Lagoon Nebula

M8 (Lagoon Nebula)

First light image from my new Radian Raptor 61 refractor telescope. Not too bad for only one hour of integration time using the Hubble Palette for a really cool false color image. I’ll be adding more data to this as the summer goes along to see how more data improves the image quality.

And because I don’t want anything to be simple, I was also using a ZWO filter wheel, ZWO Off-axis guider and a new guide camera on my first go with this telescope.

I now understand why so many people like refractors, especially when I compare it to my RASA 8 telescope. Since the Raptor 61 is f/4.5 compared to f/2 on the RASA, it’s a bit more forgiving. Because the RASA is so “fast” anything that isn’t exactly right with your setup is apparent.

On a side note, the OAG appears to be auto-guiding much better than when I was using the separate ZWO guide scope. And since I have the Raptor 61 piggy-backed to my RASA, I’ll be using the Raptor to auto-guide for the RASA. Can’t wait to see what differences that makes with my RASA images.

I’ll also be adding a ZWO auto focus unit to this telescope as well. The unit I have on my RASA seems to be performing pretty well so far.

Update: Radian Raptor 61 piggy-backed to the RASA 8.
