Ngc 5128

[bluesilver]

Had a go at NGC 5128 a few nights ago from my newly built roll of roof observatory.
Not the cleanest image, I messed up my flats and darks a bit when i tool them.
38 x 180 second exposures
asi2600mc no filters, gain 101 at -15c
Esprit 150

Next time i will pay a bit more attention when taking the calibration frames.

Great result in all and sundry.
Well done.
Nice Cent A.

That’s great Peter! Fantastic detail through the core and you picked up the blue mohawk too. Nice job!

Peter,
An excellent Centaurus A exposing some nice faint detail either end of the main core structure
Well done !!
Sorry to hear you’re still having a bit of trouble with calibration on the 2600MC , it took me months and months to nail it and now it’s normal routine which works beautifully.
Also the 2600MC has negligible dark current even cooled to -5C , to save you a bit of wait time during cooling process -10C is more than adequate, I’ve used -10C since I’ve had the camera ( August 2020 ) and it’s perfectly fine for 30 sec to + 300sec subs
Cheers

Thanks for all the comments, appreciated.
I think i may be onto the calibration issues with the asi2600mc.
Just got to wait for some more clear skies to try them out.

Fantastic shot Peter, the detail is superb.
I took the proffered advice and use just bias and flats for the 2600mc, one of the many joys of the imx571.
