you have me getting the HyperStar itch. Those are beautiful. I wondered what you would get with more subs. A whole 22 and 36 minutes, only 400ISO.... and what images! I wish I could afford a C14, and the CGEM DX to go with it.

Thank you Mo :) Funny thing is that 10 years when I bought the C14, it was only for lunar and planetary imaging. Thanks to the Hyperstar, I can do some DSO now :D The smallest SCT on which you can put an Hyperstar with a DSLR is the C9.25, it can be found for pretty good price at the moment ;) A moded 100D would be great too, hehe ( little size ).

Thank you everyone :)

@ Wes : no it isn't, that's why I do that much dark frames ( 30 ) to be sure to get rid of the noise. Furthermore, doing a lot of light frames reduces the noise drastically too. But soon I'll receive a CCD camera which can be cooled at Ambiant -40°C ;)

the 14in would be awesome for planetary, then a good fov with the hyperstar (as you know). The dual use makes it tempting. If I am ever able to get one, I'd just go for the C15 and CGEM dx package. Then I'd have 2 mounts. I'm looking forward to seeing your results with the CCD.

Very nice work.Good amount of detail for such short subs.

Tracking but not guided?

You might prefer the C11, the C14 is really big and needs a bigger mount. Maybe the EQ8 will be great for it, time will tell :)

Thank you Baz :) And yes, tracking ( adaptive king rate with a 6 stars modeling on the Gemini I, 3 on each side of the Meridian ) but no guiding. I tried 2 minutes, tracking was good, but the images were too bright and stars were burned out. The mount is a Losmandy titan by the way, pretty good with some tweakings :)

Haha, thank you Ron, but I don't think I have enough material to do that just yet ;) Maybe one day, after my job's retirement, who knows ;)

Here is another version, with smaller stars and different processing.

have you tried any narrow band imaging. I'm interested what ths HS would pull in with a Ha or OIII filter. And how quickly....
