Rosette - unguided, short subs

[vincentnm]

Hi All,

My guiding setups still misbehaving. The C9.25 wth a 3.3 reducer is probably not a good guidescope to use with the ED80 (imaging scope) ; too heavy. So I captured this unguided. I minute subs were showing traling, so I reduced it to 30s subs. Here's the result. Less than satisfactory for me actually. Need longer subs to get a smooth result.

Modded Canon 350D, ED80, EQ6

ISO 1600

30s X 128 subs

Stacked in DSS

Stretched in PS CS3. Tried Layer masks for the first time to apply different processing for the background.

Thanks,

Vincent Morris.
