Richard SargentParticipant
By coincidence David I also imaged PV Cep and the nebula last night. 50 x 1 minute exposures, I’ve just posted the result in the gallery. I agree with your comments on the current visibility of the nebula.

Richard SargentParticipantHi James,
I’ve just looked at my C14 OTA (which also has the two dovetails arrangement you described on yours) and although there are pairs of drilled holes with screws in at the locations you show in the second image they are only at the rear of the OTA and look to be for the finder. The distance between the holes is roughly a centimetre shorter than the distance between the mounting holes in the dovetail. I haven’t checked if the screws are the same size as those used with the dovetail, they might be smaller. So you would have to consider drilling and tapping holes in your C14 at front and rear of the OTA which would be way too scary a job for me!
Good luck, RichardRichard SargentParticipantSteve, I think the way out of this is for me to ask a big favour of both you and Ian Sharp. I would ask you both to delete ALL of your postings under this topic thread. As soon as that was done I would delete all of my postings leaving the thread free of ‘political’ postings that cause discomfort to some members.
Kind regards, RichardRichard SargentParticipantWe seem to have lost the posting that preceded the last posting by Steve but kept Steve’s? I would politely request the Moderators to remove this entire topic thread. It was never appropriate given that a) this is a website for astronomical contributions of an astronomical society and its members, and b) it introduced a non-astronomical, one might almost say political view and c) a view that is not shared by all members of the BAA thus a potential cause of friction. Please remove.
Richard SargentParticipantHi David,
I attach my image of Mr G taken last night but it’s only a 20 minute total exposure so doesn’t show things as clearly as yours. The fan shape is there plus a hint of the extension. I agree with Grant that the fan shape has been there a while. Indeed Mike H commented on it when he posted his image on 23rd November. However I need to check more of my images but I don’t think the fan shape was there before 9th November. So maybe the nebula is trying to return! I’m sure we will keep checking!Richard

Richard SargentParticipantFrom my measurements on 14th and 15th June it looks like RZ LMi’s latest outburst was late on the 15th. Data is in the BAA Photometry database.

Richard SargentParticipantAttachment shows measurements of ER UMa from a 2 hour period starting at approximately 22.00 hours UT last night. Each point is a block average of 6 ten second images.

Richard SargentParticipantHi Alex,
Observed via video cam on telescope from about a minute and a half before predicted time to 3 minutes after but no occultation seen.
Regards,
Richard
Richard SargentParticipantI was also lucky enough to observe the Titan/28 Sgr occultation, including the remarkable central re-brightening referred to above. As Saturn was low down I didn’t think I would be able to see the event from my suburban garden with surrounding houses and trees. So I needed altitude. Did I lug my telescope up a nearby mountain? No I took it to the upstairs front bedroom! See attached picture.
I observed with a 10 inch Newtonian on a Dobsonian mount, and made an audio recording to later time the event details. I recorded the occultation start at 22h 39m 44s and the finish at 22h 44m 59s and sent the results to Andy Hollis who was collating observations for the BAA. I still have his reply letter which noted observations received from about 70 observers.
The second picture attached shows Saturn above the rooftops (brightest object near frame centre). To the right of Saturn I have highlighted 28 Sgr with a couple of lines but it is faint on the picture. After observing the event I didn’t have far to go to get to bed! Yes I’ll be following the final news of the end of Cassini. Would be nice to view Saturn at the time of Cassini’s demise but I think it happens during daylight for us.
Thanks for the reminder Neil of what was a very interesting event.
Richard SargentParticipantI saw it too William. I watched the launch live on NASA TV and then went outside with a pair of binoculars. There was some broken cloud but then it appeared just as you described. I was expecting 2 points of light so when the binos showed four points travelling together at some speed I initially wondered if I was watching the lights of an aircraft! Anyway it was quite special to watch the launch and then about 20 minutes later to see the vehicle and its second stage pass through my evening sky. Thanks very much for posting the details in advance.
