Michael O’ConnellParticipantWishing you all clear skies and the best of luck with this event.
Unfortunately I’m too far west for this one.
For anyone lucky enough to be under the shadow path and who hasn’t tried observing an asteroid occultation previously, it’s a great time to give it a try.
Michael.
Michael O’ConnellParticipantThanks Richard and Peter.
I really enjoyed watching this asteroid moving ‘live’ – a rare sight.
Michael O’ConnellParticipantYea, T-Point is excellent.
I have a small Watec camera on the back of my C14 (with a couple of focal reducers).
After using about 20-25 stars for a T-Point model, it puts the target object in the centre of the little chip every time.
Michael.
Michael O’ConnellParticipantGrant,
I don’t know for sure, but it is something I always do with my Paramount when using TheSkyX.
Worth a try IMHO.
Michael.
Michael O’ConnellParticipantGrant,
Do you sync on the first star each time you start up the mount?
Regards,
Michael.
Michael O’ConnellParticipantI have to agree with the other here and say I enjoy the paper copy.
Michael.
Michael O’ConnellParticipantMany thanks for the recording. Great to watch the event.
Massive thanks also to all those involved in running the Association. I know the last couple of years in particular have been challenging for a number of reasons, so massive thanks to you all for your tireless efforts.
Michael.

Michael O’ConnellParticipantBest of luck with this event folks.
Hope the weather cooperates.
Michael.
Michael O’ConnellParticipantThanks Nick.
Thanks David. I’ll have a read of your article.
Michael O’ConnellParticipantThanks folks.
Nick, that procedure seems quite an effort.
At this stage, I’m thinking of leaning towards piggyback as it is easier to configure and adjust.
Problem is the cost of these rings and saddles…
Michael.
Michael O’ConnellParticipantThanks for the link Paul.
Impressive setup!
Are they Parallax Rings on the 400mm?
Michael.
Michael O’ConnellParticipantThanks folks,
What hardware do you use for the piggyback mounting?
Regards,
Michael.
Michael O’ConnellParticipantAgreed, I place it just behind the corrector plate.
Michael.
Michael O’ConnellParticipantThanks Jack for the heads-up.
Looks quite comprehensive.
Just ordered it.
Michael.
Michael O’ConnellParticipantI use a UPS in my observatory as well.
Mains power feeds in to the UPS. All devices, or your select chosen devices, then connect to the UPS.
It is meant to be on all the time, otherwise it can’t prevent an interruption in the mains power supply.
Michael O’ConnellParticipantView from Kildare, Ireland this morning

Michael O’ConnellParticipantVery nice Robin! Very nice!
Now just drive there and cross-check the speed on the dial to make sure…
Michael.

Michael O’ConnellParticipantTo clarify my above point, I get a long error message just when the program opens.
The error is contained in a separate window to the main application.
Also occurs with V0.12 shared above.
Anyone else get it?

Michael O’ConnellParticipantYes, that works for me now as well. Thanks Nick!
@Maxim: Is there any chance we would get this program to open 8-fits files directly please?
I have a little project in mind involving images from the Global Meteor Network pi camera.
Thanks,
Michael.

Michael O’ConnellParticipantI can get the program to run now, but when I open an image, only the FITS header loads in the lower panel – the image itself does not load.
I note that the Command Prompt window states the following:
