ASTRO: M27

I imaged M27 to test my new AstroPhysics focal reducer. There were more than
15cm space between the reducer and the camera, so it was far beyond normal
use, because I had to fit the OAG in. I meanwhile have found that the
reducer fits into my Lumicon Easy Guider, which gives a much better
distance.
I combined a 13x10 minute colour image with the QHY8 camera plus Astronomik
UHC filter with last year's Halpha picture for the attached image.

Both imaged with a 10" Meade ACF on G11 mount from my Berlin inner-city
rooftop terrace.

Very Nice image Stephan.

What focal length was this at?

It looks like around 2 meters?

begin 666 M27-13x10+M27Ha104gut.jpg

that came out really well Stefan

looks like the spacing worked out anyway

Thanks Milton.
Your guess is spot on, focal length was about 1950mm.

Thanks Richard.
I had to crop the image to hide the bad stars near the edge.
I always admire your AP155 that produces good stars even for the giant chip
of the 39 megapixel camera.

I feel very lucky to have two nice AP refractors (155 f/7 and 180 f/9) with
field flatteners that work so well with those huge chips.

they sure make my work a lot easier.... they just work well.

I feel your pain because I used to use a Meade 10" LX200 and then a
Celestron C14.
