Lars LindhardParticipantThe weather will not permit observations/pictures from the next 180 hours, I’m afraid.
Lars LindhardParticipantI received the October JBAA plus Handbook 23. October.
Lars LindhardParticipantI agree.
These “Sovjet-type” elections with only one candidate are pointless and waste of money.
Lars LindhardParticipantThank you for your advice. I will find a full-aperture filter for the objective.
Lars LindhardParticipantCan you tell anything about the costs? There must be a monhtly rent or something? and what is your price for the equipment?
Lars LindhardParticipantAny explanation for the drop in blue magnitude?
Lars LindhardParticipantVery interesting thread.
Could I make useful spectra of the SN with my StarAnalyzer 100?
Lars LindhardParticipantEach of the planetary sections has templates on their websites on which you can draw the features and record other important details. The Saturn section has a series of templates depending on the angle of the rings (which you can look up in the Handbook). See: https://britastro.org/section_information_/saturn-uranus-and-neptune-section-overview/observing-programme/saturn-uranus-and-neptune-visual-report-forms
Regarding phases,in the case of Venus the observed phase generally differs slightly from the calculated one, a phenomenon called the phase effect: https://britastro.org/2016/the-phases-of-venus. So the phase should be drawn in at the eyepiece. The time of dichotomy can be determined from your observations and compared to the predicted time.
It seems that the links to Uranus and Neptune observing forms are dead.
The negative Saturn tilt forms link to the positive forms, but I suppose they are identical?
Lars LindhardParticipantThank you, All, for good advice. I will study your suggestions.

Lars LindhardParticipantIt seems that the replacement PDFs with 2022 Handbook Errata got lost in the process
Lars LindhardParticipantIt seems that your observatory is (very?) close to the active volcano-area?
Do you expect problems with that?

Lars LindhardParticipantI guess there is a bit more “Breaking news!” over a mag 5 nova than a mag 16 comet… 🙂
Lars LindhardParticipant
The nova is still about mag 11.
Here is a picture taken tonight about midnight here (UT + 2) 14″ sct + Canon 77d 10 sek.
Lars LindhardParticipantI saw it visually on 16. july 22.30 UT. Mag about 12.
