With how the ASI533 is still fairly new, thought another example for others to see wouldn't be a bad thing to have.

 

I've been lucky with a string of clear enough nights with good enough seeing to shoot this target over multiple nights. 

This is 4 day of images with only part of the night dedicated to this target.  Trying to go deeper, I used a longer exposure than normal but also shot some short subs so I could use HDR to recover the tops.

I'm looking forward to revisiting this one in the future when I can get a mono setup going.

It looks great. Can't wait to use mine but the weather here does not cooperate.

Thanks for sharing as it makes me more confident I made the right choice buying this camera.

I'm very happy with it. I just really really wish there was a mono equivalent that was affordable (the 6200 is lovely for those with very deep pockets...which mine are not:P)

Very nice image but I am very surprised that with 17.5 hrs of total exposure and there is not as much Ha as I would have expected.

I only have limited experience in the astro world. I'm not sure if this is typical or not of OSC vs mono which has much better throughput with the filter plus way more efficient use of pixel area (25% of the sensor). I'd imagine the dyes used for the bayer matrix is pretty standard between sensors.   That's my guess. But I'll default to others more experienced in the field.

Nice image.  

 

I hope to get a break in the weather so I can give my ASI-533MC-Pro some sky time.

DrG : A nice first try on this object. This is fairly bright and I have a feeling you may have clipped highlights. Either during acquisition or during processing. Here is one image I got in 2018. It has only 42 minutes of total integration time with the dual narrowband filter and the colors are all there. Even though my image is nothing to write home about, it illustrates how bright this object is. Cheers ...... Anil
