11" SCT and STF-8300M CCD Camera, 1" Refractor Finderscope and ST-402ME CCD Camera

Description:

After the outburst on April 4 Comet C/2015 ER61 Panstarrs is now about magnitude 6. The comet was moving 1.3 degrees per day in our skies when these images were taken, thus the streaked stars in such short images. The only way to take images longer than a few minutes of comets moving this fast and not show star movement is to remove the comet from the streaked star field of the original image and insert the comet back into a static star field using photographic artistry. Makes for a nice picture but does not reflect reality.
