How+to+determine+the+position+and+offset+of+the+host+Galaxy+and+Supernova

To determine the position of an object in an image, ensure that the image has been plate solved first.

If an image is plate solved, then click on 'Analyze' in the top tool bar and then 'Photometry'.



Two new windows will then appear. Ensure that the Information window has 'Mode' set to 'Astrometric', and that FITS scale 'check box' is checked.

Then, hover the mouse over the intended object in the image. The position (RA and DEC) will be displayed in the top half of the Information window. To verify that the plate solving (RA and DEC positions) are correct in the image, go to [].

Then enter the object/Galaxy required. When displayed, hover the mouse over the object. The position information (RA and DEC) of the object, along with it's magnitude etc, will be displayed. Compare the data against the data in the MaxImDL Information window.
