Thanks for the info Gary I got it while doing photometry on TCrb

I used a plate solved image of NGC654 which was oriented N up E to the right. I used the N up E left tick button which corrected it to N up E left. With your image of M101 it greys out like you say and can be brought back by clicking the north button at the bottom of the screen. I see the image is nearly corrected at the proper orientation and is Plate solved. There is an Aladin manual ver 10 available on the website maybe there’s more info about this in there
PeterHi Robin
Just click the View tab on the top menu there you will see a north up East left, just tick that, short cut Alt+X
This works in my ver 12

Hi Lyn here is an image I took this afternoon Wed Apr 20 2022 13:25UT with 102mm Skywatcher startravel refractor and Canon 600D

Great news Daryl let’s hope planets are found around Alpha Centauri A and B that would be three solar systems on our door step!
Really enjoyed the meeting which I watched on YouTube last night. The two Ladies who gave the talks on the Multiverse and the Winchcombe meteorite were excellent. I had to agree with Nick James on his sky notes wouldn’t it be great if the Hubble space telescope could be upgraded with new state of the art instruments, or would the cost be a bit prohibitive what with all the other upgrades it would need. I think I will hide under the stairs when launch day comes for JWST!

I performed Aperture photometry in IRIS on the G channel of the source AT2021afpi Wed Dec 1 2021 18:45UT. I used the 12.2 and 13.2 comparison stars on the AAVSO chart X27438A. I got the magnitude at 12.8m
Mon June 14 23:35UT I get the Nova at 9.0m using the 8.5 and 9.4 comparison stars IRIS was used for Aperture photometry

Hi Nick same here up in Sheffield I have got my 102mm star travel refractor and Canon 1100D set up ready to go lets hope for a few breaks

High resolution images of Betelgeuse are available on the ESO website showing before and after images of the surface taken with the Sphere instrument .Could it be dust that is causing the dimming. hears the link https://www.eso.org/public/news/eso2003/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+EsoTopNews+%28ESO+Top+News%29

Hi David
Its unbelievable that this has never been noticed by Amateurs. But like you say your wife spotted it. Its probable that we are so used to the bright star pattern of Orion that the arrow as gone unnoticed, I bet there’s lots of these asterisms to be discovered. I will have a look next clear night but might struggle with eta with the light pollution around here. Might take my wife out to a dark sight and see if she can spot anything!

Hi Kevin
The spectra are dynamic like you say, are the strong emission lines early on due to mass transfer from the red dwarf onto an accretion disk around the white dwarf, causing disk instability and increase in light. Or does matter impinge onto the surface of the white dwarf increasing the systems light output, or is it a bit of both. Probably am i right in saying its a little more complicated than that. Anyway nice piece of work

Is it possible that objects like Borisov, asteroids, comets, even free floating planets permeate the vast regions of interstellar space. So objects like Borisov and Oumuamua are like nomads of the Galaxy having chance encounters with other Solar systems. If this is the case wouldn’t it be difficult to pin down the home star of these objects. Would more of them have a tendency to enter the Solar system from the direction of the Solar apex, the 19.5Km/sec motion of the Sun through space.
