Latest Spectra of bright star Phad in Plough

This is an easy one as it is an A0 spectral type.

Type Ao with SA200 grating

Horsehead Nebular – Last night 150 sec X 3 per colour

Interesting that a medium sized telescope can find objects orbiting stars 880LY away!

Yes, this is the result of a star measurement session. A time series of V filtered measurements of RW Tri at 880LY.
From this information you can estimate sizes of objects and rotational period.

It is 2017 and to start the New Year– Orion Nebular!

I just love this nebular.  Star forming area of dust and gas. This is a better image than before Xmas.
Two sets of exposures to get the core and the dust areas.

Techy bit:  3 x 100sec per RGB and 4 X 130sec L  merged with 3X 60sec per RGB and 4 X 60sec Luminance. Taken with 8inch RC astrograph with a Trius H694 camera running ar -12C. Filter system is StarlightXpress Mount is AzEq6 pro.

Cacoon Nebula 8 Sept 2016

Ok I have taken quite a good image of this tricky nebula.
Take a look on the web and look at some of the images.
4 X 400sec per RGB.  No darks. (had to manually take out a couple of hot ones)

Last night M51 -Bit windy so not quite round stars.

Not bad image considering the gusty wind.  Just 3 X 300sec per colour
