Description

Here is a relatively short integration of the Rosette Nebula in Ha using the William Optics RedCat 51. The 'Cat tracked the night sky riding on an iOptron SkyGuider Pro, without the use of autoguiding. Dithering would have really helped, but it was just nice to get out and shoot again after a long hiatus.

Very impressed with the RedCat thus far. Extremely wide and sharp images when used with a crop-sensor DSLR like my old Canon EOS Rebel T3i. More info: https://astrobackyard.com/william-optics-redcat-51/
