What do you think?

Here is my first attempt at the Pleiades. Don't mind the noise as this is only 17 minutes of integration in a Bortle 8 area. This is the first time I've used a small refractor on this mount.

OTA: Skywatcher Evostar 72ED refractor

Camera: Unmodded Canon 650d

Mount: Skywatcher star adventurer

Subs: 30 seconds each at ISO 1600 w/ light pollution filter.

Stacked in DSS, processed with GIMP.

That's a very nice Pleiades, especially for the very short integration time. You will need more data to bring the noise down.

ISO 1600

Hi. Nice image. 

Maybe try ISO 800 and take as many frames as the cloud and your patience will allow.

Cheers

Nice job indeed.  I removed a bit of the red background noise and it looks really decent.  @alacant is right in that you should maybe try using ISO800.

Great pic! Especially with just 17 minutes worth of data! I agree with above that you should try ISO800 and see how that turns out.

I wonder if you shouldn't go down further still in iso. The stars are very bright and need short exposures at low iso/gain to avoid bloating. Also, at low iso there will be more dynamic range. If you take many more exposures (maybe 2 - 3 hrs worth), the lower noise will allow you a harder stretch to bring out the nebulosity.

Hi everyone.

Have a look here:

It maybe that the stars will saturate at any ISO value because they are inherently bright. I think there may be more noise below 800 when you stack. Nor sure of the technicalities...
