Disappointing Asi 183 mc pro for planetary imagimg

Tirant

Hello
One year ago I adquired a 183 mc pro camera, in order to do DSO imaging, and having in mind an alternative use for planetary imaging. There are other camera models that perform better than this, but I expected a good was expecting a good performance, better than the first camera I have, 120mc-s model. 183 has more sensitivity, Qe, resolution, and has a 4/5 star ranking for planetary work, as anyone can see in this comparison, which appears on the web
https://compare.astronomy-imaging-camera.com/.
So in these last weeks I am using the 183 camera and its performance is very poor, compared to the 120, because it lacks a lot of sensitivity. I have years of experience with the use of astronomical cameras and I do not know what is the cause of this problem, maybe it is my own camera, or.a firmware/software problem or a general problem with this model, in which case it should not be advertised as a good planetary camera. In my case, I would like to use for everything, DSO and planetary, and if it does not work well in planetary, the manufacturer should give a solution or fix the problem. In fact the normal version of 183 is used and advertised as a good planetary camera. Is there any solution ? What should I do?

Hi Tirant, with respect to the mono version, 183MM pro, I am very pleased with the results.

Obtained with a 14" SCT at f/10

I am not sure what your issue is, Been using the 183MC Pro for high res Lunar work for over a year, never a problem at all.

We need more detail on your imaging train. This sounds more like error on a different end.

Hello both, thanks for your responses. When I was talking about planetary imaging, I was referring to all kinds of planets, the Moon and Mars are, together with Venus, the ones that have the most brightness per unit area and therefore there is no problem of lack of sensitivity. But I tried to capture Jupiter and couldn't get a decent high frame rate at the expense of raising the gain to an unacceptable level, and Saturn .. unreachable. Of course, it doesn't even occur to me to try Uranus or Neptune. Also, António, usually the monochrome versions are more sensitive, mine is the colour version. About my imaging train, here I upload an image with the telescope and camera setup that I normally use. To reach the focal length f: 25 I use a barlow gso 2.5. As you can see, with the 120 mc-s, I can go up to 80-90 fps with a gain of 38/100 and a frame of 320x240 pixels. With 183, I'm not even halfway there.

Tirant Hi again, I would give it a try at f/10 that is removing the barlow. 183 pixels are smaller, and for jupiter (the planet I image the most) I use gain 300, 8 bit, and speed up to 80% histogram. Mono version, but with in train filters.

Hello , António. Thank you for your advice. My intention was not to contradict anyone, but rather to give a touch of attention to the problem, because the 183 in theory is higher than the 120 and I see that it is the other way around. There is little left to be able to observe Jupiter properly, but I will try to do a test. A pleasure talking to you, I know you have a lot of experience on the subject and years of dedication.
Best regards
