Re: [APML] OT:Iris Nebula

Hi Stuart

Thank you,I have a cross of plastic sticks aproximatly 5mm in diameter permanently mounted on the dew shield,

I used to take them off after focusing,but after a while I realy started to like the look,and left them on the scope during imaging.

Wolfgang, I would echo the praise you've received already - a beautifully rendered image! How do you get such pronounced diffraction spikes on an SCT? Are you adding string cross-hairs like Rob Gendler has done on his refractor?
