Red Rectangle + Ghost of Jupiter planetaries

SPX350 F4.5, Mintron (GStar-Ex), Astrodon filters.

Always wanted a go at the Red Rec (F12.3) as it is so unusually symmetrical with central star mag9.0, in Ha it should show its full size but Mintron was not sensitive enough with Ha or IR filters to show anything as it really needs a 16bit cooled CCD and longer exposure to develop this to its fullest.

Ghost of Jupiter (F16.3)came out well as this is a really big bright planetary, does not resemble Jupiter but does resemble the Blue Snowball in Andromeda.

Had another go at the extremely bright Spirograph (F29) in Lepus this time at a 10meter long fl showing the slightly broken ends of the ellipse shape.

Thanks, John.
