  1. Hi Craig, I do white on black (lunar) sketching, and use either white pastel pencil or white Conté sticks (or a combination of both) on black Canford paper. All of these should be readily available from any good art supplier. Personally I like to use a red light to illuminate my sketchpad when working on black paper - if I sketch with graphite (pencil) on white paper then I use white light. You might be interested in this new volume from Springer which should be available for browsing on the Springer stand at Astrofest: Sketching the Moon: An Astronomical Artist's Guide (Patrick Moore's Practical Astronomy Series): Amazon.co.uk: Richard Handy, Deirdre Kelleghan, Thomas McCague, Erika Rix, Sally Russell: 9781461409403: Books There are many white on black worked examples in this book
  2. An interesting juxtaposition indeed! Awesome image, but an intriguing joint capture too, congrats on the spaceweather page.
  3. I have dabbled at sketching Mars (and Jupiter to a lesser extent) for a number of years, and have found that what works best for me is to do a graphite sketch at the eyepiece, then to make a colour sketch from the monochrome version as soon as possible afterwards (before I forget what the colours were!) I use a range of coloured pencils and build up 'mixed' colours on the sketch itself by adding very light layers of individual colours with a gentle scribbling motion. Here are a couple of drawings to show the results. I used standard colour pencils from a range of manufacturers - they were just pencils that I'd had kicking around for years! I use a deep red (like Alizarin crimson), a light brown (similar to raw sienna), a pure purple (violet?), pale blue (somewhat like a Cerulean blue), a deeper blue (Ultramarine), orange (similar to Cadmium orange), and a deep green (I haven't a name for this one as I tend to mix my greens when using watercolour). Sketch dates/times are: 2008_01_16, 19:30-20:05 UT 2008_01_16, 22:15-22:40 UT Both sketches have been electronically flipped to correct orientation. Hope this helps. All the best,
  4. Another really good Apollo astronauts read is 'Moondust: In Search of the Men Who Fell to Earth', by Andrew Smith.
  5. Wow! That's an astonishing sketch, very well done
  6. That's a great sketch - very delicately rendered. It hadn't occurred to me that the SN in M51 would be a visual target - you must have wonderful dark skies
  7. Great report - what a wonderful experience, and a superb (and very unusual) sketch. No wonder you are pleased with your new scope!
  8. That's really cool Eddie - well done! :)
  9. Hi Chris, My pencil sketches are generally pretty small too - there's nothing wrong with a 50p sized sketch If you fancy having a go at white on black sketching but would prefer to keep it small, then try watercolour pencil on black paper (black Canford paper is very good for this). Compared to ordinary coloured pencils, watercolour pencils are much softer and non-greasy, so they transfer onto the paper really well (and make nice strong marks), and yet they don't smear easily.
  10. Hi Chris, it's great to hear that you are giving lunar sketching a go The Moon can be a tad overwhelming when you first try your hand at sketching it, at least that was what I found, but it does get easier with perseverance. Top tip is - don't try and draw too big an area at first. A simple, isolated crater will be kinder to you than an intricate stack of overlapping craters in the southern highlands, no matter how alluring they are in your eyepiece! I find the white on black method is kinder than graphite on white, as the shadows are already in place (as Eddie said), and the sketch comes together more quickly. Have a go at sketching from photos too - it's a great way to learn without fighting with a wobbly atmosphere, juggling with clipboards and lights and dropping pencils on your lawn Good luck!
  11. Have you tried Stellarium It's free planetarium software so should include Moon data for your own location once you've set your coordinates. Another very good Moon resource which will give you phases and much, much more is the Virtual Moon Atlas - also a free download. en:start [Virtual Moon Atlas] If you have an iPhone/iPod touch then there are some good moonrise apps available, either free or very cheap. Hope this helps
  12. Thanks Eddie I love the white on black sketching technique for lunar work. I only came across it a few years ago when I saw an amazing LPOD (Lunar Photo Of the Day) sketch, and later tried it out for myself. I find that I have to work on quite a big scale (usually A3) to capture fine detail.
  13. Thanks for such a warm welcome - what a friendly place this is I've just posted a lunar sketch in the 'sketches & unconventional' forum - hope you like it! Thanks again
  14. Hi Folks, This is a Conte crayon and pastel sketch on black paper, drawn at the eyepiece. Sketch is a mirror-image as I was using a refractor with diagonal (07/04/2011, 19:50-20:20UT, ~160x). Clear skies
  15. Thanks everyone for your kind welcome messages
  16. Hello Everyone. My interest in astronomy goes back a number of years, my passion being visual astronomy and astro-sketching. Favorite targets are the Moon and Sun (white light and H-alpha), but I also enjoy sketching Mars when it drops by for a few months every so often (and Jupiter too). I've been reading and enjoying the forums here for a while, and thought it was about time I joined in, so.......hi!
  17. Oops - my mistake! I guess watercolour and dilute India ink can look pretty similar. It's a very effective way to define the terminator
  18. Superb images. I saw that crescent briefly with naked eye and with binos. I particularly like your first image of the Moon in the palest sky

    Superb! Really interesting technique.
  20. That's an excellent sketch of a really complex region. What medium did you use? It looks like graphite and ink - nice to see someone using ink
  21. Great sketch! I like the way you've captured the drama of the grazing illumination
