After spending some time using the CFF 200 f6.5 for visual (and bino viewing) as well as some Mars imaging (still need to work on my planet imaging skills.  I turned my attention to the real use of the CFF 200 - DSO imaging.  I had to send my FIngerLakes PL11002 (full frame CCD camera) in for service.  Took a little time and the FLI service was great - PL11002 is like new (cooling down to -35C).  I took some test images of M33 using the FLI11002 and the CFF supplied FF (getting the spacing took a little effort, but dialed in pretty good).  I have included below the test image of M33 (no cropping) - a single 5 min sub using luminance filter (2")... image was stretched to bring out detail:

PixInsight of same image using Aberration InSpector:

I am pretty pleased so far - the full frame image is close to what I am looking for - will send LRGB version (6 hours of data) after processing

Hi Drprovi57! I am not an imager just visual(SW100ed). That is one tremendous photo! For 5! minutes!! Super WOW! I for one would love to see one with six hours data. Always wondered WHY one would purchase such a behemoth? Understanding is beginning to crystalize.

Many clear skies and good seeing

Beautiful! I have yet to fully utilize the imaging capabilities of my 185. But I moved very recently and the planets will be gone soon (unfortunately!), giving me time and space to image :)

 

Do I see some tilt in the upper two rows of images?

yes - there is still a little tilt.  Requires very little adjustment - difficult to get just right... I will continue to tweak the tilt, but also want to do some DSO imaging while i have clear skies.  I do generally crop my images, so not sure its worth a lot more effort..even thou I enjoy the tweaking part of this hobby.

I was able to collect some additional LRGB data (about 4 hours) of M33.  Had some high clouds and still learning LRGB DSO processing with PixInsight.. but the CFF 200 looks very promising for some future DSO objects - now i just need some decent clear skies..  Image taken with FLI PL11002 CCD camera.

Fantastic image, and 4 hours is not that much integration time. Do you guide offaxis,onaxis, or guidecope? Also, did you place the camera at 90 mm from the FF + 1 mm for the filters?

Wow again Drprovi57!! This image is the first one where I can see faint diffraction haloes around FAINT stars!! Unfreak'n believable! Fantastic indeed! More please!
Everyone please blow up the image fully:Prepare to be awed!

CS & GS

Thank you for the many !!  lol.gif

 

the haloes are due to my RGB filters - I am looking at some new filters that will provide less halo.. but they do provide an interesting perspective to the images...

I used a 90mm f5.5 guide scope attached to the CFF 200 (mounted on top)

 

I did the place the camera at FF prescribed distance, for my FF it is 91.5mm + 1 mm for filters.  However, getting the exact spacing takes some tweaking of the spacing with a delta of 1mm.. hard to measure perfectly.  I still need to make some fine spacing adjustments - but I will wait until I get the new filters.
