Lunar craters


 This is a trial for lunar high resolution imaging.  The technique is quite complicated and involves obtaining a video of the lunar surface with 5000 images.  This data file is always corrupted by the atmosphere, so only the best 10-15% are selected for processing.  This data is stacked and processed in several different astro programs to give the final image presented here.  I am happy with the initial trial of data collection and processing.  The next step for me is to obtain multiple sets of video and to combine them as a panorama.  This data collection will take some time as the moon needs to be high in the sky away from the surrounding trees.  Clear skies needed as well.

IC 410 Tadpole nebula

 


                                               IC 410   Tadpole nebula

 

 This image is IC 410, the Tadpole nebula.  The image was obtained using Narrowband filters with approximately 19 hours of data collection in a relatively light polluted region of northern Virginia.  The narrowband filters (Ha, OIII, SII) are effective in removing the light pollution.
