Thanks Eric and Paul,

With the amazing Photometric and Spectrophotometric colour calibration processes in PixInsight these days I’m pretty sure it will all work out fine.

Cheers
Ian.

Hi all,

There has been quite a healthy discussion on this in the AAVSO forums and it seems that the answer is yes – there should be no problems doing this.

I’d still be interested in any experiences on this.

Cheers
Ian.

Thanks Robin,

A great setup and some nice results!

On a less expensive note, I’m just about to upgrade my system at PixelSkies in Spain to a C11 Edge HD with RVB photometric filters (from a 104mm APO I have at present). No spectrograph though!
Cheers
Ian.

Hi all,

Clear last night. Managed to get a few exposures early on. Average mag. over 8 x 20 second exposures was 8.133 +/- 0.030. This was with no filter.

Equipment: C9.25 @ f/. SX TRIUS 694 Pro CCD, Calibrated with Bias, Flats and Darks. Photometry processing in AstroArt 7.

Cheers

Ian.
