Stellarium vs theskylive.com for comet position

[kosborn]

I'm hoping to catch an image of 21P/Giacobini-Zinner before it fades too much more (assuming the skies clear at some stage). Stellarium reports the current position at 7h09min27.26s and -17d32m3.5s (J2000) but theskylive.com says 7h16m8s and -17d24m10s. Unfortunately with my OTA and camera these positions are not in the same FOV.


Does anyone know which one is accurate?


Thanks, Kevin

Hi Kevin

I'm definitely no expert but will this help?

Thanks Paul,


That does help. Different to both of the others but the Calsky data gives me a bit more confidence. Will aim there and keep my fingers crossed... Hopefully it will be bright enough to see on individual subs in case I need to aim elsewhere.

Cheers - clear skies - and good luck!
