This is a first light for one of my cameras after waiting on adapters.  This is a total of two hours of Ha using 20 minute subs. 

Camera, Apogee F16M,  attached to a TEC 140 on a Mach1GTO mount.  Guided with a ASI290 through a AT65EDQ since I don't have enough back focus to use a OAG.

I hope to get some longer time on this with additional OIII data.

Nice and SHARP!  20 minutes?  You must have excellent guiding.

Thanks.  I use a Mach1GTO mount which is a great mount. You start it and forget it.  Wish I had one years earlier.  My pier is four  6 by 6 treated lumber posts glued and screwed together, planted 3 feet into the sand. Very stable and no need to pour concrete.  

 

 

The posted image is no where as nice as the full image.  Jpeg compression hurts this image. 

 

Since this is only two hours, I will try to get twenty more hours in Ha and also OIII on this object and see how it develops.

Thanks.  I was using Baader 8nm Ha filter for this shot.  I like their filters with a minimum of reflections. In my other shot which I just posted you can see how little reflections there are with this brand of filter.
