Hi,

I am considering a switch from OSC to mono.

I have an Sbig ST8300C, this is a really nice camera, and I have had zero issues with it, but since I am the centre of a large regional city - Geelong, I have become a bit frustrated with colour imaging due light pollution and the resultant gradients that arise. These are made worse since in Geelong, late in the evening, we seem to get a lot of moist air that reduces transparency and reflects the cities light.

I figure I would be most productive if I went narrow band - primarily H Alpha...

I have a couple of options:

Get a new mono cam - max budget around $2500, keep ST8300c- perhaps combining OSC images with H Alpha.


Sell St8300C, Get new Mono cam max budget around $3500 (assuming I got $1000 for ST8300C in the classifieds.)

Camera choice seems to be:

QHY9
Atik 414EX
Atik 428EX
Atik 383L+

Cant see much around the $3500 mark... More $ is not really an option.

The 414 and 428 are small chips, but have hugely better QE than KAF8300 chips particularly at H Alpha band..... the main difference between them seems to be pixel size

I will be imaging at around 600mm,950mm and 1800mm.

So if narrow band is the choice, what would you do.....??

cheers
Gary
