Caldwell 48 NGC2775-hst-R814GB450.jpg

Caldwell 48 or NGC 2775 is a spiral galaxy with a central bulge and tight spiral arms. It was discovered by Herschel in 1783. Located some 55 million light years away it appears as a small face-on galaxy in the eyepiece but is actually inclined to forty degrees away making it oval. A challenging object to visualise.
