Description

Seven 1200 second 7nm Ha exposures stacked and some noise reducion - I am experimenting with getting good spacing for the Televue TRF2008 reducer flattener on my Orion ED80T-CF and SBIG ST-8300M/CFW8 imaging setup.

This spacing is using the Baader 7.5mm spacer only - it gives an approx spacing of 45mm, 12 less than the recommended? so I don't think I'm getting full reduction - but it's certainly better than none.

I'd done same just using the AstroTech field flattener so thought this woul make for best 'same-same' comparison of field.
