from 4219 down to 10% of the FOV of the telescope/camera you are using...
I've found that I get better and quicker results with the 200 series indexes. I've done a side by side comparison with both the 200 and 4000 series and found that I get faster and more consistent results with the 200 series.
As you are using Arcminwidth instead of degreewidth for scale setting, I'm not sure what Scale Refinement of 0.1 is doing for you, normally Scale Refinement is defaulted to 0 (zer0) and left there.
The use of Arcminwidth instead of Degreewidth makes no difference in the calculation of scale setting. I prefere to leave the setting on "0" because I want AstroTortilla to use my image a full resolution without any additional scaling. Also, I prefer Arcminwidth over Degreewidth for calculating my image scale for long focal lentghs. At 2500mm focal length with my camera, I'd have to use decimal points instead of whole numbers. Remember, 1 degree is equal to 60 arcminutes.
Quote:I could use some help. I am using the older 200-series files as I was having very little success achieving plate solves with the newer 4000-series database files. Now the solving is pretty much hit or miss but at least I am able to solve some of them.
I totally agree with the success of the 200 vs. 4000 series. Now if you are solving from just one setup, you need to know your image scale and add a little buffer for the minimum and maximum scale. All of your images should solve in roughly the same amount of time. If some do not solve, that you need to adjust the sigma because of the noise level. I noise isn't an issue, then maybe you don't have enough distinguishable stars for the solving to work. I would suggest not doing a scree capture.
Here is a screenshot of my Astrotortilla settings. Every single solve has fallen within 25-31 arcmin range so I now just have the program search within those parameters. I take a 30 second or 60 second exposure with automatic dark subtraction, take a screenshot of the exposure, and then upload the screenshot with Capture and Solve.
Question: Why are you loading screen captures to plate solve? AstroTortilla can solve your captured image directly. I'm not sure if the format matters but I know it handles FITS and JPG files for sure.
Quote:How much buffer should I give myself when setting the Scale Minimum and Scale Maximum ranges? For example, my imaging setup's FOV (per Astrotortilla) is 20.62(X)27.73 arcmins. What do you recommend I put as the Min and Max?
It looks like you're imaging close to 2500mm. I get 18.82' x 28.27' arcmins with my 10" LX200GPS and DSLR combination. Try my setting below. I typically go 5-10 above the maximum and below the minimum. As long as your setup doesn't change, the FOV should always remain roughly the same. I don't know how your screen captures affect the final size if you are cropping the image or adding extra border information. The scale is 100% accurate only with your actual image file from the camera.
Lastly, how do I turn off the Config setting which automatically determines the range search of the next plate solve I will do? It seems to store the range of the previous successful plate solve, and then automatically begins with this range for the next plate solve I try to do. I would like to turn this feature off so that I can just set a permanent range for it to search within (e.g. the FOV of my current imaging setup +/- some buffer).
You must be talking about the Default setting. You are able to load, modify and save new settings from the file menu. The default configuration file [astrotortilla.cfg] is located in your local user folder under Windows 7. It may be somewhere else with another operating system.
You can either overwrite this file or create a new file which you will have to load each time you what to solve at setting other than the default. I've created six different setting for my various setups.
Quote:I've just started evaluating AstroTortilla (AT) for my own use and also discovered that it wouldn't solve any of my existing images. After some experimentation, I discovered that AT won't solve images with stars down to mag 19 or greater. It wouldn't even soylve an image of M45!

That is not an error I have heard of or seen before.
First thing I have to ask, have you been able to get Astrotortilla to resolve any image? Is this a very first attempt?
Please explain/describe your set up starting with the computer and operating system you are using, the camera and OTA, and what series and range index files you have installed...
This is all information needed to understand what might be happening...
Quote:I uninstalled it and reinstalled it, but it crashed the computer while installing cygwin. So that wasn't setup correctly. Maybe I can manually install it?

Yes, Make sure you have enough disk space on the Laptop and you can use the Windows file manager to cut and past from a USB drive or possibly you can link the two computers with an Ethernet cable if they both have Ethernet ports... There is nothing special about the CYGWIN, it can be copied from the other machine as long as you put it in its own folder complete with sub directories on the Laptop C: drive... This is essential so AT can find it... As long as CGYWIN is a carbon copy of what is on the Desktop, it should work...

Quote:astrometry.net and astrotortilla use the same engine - astrometry's solve-field.elbrus is supposedly a royal pain in the butt to install and get working, so there's no free lunch...why don't you post some images so someone can help you with the parameters? i have been using astrometry.net's solver for years now with great success. astrotortilla really brings it to the next level with solve & sync.
