NOTE: This thread is about the 2 different versions of the original Revolution Imager in the grey case, not the newer R2 model in the black case.
________________________________
When Mike from Revolution Imager announced that his new version gives better results and has better colour, I got pretty excited.
So when I received the new version of the Revolution Imager LN-300 with the better sensor I thought I better do a proper comparison before I make a Video about the difference in the OSD Menus of the two different models, so I could make sure there was actually an improvement, not just simply a different menu.
The old Revolution Imager that I have already posted video from is the LN-300 11673 1/3" PAL
The new Revolution Imager that I am doing the comparison with is the LN-300 11811 1/3" PAL
Firstly, it only took me about 5 minutes to learn the new Menu (video tutorial to come).
I did notice straight away that the new model has black banding across the top half of the video frame. It is ugly but it doesn't bother me too much. For such a cheap mass produced camera I expect a few manufacturing faults. No-one else has mentioned this so it must be just my camera.
The Biggest difference I did noticed is that with the 11673 (old version) the camera gives a reasonably good result of medium to bright DSO's using Zero AGC, wheras the new version 11811 did not show the same result. With AGC off the DSO's were barely visible.
But this is not really the bad news I thought at first. By simply setting AGC to LOW the same DSO's popped out in amazing detail!
When I tried using AGC in the old model it introduced a fair bit of noise, but with this new model, with AGC at LOW noise was well under control. A very pleasant surprise.
The comparison photos below show exactly what I mean about quality of image with the new model at AGC LOW.
(unfortunately I didn't take screen grabs with the old version with AGC turned on because the noise annoyed me).
All Screen Grabs from both cameras are with the exact same equipment and cameras settings (except AGC on Low in the new model):
Meade SN10, EQ6 Mount, no filters, 0.8x FR. LENS sensup set at x1024 on all images.
I chose to capture the Video at DNR-3 in the old version and MEDIUM in the New version (which makes both cameras the same stacking rate)
EDIT: It appears that I accidentally had 3D-DNR turned off in the new 11811 model in these screen grabs
The ones with DNR Medium are in this thread: HERE
This first Screen Grab (Centaurus A Galaxy) is from the Old version 11673. I used to think it is pretty good for a little LN-300:
Now the exact same object with the new 11811:
This next Comparison is using M83 Southern Pinwheel Galaxy
Old 11673:
New 11811:
and this comparison using the Tarantula Nebula seems to show the difference better. All still at the same settings:
