SXVR-H694 flat with 1.25" filters and OAG

[dmahon]

In case anyone is interested, here's my master flat from my SXVR-H694 taken through a SX filterwheel populated with 1.25" filters together with an SX OAG.

There's some vignetting in the corners, but nothing that's going to make me buy bigger filters.

Thanks for the picture, but which of your telescopes did you use for the flat?

Looks good Dave - pleased the camera's arrived at last - I'm dead jealous!

Just in time for the period of the year with no astronomical darkness!

Now of course I need to plan what to get next. Having a bit of difficulty with focusmax and my cheap skywatcher autofocus (after correctly calibrating itself, it just locks up when trying to run a Vcurve). Will try it on a different laptop next time out, but am considering some kind of stepper motor based automation instead.

Thanks for the info. That means the vignetting is neglible with 1.25" filters at F5 which is good news.
