The Lagoon Nebula in Sagittarius
 with the 10" f/3.9 Astrograph
Uploaded 7/4/16

This image reveals the suitability of the new 10 inch astrograph for emission nebula. The fast speed, allowed for full size unbinned color data so to exactly match the Luminance data without comprimise. Good star images are seen as well in the corners, that Baader MPCC works very well at this focal ratio. What works for comets works great for nebula too!
