Telescope control window->Goto tab-> enter target name or coordinates -> click Goto button-> telescope slews to where it thinks the target is.ĮDIT: Now take an image with the imaging camera (IIRC ~30 seconds is typically sufficient). Now we are ready to use plate solve assisted GOTOs. You can also experiment with increasing the number of stars to 6 or more, again to reduce the probability of a false solve. Once known you can enter the correct info into the "find coordinates:" window and reduce the percentage to ~1-2% and then click "save parameters". Top of the AA7 main window-View-> statistics will give the plate scale and image centre make sure that this info is correct as false solves can occur when the Horizontal field parameters are too loosely set. Once you get a successful plate solve the RA/Dec will display at the bottom of the AA7 main window as you move the cursor over the image. You may have to experiment with some of the settings including the "image flipped" box. On the left hand side of the main AA7 window there are a series of icons including one called "find coordinates". Load one of these images and plate solve it: You should go through the preferences tabs carefully and enter your info as appropriate in the different tabs. You are now about to be initiated into the mysteries of plate solving.įabio should be able to send you a link to download the GSC (I can't recall where I got mine (I also downloaded the USNOA2 star catalog from the USNO)) but if you already have it you would go to:įile->preferences->star atlas tab->use the dialog box to set star atlas to the correct directory. Do I need to down load this atlas from another source? What is the best way with AA7 to get the initial alignment done? I redid my PA last night. I noticed that the Star Atlas does not open - I get an error saying: GSC not found. I was hoping to use the Star Atlas tool to help me align or plate solve. My initial alignment is off and my scope is way too up high to use the finder scope.
