Yep, with a 130mm refractor and ZWO 178MM.

How have you got the backspacing? Tried all sorts today with my Z61 and couldn't see the sun at all on screen with a 290mm. Visual it was fine. Started a thread because of it:

Got it around 14:36UTC with a Lunt LS80THA, TeleVue 2x PowerMate, ZWO ADC and QHYCCD QHY163MM:

 

Captured 500 frames @ 1ms exposure time, assisted by a Solar Scintillation Seeing Monitor (grabbing anything better than 2.5" seeing), stacked 25% with AutoStakkert!3. Post-processing with PSP (Unsharp-Mask), ImPPG (Lucy-Richardson Deconvolution, histogram inversion) and PSP again (colourize, vibrancy, mirror and crop).

Full resolution on my server.

Nothing special just :-

2'' diagonal -> Quark -> ZWO 178mm -> Firecapture software (1500 frames) -> AutoStakker (40% frames stacked) -> Photoshop (coloured added etc.)

I know the scopes may be different but I've tried exactly that and my 290mm doesn't see the sun at all. Guess I'll have to try again.

Very nicely captured
