SH2-225 (Sharpless 225 ) This Sharpless object is somewhat on the fainter side over all. However, the brightest area does well with the standard wide field CCD color filters, even though the nebula is mainly red. A larger telescope would resolve this area nicely and I believe a good narrowband color image is possible although I have not tried it. Overall, the hydrogen-alpha filter does very well here to capture the fainter area of this object. For a complete list of the Sharpless Catalog visit my main site at http://www.sharplesscatalog.com
