Alberto,
I have been looking at your DSO images today and have been very impressed. Those are possibly the best I've seen taken with a DMK camera and I did not realize that these cameras were actually capable of this type of image. Very nice, thanks.
I own a DMK 31AF03 and occasionally use it for lunar imaging but thought deep sky imaging was beyond it's capability. I also use a Starlight Xpress CCD and have tried my hand at some DSOs through a small aperture Mak, with limited success. The Starlight Xpress cameras with the Sony Exview chips are, in my opinion, a very capable cameras and can capture exquisite images in the right hands. You might find them useful sometime down the road.
My main point here is that I had the most fun imaging was when I was challenged by using a small telescope with a rather high f#. Because very few other people were using similar equipment I had the feeling of competition and strived to produce better images. Of course, larger scopes and expensive cameras could capture better images but that did not really matter to me. I'm hoping you will try to push the limits of the DMK camera for a while and enjoy your accomplishments. I know I will enjoy seeing your images.
Phil

THX Alan.
your words are alway very kind.
The day after i did a M13, M57 (both luma and chroma with The Imaging Source). Then i grabbed a M82 but i didn't process it yet.
Now it started to rain heavily. The Moon is incoming. I hope to be allowed to do some decent moon after 4 months of hungriness!
Two days ago a friend of mine lent me a CCD Starlight Xpress for a night.
Humm... i was pretty impressed by the very low noise allowing better DSO results even in urban skies.
For the moment i will continue with my DMK DBK (i'm affectionated and... with no money for a CCD!) but in my mind now there ia little bug eating my brain...
I 'd like to ask you a question: i saw a Thousand Oaks Halpa filter to apply to a normal scope (opening 80mm) that would fit perfectly on my 80ED.
The question is: would it be better a Coronado PST or the ThousandOaks filter?
Do you know them?

Thank you in advance

Hi Alberto -
These are some of the best deep sky images I've seen from a streaming camera.
best wishes,
