The extended full well mode might be best for something like 47 Tuc with its super bright core.

For what it is worth that fine noise grain seems very much like what I see on my Sony A7riii which has a similar architecture sensor (BSI 42.4mp).

I wasn't that impressed with the sensitivity in the deep well mode...in any event the core is easily fixed by a couple of shorter subs. I still find it weird users can vary the gain/offset. But agree experimentation is worth while.

Ta M&T. The FSQ106 works well with this sensor...which samples the scene beautifully. That said, I'll eventually move the camera up the aperture totem pole once I better understand the value in its various readout modes.

Simply wonderful! Can I ask which scope you used for this? The Tak?

By the way, your fantastic Nebula award winning image of NGC 3576 has set admiring tongues wagging down here in Tassie. Of course, you should be called peter AWARD, lol. It's a joy to behold such incredible deep sky imagery.

Cheers,

Thanks Richard. As you may have guessed (but I did mention this on the web page) I used a Takahashi FSQ106 EDXIII As for those glittering prizes...I've shamelessly listed a few of them here along with some other shenanigans.
