1" mono camera for Quattro 150p: 183mm, SV605MC or bite the bullet and go 533mm?

The IMX533 sensor is the better of the three choices you present.  I don't know how new you are to this hobby, but it's relatively cheap, easy to use, and you'll be able to use the 1.25" filters with it.

In my opinion, the 533 may be the best option for you.  I use the 183MM and with dark calibration, the amp glow is nat an issue for me. You can get around with the QE and choosing some useful sub exposure times will allow you to get some great images. I don't really care for their technical details that much, because I already own one (along with two 294MM based cameras) and feel no need to really upgrade to a better sensor at this point in time.

Although I much prefer the mono version, it might not be the best option for you. The filters are another expense (along with a filter wheel or drawer). Getting good ones isn't cheap either. So you have to take that into account. But you are so much more flexible and if you plan to do astro photography seriously, then this is the best way to go (in my opinion).

If you want to do OSC, then the 533MC is my recommendation. I don't own one, but it seems to be a good camera and people love it. The 6" quattro might not have a huge opening for larger sensors and with the two Newts I own, the 294MM already showed significantly more vignetting than the 183MM.

I have mixed feelings when I think about working with OSC cameras. I own a QHY 183c and a Touptek ATR CMOS 16000 KPA, which has the panasonic something sensor. Working with both cameras is always a bit challanging. The sensitivity of both sensors is much worse than that of all my mono cameras. So everything is a bit more complicated. Auto focus takes much longer and even plate solving sometimes is tricky. If the setup comes to the point of taking the subs, everything works, though. But then you have to take care of the moon. If it is more than 50% in size, you will get trouble getting fainter details. This problem is also there with mono cameras, but with the right filters, you are able to get useful data even in worse moon phases. Another point is, that stacking takes much longer with OSC data. But that's not a deal breaker.

I guess, a lot of OSC camera users may disagree with my thoughts, but once you knew the benefits of working with mono, you won't get back. (Although there are also some downsides).

I don't know about the SVBony cameras. But you usually get what you pay for. Their cameras are quite cheap and personally they are no option for me. My setups are out there 24/7 and I have to rely on a certain level of quality. I doubt, the SVBonys will work well over time. But I don't know.

So the 533MC may be a beginner friendly option. The 183MC is the color version of the 183MM, but I won't recommend it. The 183MM would be my preferred choice, but you have to buy additional equipment, too. So the decition is up to you.

People always recommend the 2600, which would be one of my dream cameras. It may be a very good camera, but the price is significanly higher. So I assume, for most users asking for "entry level" cameras, they are out of reach.

Hope this helps…

Trying not to overspend on cameras for my new Quattro 150p in the first round. I wonder, which is the better option: the amp-glow hammered, noisy, less QE ASI183MM or the banding-beaten SV605MC? How much data is lost thanks to banding?

The banding issue on the Svbony 533, has been sorted now, they have a new firmware in the camera along with another internal design fix, which all seem to have fixed the issue and they have re branded the newly fixed cameras with new serial numbers, I assume so they can tell them apart from the original ones with the issue…👍🏻

Many thanks for the replies, ended up with a demo version Altair 533M mono Tec camera at a handsome discount😎. Hope it goes all well, unfortunately weather hasn't been kind so far…

I like my 533MC over the 183MC.  I don't have to worry about dark frames or camera rotation.
