Thank you William. I have all the files in a single folder so that’s not an issue. I’ll work through the Windows tweaking and see if that helps. 

All the best,

After a couple more sessions I’ve managed to get a light curve. HOPS still stalled when calibrating the images even though they were acquired using the Atik software and not Nebulosity. I reduced the frames in AstroimageJ. So here’s my attempt, I failed to remove some dodgy images but HOPS even seems to take care of that.

Thanks again for your help William.

OK I’ll try that. I not had problems with other software using images captured by Nebulosity, but it is an annoying program in some respects.

Thanks William for all your help.

It works if the observation files are reduced separately, in the absence of an alternative this is probably the way to go.

[Martin Smith]

It’s a known target, KELT-8b.

Using 5 images alone reduction is swift, if I add the bias and dark frames it reduces OK too. With the images and flat frames only it takes a while but works. With all four the progam becomes unresponsive, after half an hour there is 20% progress with an unreponsive program warning.

I was able to process the sample data with no problem so presumably there is an issue with my raw image files. I’ve attached the FITS header from one of the files, it contains less information than the sample files. Is something critical missing?

[Martin Smith]

Thank you William, the test data is a good idea and will give it a go. The white space issue was covered in the installation guide and should not be a problem. I thought it might be a matter of giving enough time for processing, but I have tried being patient. Also the progress bar stays firmly at 0%. Another long time series planned for tonight so I’ll have time to try your suggestions.

Thanks again,

Martin

Hi Roger,

I’ve installed HOPS, and reinstalled following all the steps in the guide above (including checking Python).

HOPS opens OK and I can fill in the fields. When run, the reduction frames process OK but the program becomes unresponsive when it’s the turn of the observation frames, the dialogue reporting 0.0% processing. I tried a subset of the observations and some other frames from another run to no effect. 

Do you have any insight into this?

Many thanks,

Martin
