so i used sequator to stack my telescope w/phone images and i got about 3mins 1.3subs and processed it on siril i ended up with a reddish center. i was capturing the ring nebula and i want to show the pictures but its in my profile just scroll down thanks :)
i tried stacking in sequator and processing in siril to see what will happen and my image turns ito red at the center but not at edge im new to stacking and process thingy thanks!
all taken on a phone attached on the telescope!
can i ask for some advice on how to make it clearer it was processed on pipp and autostakkert4 but it seems quite blurry its a 76mm telescope i know its small but im making the most out of it :>
