I have a Lunt LS60T ( serial No. 2012504) with a second stack filter ( LS60F - Serial No. 0000446) . I am experiencing two ghost-images when viewing the Sun. Is this something that I can simply adjust ? Or do I need to have this repaired ?
Can anyone assist me with this in Australia? I an guessing that LUNT no longer carries out service/ repairs of these instruments

thanks

Graeme
