    WW Psc .. what kind of star is it? It obviusly can't be nor a Wolf Rayet or a Be. Simbad says "Long-period variable star". Striking emission lines.... Here is our attempt with WR 136 : http://www.alexstargazing.net/spectra/20151107_wr136.html You never stop learning in spectroscopy... unfortunately we (me and Marco) had to temporarily stop our spectroscopy activity... looking forward to start this amazing activity again. Which software are you using for processing spectra? (I apologize for my bad English, not my native language - still learning!) Great job! Alex

    Should I buy an H-Beta filter?

    Thanks everybody for your advices!

    Prominence in H alpha

    Your sketches made me remind of those made by the pioneering Pietro Tacchini (1838-1905) (here). Your drawings are artworks. I'm following you!

    Thanks Gu... You know - I'm stubborn

    Should I buy an H-Beta filter?

    Not my first.. I already have OIII filters I regularly use on nebulae... Thanks for the link! I'll read it carefully... Wonderful reference!
  11. (I'm posting in the eyepiece section, can't find the right one) Hello everyone, I have a question on H-beta filters, because I'd like to observe nebulae as the Horsehead Nebula.... but other amateur astronomers advised me against doing that. I own a f/6 200 mm (~8 inches) Dobson telescope and the set of eyepieces shown here: They told me I could not use it at its best, because (if I remember right), my telescope is too small. And in case of buying one of these, 2" or 1.25"? There are diffuse nebulae that are wide... but the Horsehead is tiny instead (8' x 6'). I'm a bit confused... Thanks you in advance for your advices and explanations

    Show me your eyepiece/accessories case, please.

    Hi, this is my little case! I own a f/6 20 cm (~8") Dobsonian telescope. 30 mm: 40X, AFOV 68°, FOV 1.7°, pupil 5 mm 20 mm: 60X, AFOV 70° , FOV 1.16°, pupil 3,35 mm 12 mm: 100X, AFOV 52°, FOV 0.52°, pupil 2 mm 9 mm: 133X, AFOV 52°, FOV 0.39°, pupil 1.5 mm 5 mm (planetary) : 240X, AFOV 60°, FOV 0.25, pupil 0.83 mm There are both the 1.25" and 2" versions of the OIII filter... I use the bigger one to observe large nebulae as the Veil Nebula with the 30mm eyepiece. I used it also with my boyfriend's 38 mm eyepiece. Modest but I think it meets my needs Bye!

    Book suggestion - Your favorite read

    This topic is extremely interesting. Lots of links and suggestions! I read Arthur Koestler's The Sleepwalkers - A History of Man's Changing Vision of the Universe once. It's not an easy book to read, maybe disturbing in some passages... but deeply fascinating. It changes a bit our way of looking at these great figures as Copernicus and Thyco. A book I really LOVE is The Hunt for Planet X - New World and the Fate of Pluto (2009) by Govert Schilling. Written and published before New Horizon. It talks about more recent astronomy... Lots of hidden figures in recent astronomical history. it's worth it. In the first part of the book, Govert narrates the discoveries of Uranus and Neptune, but the real core of the book is that untold, brilliant story of the discovery of Pluto and the other TNOs. Govert investigated it in deep. (I apologize for my bad English - it's not my native language - I'm still learning! ) A few images of our copy:

    Hello from Italy!

    Nice. Okay, I'll definitely do that then! Maybe tomorrow. (And, by the way, "humongous" is a great new word... thanks!)
