... I put a picture of one of the novae in Scutum in the files section (under my folder under the user_folders folder) some time back in October. I was still...
Forums been quiet of late..... With the Bresser Skylux scope bought last week at UK Lidl Stores came a barlow-like tube that isn't! It contains centrally a...
I bet that has got some new Skylux owners confused! Your setup is similar to to this http://mysite.wanadoo-members.co.uk/astro2/spectroscopy_4.htm Have you...
... Sure would and I suspect despite great efforts here 'below the radar' of many informed amateurs too. Can't win them all although we try;-) ... Yes - very...
I was pleased to get a spectrum of this object using just a 200mm aperture. It is the remotest object I have imaged and the faintest spectrum recorded to date....
Many congrats Robin - it's a much better profile than mine at http://www.astroman.fsnet.co.uk/hotq.htm and may be tempted to try again as it's currently well...
Thanks Maurice, Yes it is pretty much overhead after midnight so ideally placed. I think I am getting close to the limit now with 8 inch aperture. The spectrum...
Robin - you've certainly cracked the multiple-stack routine to get these long effective exposures. Well done. You perhaps need to move up the aperture stakes...
Hi all A new version of Visual Spec is out. See Valerie Desnoux post on spectro-l below Robin ... From: valérie desnoux To: spectro-l@yahoogroups. com Sent:...
I have been experimenting with a setup to try to record a solar spectrum just before totality during the March total eclipse, using Baader Astrosolar film as a...
Robin - I used a lo-grade [relatively inefficient] transmission grating visually for 1996[?] total in India on the final crescent but shaded the zero order...
Hi Maurice, Oh, the first priority is definitely to enjoy the event (having been clouded out in France in 1999 with only a couple of minutes to go.) I will...
If anyone finds a gap in the clouds, reccurent Nova RS Ophiuchi is in outburst. Brighter than recent outbursts in 1958, 1967 and 1985, it is reported as mag...
Got up early this morning to catch my first glimpse of this famous recurrent Nova and I also managed to find a gap in the clouds to take a spectrum showing an...

Well noted Robin - OIII emission can become prominent on decline - my best example is N Aql 1999[2] at http://www.astroman.fsnet.co.uk/naql2p2.htm best Nytecam...
... Oh yes... That should make a nice colour shift in the eyepiece if it is still bright enough. I must admit, I am struggling to see any red, It looks mainly...

Hi Robin - seem to have lost your regular email address - hope this reaches you. Have defocused, boosted colour saturation and labeled stars as attached....
Hi Robin - another attached. Colours don't hold up with very bright or faint stars. Maurice ... Email sent from www.ntlworld.com Virus-checked using McAfee(R)...
Hi Maurice, robin_astro at hotmail dot com will find me I am quite impressed the colours hold up as well as they do. The filters are not exactly photometric...

Dear all Our school Star analyser arrived yesterday & it's now safely installed in the filter wheel at school. This evening's weather started out promising at...
