Dso camera

[warm cedar]

Budget: 1000$
I was thinking about buying an ASI183 Pro

[weak blaze]

there are better cooled cameras < $1000. The IMX183 sensor that's in the ASI183 is a first generation sony backlit sensor. It's also on the small side. You might instead be interested in cameras with the IMX585 or IMX533 sensor. Both are far newer tech platforms, have much better noise characteristics, and are physically larger than the 183.

Hmm

Oh the camera comes with AFW 8X1.25"+1.25"LRGBSHO filters comes at under 1k$?

Damn

[sonic hound]

wait is the 183 larger than the 585?

[weak blaze]

Oof yea I misremembered the size ratio of the 183. The 183 is large than the 585. Funnily enough I have cameras on my desk with all 3 of these sensors. Here are side by sides with the 183 and 585 and 183 and 533. The 183 is on the left.

So it would be worth knowing what kind of telescope the camera would be going on

The 183 is pretty annoying to deal with, with very bad amp glow. A trait of its older design.

Forget about old tech

The mono bundle I sent has the best price to value ratio. Unless you can find something better used

[sonic hound]

Nice

[sonic hound]

Yep

I bought the 585 mono

Cant wait

Uhh. Well ill probably be using my 1200mm newtonian and maybe the smaller 400mm one

[weak blaze]

Ok well, looooong focal length plus small sensor means a very small field of view. You should use tools such as those at https://astronomy.tools/calculators/field_of_view/ to assess what the FOV will be for a given optical and camera combination

A sensor such as the 585 may be too small to work with on the newt unless your goal there is lunar or planetary. However it may be quite fine on the 400mm focal length telescope

[warm cedar]

Oof

I haven't thought of that

[copper wagon]

Its not that tight

its workable

to piggyback off this thread, im considering getting a 585 sensor to pair with my quattro 200p... im still very much a beginner but my understanding is that pixel scale is key here; i would get around 0,7 arcsecs/px
would that be fine or should i just go for something with bigger pixels? from what ive read a lot of this is down to atmospheric seeing but i really dont know how to gauge how good it is for my skies...

[weak blaze]

I would instead consider something like the 533. It would be more appropriate for an 8" newt and you will appreciate the larger FOV, and pixel size, because of it

you can use the astronomy.tools site to go through optic and camera combinations to know the FOV

here is an example of the 200p, assuming a 1x coma corrector, with the 533 and 585 https://astronomy.tools/calculators/field_of_view/?fov[]=33||9791||1|1|0&fov[]=33||3106||1|1|0&messier=42

The 533 does indeed seem like the better option but I'm not ecstatic about the square sensor, not to mention the ToupTek bundle is like an extra $500 lol
