Hi William. I was pleased to read your helpful comments. Thanks.
One of my follow up remarks on progress was also lost. The dome connected fine with the Pulsar ASCOM Driver and i could use the buttons to move the dome, but EQMOD would not connect to NINA, although it was connected with SkyMapPro and SharpCap. Thus the telescope and Dome were not talking.Im pleased to report a solution:
At a recent meeting of my local AS: Abingdon, a software engineer suggested it was likely down to “permissions”. Both SharpCap and SkyMapPro were run as Administrator (on my system), NINA was not. Ive now corrected this and hey-presto! the dome can now follow the telescope.Im still in ASCOM 6 but NINA warns.
Hi Grant. I wanted not avoid making a lot of changes. The next step would be to go up the ASCOM 7
I have v6 on two W10 machines, one is in general use that i use as a test base, the other is the one i use in the OBS.
I will update one at a time.NB I see William Bristow has replied, but i don’t his message. The system has only logged one reply from Grant.

Thank you Bill. This extra info is very helpful. His Pluckley address coincides with some reported Occultations in the attachment.
All the best.Attachments:
Too add: The Lunar Section circular of 1975 Nov. is an interesting read: https://britastro.org/wp-content/uploads/2019/04/Lunar-Section-Circular-1975-11.pdf. E. Moore presented a paper at the Reading Meeting. I was not at that meeting though.
Sorry i can seem to get the image to show up. Try this:

Thank you to observers who were clouded out.Attachments:
Alex, Nick,
It was mostly clear here. I had a view though double glazing. The telescope is not accessible atm. Temperature was touching -5.5 in North Oxfordshire.
Alex: The Atlas step is very clear at 7/100 sec. Its been ages since a decent M45 passage.Take care Alex on the garden ice rink. I have some over-shoe crampons. Last used in the Alps!
Best of luck. Its gonna be cold.
TimI would like to thanks those planning or attempting observation of this remarkable asteroid pairing, and to those passing on information to possible observers. We where clouded-out, which was disappointing, but at least we tried:

A Cook nr Newtown
T Haymes nr Banbury

Thin cloud prevented a good view of both the D and R. So no observation to report from North Oxfordshire
Thanks for the update Alex, i am looking forward to the Saturn occultation. Best of luck to all.
Please send reports to me: tvh dot observatory AT btinternet com, or the lunar Section Director.The email address occultations AT stargazer.me.uk no longer exists.
For the Atlas Graze, here is a link to zip file with the limb profile, text file, and the Google Earth mean limb. (computed with Occult4 )
For best view, observer from anywhere between 1 and 9km inside the mean limb. If you are on the mean limb line – there is no occultation !
The limb is very rugged and lots of ins-and-outs should be seen.I hope the shared link works 😉

Lunar Section Occultation Coordinator.Denis, I did sign that petition.
There is a Dundee Council survey form linked to the link i gave, which provides boxes for comments.
Cheers…HaHa. No observatory is complete without a fire extinguisher at the ready !
Yes the 902H Ultimate is sensitive but a bit noisy i believe. It will need a 12V DC supply and a phono cable ( also a BNC plug to phono maybe).
Ive not used one, but it may be possible to smooth out some noise when processing the video (Binning)
Feel free to contact the Section.Tim
Asteroids and Remote Planets Section (Occultations)Hi Lars,
Perhaps you have a WAT-902 ? Yes this could be used. My setup is:
Camera => GPSBOXSPRITE-3 (Time overlay) => Pinnacle Dazzle video digitizer (for W10/11) => Laptop with IOTA video capture.
Free software: IOTA capture, Tangra (Hristo Pavlov) for video analysis. (light curve and timed event).There are on-line sources for brighter predictions E.G. asteroidoccultations.com, but I use OccultWatcher (free software) which takes predictions from a server. I then filter them down to the ones near me.
Happy to help out.
My setup in 1991 with DIY video. Your WATEC would have the same sensitivity.

I observed from a carpark at Beacon Hill Hillfort just off the A34 South of Newbury. It was close to the mid-shadow line. Transparency was poor with thin cloud moving through but it was clear enough to see the pole star and the major constellations.
Equipped with a Vixen Polarie and WAT-910HX + 135mm F2.8 lens attached, i was able to find the target by star hopping. To do this I compared SkyMapPro and the video display. The occultation itself was not seen live on the monitor. When i got home, I analysed the AVI recording. There is a small brief dip at the predicted time. No fade was recorded.
It was more of challenge than i had expected, and i was pleased that the 50 mile drive from home resulted with a successful recording although no clear event.
Hi Jeremy,
Thanks for the comment. I’ve asked for clarification on the magnitude sources. The magnitude drop could be smaller than anticipated, owing to the “partial eclipse”. So a visual observer might not see any change – but without observing, we dont know. I video camera would be preferable to catch the drop.
