Description

This is first light with my new Losmandy G11. If you're looking at one of these mounts and aren't too familiar or you're coming from a Skywatcher or similar like me you need to pay close attention to the way you shoot and read what the mount is saying.  They're extremely sensitive and they are seriously bullet proof. Solid. Mechanically simple.  I'm using it with the asiair pro and it doesn't communicate very well. You have to watch it. Meridian flips will work but you need to set the limits manually in the Gemini controller. There are a lot of small mechanical errors that need to be ironed out for it to be smooth. In this image I really couldn't get 600s subs without trailing while guiding. Even with decent RMS guiding results. (.8"-.4"). With this field of view the stars should be round. (don't look to close :-) I don't know why they're not. I wouldn't judge the optics from this image. I'll grow to love the mount and I can certainly see it's potential. Speaking of potential, this Apertura scope performs pretty well for a $600 doublet. I like the little flare off Sadr. These are all 10min subs with SII, OIII and Ha. I processed these in Pixinsight and sent over to PS for combination using Don Goldman's method. First time using that, still works good!  The D800 data I shot first and incorporated the narrowband data in PI to make a "master" channel. If the mount was working well at the time this would've been much sharper I believe.  

Living about 1800 light years away in the constellation Cygnus, the Sadr Region contains many dark nebulae in addition to emission diffuse nebulae. Sadr is a supergiant star of the spectral type F8 Iab, appearing yellow-white in color. It has a mass about 12 times that of the Sun and has expanded to a size of about 150 solar radii. With a surface temperature of 5,790 K, the star has a bolometric luminosity 33,023 times that of the Sun. Wear your sunscreen!!
