is my sensor out of alignment?
Hi,
Since owning my FLI 8300 I have struggled to get a decent shot. Most of them have hideous gradients despite using different scopes/adaptors/flatteners/correctors combos.
The other day I tried again and started shooting light box flats then sky flats and then wondered why the illumination was totally asymmetrical on each filter.
(This was with SX filter wheel and 31mm filters). The SXFW seems to be lining up the filters ok so tonight I bought the camera in and shot with filter wheel and no scope just ambient light 1 sec subs at -30.
As you can see I have a horrendous gradient across the sensor.
Does this mean my sensor needs re-alignment?
Please advise.
These are lum, RG shots, bright being lum. Ha and blue failed to load so I will try and shrink these and post later. AstronomiK filters.
Thanks
Graham
