Day 7. How long will the Scottish weather continue to co-operate?

Mark PhillipsParticipantGreat update and works better on mobile too.
The homepage is mostly responsive but the top 4 buttons: Discover, Explore, Observe, Protect – aren’t. It doesn’t wrap round like other sections do.
One comment: I feel the observing sections would be better as a fixed set of navigation images rather than a scrolling one. Don’t like to have wait to get the one I want. I know I can get it from other navigation but it seems unnecessary to be like this to me.Good work though. As a web dev I know what’s involved.
MarkMark PhillipsParticipantIt’s pretty good actually. Here’s a video showing how to use it for comet photometry. Really easy to do but need to verify the results using this technique.

Mark PhillipsParticipantThat’s great. Thanks for your help and the tips.
The donation is listed in our archives in the Council Meeting minutes but I don’t think it would have been mentioned outside the Society much – if at all.

Mark PhillipsParticipantVery poor conditions tonight with drifting cloud and only enough gaps for 30s exposure, but clearly fainter.

Mark PhillipsParticipantI believe it’s this one and AstroImageJ gives me a V mag of 12.3.

Mark PhillipsParticipantI managed a couple of frames last night too and ran it through Muniwin (inexpertly!) and got 12.4 using a TR filter.
Mark PhillipsParticipantVersion 2.5.6 has now been released -there was another bug which caused a crash during the photometry stage.
You can also now see the bit depth of each star you select so that you don’t choose a saturated star by mistake (which also caused a crash).

When installing HOPS if you get an error: “The ordinal 242 could not be found in the dynamic link library” try the following:
It’s not a HOPS problem as such but an Anaconda one.
In the Windows/system32 directory find a file: libiomp5md.dll
Try renaming it to libiomp5md.dll.bak
I believe it is a file installed by other software which conflicts with Anaconda (not HOPS). Sorted it for me. Hope it does for you too.
21 January 2020 at 9:49 am in reply to: The quest for ET (Exoplanet Transits not Extra-Terrestrials that is) #581929Mark PhillipsParticipantHave done a couple of observations now and uploaded to ExoClock. The HOPS software is good and relatively simple to use, but I’ve discovered a slight flaw: If you choose a comparison star that is saturated, the software crashes. Have been in touch with the developers and this will almost certainly get resolved.
Obviously there’s no point in choosing a saturated star but if you do it by mistake (as I did) it crashes. There’s no facility to check the levels of the stars you selected yet so I used the AstroImageJ seeing profile tool. Hopefully something will get added to HOPS to avoid mistakes in future.
