Exploring the Digitized Sky Survey

Exploring the Digitized Sky Survey

Cederblad 214 - is an emission nebula in Cepheus.

The effect of stretching an image of Ced 214, using the Digital
Development option in MaxIm DL, can be quite dramatic. This is one of
the reason why I am concerned when I read about new discoveries of
pieces of nebulosity which are usually no more than a small part of a
larger whole.

This annotated image shows how images can be matched up to items in
the standard catalogues and how sometimes it seems possible to find
objects that don't appear in the astronomical literature. For example
I don't recall seeing any mention of these pillars before or the dark
area marked with a ??.
