Hi Terry,

Nice work. Like you, I also managed some simultaneous photometry last night. I used my transformed V-band image in ISIS to create a flux calibrated version similar to yours. I think it serves to provide a useful comparison.

Cheers,

Paul

Has anyone successfully viewed additional CALSPEC profiles (available from http://www.stsci.edu/hst/observatory/crds/calspec.html) in ISIS?

I'm receiving the "not a valid 1D FITS file" message when I've tried to load a couple of examples.

An update (click to enlarge):

I've discovered a work around. I noticed that when the SIMBAD look up fails, ISIS presents a dialogue asking to continue using some arbitrary coordinates. I noticed that the coordinates it suggests are identical to what the last values are in the heliocentric correction dialogue. So just by entering...

Thanks Olivier and Etienne, The challenge with this nova is the stormy weather (it's winter in Australia). I've had to open the hatch of my observatory a little bit to take some spectra when the clouds clear, and then be prepared to close up quickly before the next shower. It keeps me on my toes. Paul

Emissions brightening steadily over the past 5 nights (click to enlarge).

I've run into issue when trying to specify an object name in ISIS in order for the Auto Atmosphere / AOD function to access SIMBAD. How does one do this for objects that don't exist in SIMBAD, e.g. novae? I've tried specifying a star close to the target of interest, which works - except the FITs hea...

Thanks Tim, this just keeps getting better and better. A simple and effective tool -thanks !

Here's the instrument and atmosphere corrected profile.

Confirmed (instrument response corrected version coming later). The next week's forecast for me is rain, hopefully others can follow up in the coming days.
