Histogram in APT for flats

[Danjc]

I'm having a play taking flats with APT and my 1100D and wondered if my Histogram and settings look ok.

I'm using an iPhone app against the lens that I can change the brightness on.

moving forward I will use an iPad against the scope but guess the Principe will be similar.

 

Cheers, Dan.

Looks good to me!

You could perhaps up the brightness a bit, but beware you don't cause any saturation in any of the channels. A brighter image means a better S/N ratio, but you can always simply take more exposures to compensate. As flats are taken at a short exposure time, that is not much of a pain.

Use the "flats assistant"!

It's in the "Tools" tab (I think)

Upped it a little.

The assistant only seems to work for CCD cameras.
