Trapezium E, 80mm

Tonight with a 5mm Vixen Lanthanum eyepiece in my SW80ED I saw the E star of the Trapezium blink in and out!

NGC 2403 (January 2018)


This galaxy is only about 8 million light years away and appears in our constellation Camelopardalis.  NGC 2403 is bursting with star formation, flowing gas, and other activity.

This image is 38x9' with the SXVF-H9C through the 8" Newt and Baader MPCC.  I am still tweaking this scope, but I like this image.

NGC 2174 and HD 42088 (Jan. 2018)



NGC 2174 is a bright emission nebula surrounding HD42088, a mag 7.55, O-type star in northern Orion.  Most large emission nebulae have an O-type star near their centers.  The orange star at lower left is HD252208, a type K star.  The brighter star at the top is also a type K.

This is a full spectrum image tempered by the Astronomik CLS light pollution filter.  The camera was the SXVF-H9C.  The image is a stack of 18x9' frames.

The telescope for this image is new, an 8" Newtonian reflector with parts gathered from various suppliers.  I am not finished tweaking the telescope yet, but I like this image.  I also like the speed of this scope.  Whereas my classical Cassegrain images (with reducer) at f/8.1, this scope images (with coma corrector) at f/4.9.
