A very **UNFAIR** comparison of CCD to DSLR!

This is a very **UNFAIR** comparison of CCD to DSLR!  It's unfair because of the following.

Differences

1. Taken on different nights
2. Guiding methods - 50mm finder guiding on DSLR and OAG for CCD
3. Coma corrector on CCD, NOT used on DSLR
4. 2x2 binning on the CCD, native iso6400 on DSLR

Similarities

1. Same telescope, +Akule my custom 35.6cm f/4.5 Newt
2. Similar processing routine

Also of note, the image scales are quite different and were somewhat difficult to line up.  I got 'close enough' and stopped getting precise alignment.  I don't think this a valid or fair comparison but a nice contrast to both style of cameras.

Here's a three frame animation comparing.

1) RGB via the DSLR only

2) Lum via the CCD and no filters at all

3) A standard LRGB combination of the filterless CCD as lum and the one-shot color as RGB.

Here's the DSLR ONLY

Here's the filter-less CCD 'lum' shot only

Finally the LRGB combination

Perhaps it not even a comparison at all, but the lack of clear skies and poor planning had me running over the same objects within a week's span or so and having used different cameras got me hankering for a comparison even it wasn't like for like

Hope you enjoy and feel free to comment or critizice!!

A refreshed Little Dumbbell - M76

I had previously shot this target on the same telescope ( +Akule  ) last year but used a DSLR.

Here's my more recent effort with a CCD.

Astrobin has the full 1:1 resolution

Now for the somewhat unfair side by side CCD vs DSLR

The DSLR, a Canon 7D is on the left from last year.  The new SBIG STF-8300M is on the right.

What is really unfair is that the integration times are MUCH different.

Still to me, there is a HUGE difference and I wouldn't want to use a DSLR as my main camera for this type of work.

The most fun was that I was inside playing games while the image was taken using Sequence Generator Pro and monitored via teamviewer.  The clouds started to pass but the guiding held up so I kept going!
