brilliant thanks

thanks where do i turn it off please

unfortunately cannot post in pi forum as still awaiting approval cheers

hi all just upgraded to the latest version of pi but now when i run the wbpp script it runs fine till it gets to the plate solving reference frames part, then looks like it would take hours to complete this part,never noticed this on the previous version ,any help appreciated ,thanks

Thanks guys and comments on colour or mono camera please 

Will try thanks

I've captured Comets with just a camera and a 55mm lens.

Have a go with the equipment you have if that's what you have.

Try the FOV calculator to see how tight you might be on the comet versus the surrounding star field.

Thanks, could not find a fov calculator where you can add comets

hi just wondered if anyone has any thoughts on this setup for capturing a few comets or is it too wide field thanks

Sorry, bit late to this one, so you have probably already sorted everything.  Don't have the 26m but a 533.  You can run the sensor analysis in sharpcap, which would give you some info.  In NINA I have the following set.

High gain mode = on

Ultra mode = on

high fullwell mode = on

usb limit = 2

Dew heater = 4

fan speed = 1

Gain i have found reasonable results at 300 and 500 with an offset of 120 depending on how bright the object is.

Thanks Sinbad using gain of 100 how did you come to use 300 please 

thanks guys struggling if anyone fancies a go at the xsif 😶

thanks Alan,actually used  dbe-sorry  abe

been processing this for a while now so dont want to start again so how would you darken the back ground in pixinsight thanks

Thanks Phil

I have the colour version of the Altair IMX571 camera and use nina with the default Gain 100 and Offset 275, HGC mode on and generally 180s exposures in Bortle 4 with no filters. This seems to work well for me.

Thanks Phil how did you get the 275 figure for offset

thanks

hi just took some darks with my new cmos camera (imx 571 sensor) stretched in PI but doesnt look as good as my old ccd atik 414ex camera,any thoughts please or am i looking into it too much 

the new altair camera

old atik 414ex

probably a better image on these downloads to see

I have a RisingCam 571 OSC camera (Touptek clone) running with NINA, the settings I use are:

Gain 100

Offset 768

USB limit 2

I run the camera at -10 deg C and use 2 min exposures for Broadband imaging and 3 min exposure for NB (dual band filter).

 

thanks tomato how did you come to 768 please

My guess is that it's the low number of subs that prevented adequate pixel rejection. As the OP wrote, the purpose of the test was to evaluate settings, not to create a final image. The settings look ok to me.

Thanks 

Hi gorann it's the Altair astro version and I didn't use any darks or dithering which doesn't help cheers  and -10 c

Clearly the camera works but there is a striking amount of hot pixels. What brand of IMX571 camera is it and what was the sensor temperature? My ASI2600MC (got three) and Omegon vetec 571C appear to have considerably less hot pixels (at -10°C).

Thanks tomato another fine piece of processing need to take some darks and get a master dark I can use for a while as each sub is 50 mb to reduce processing time and learn how to dither thanks 

Thanks budgie this wasn't a screen shot of mine just 1 i could use as an example mine is set to mono and I think I had mine set to 50 initially as default, not sure why I changed it to  0 but thanks for the reply 👍 cc'd was much easier 😗

hi had varying opinions but just wondered if anyone can tell me the camera settings they are using in nina for this camera /sensor,specifically the default offset ,using an altair astro 26m but suspect the 2600 and other versions will be the same,im using 0 for default offset and not 50 as in image, and also fan 1 instead of 0 in the image ,thanks  please ignore arrow
