    Default M13 sketch from last night



    I've been dabbling a little with sketching over the last few clear-ish nights, and decided to have a 'proper' go at M13 last night

    Spent over an hour on it, in the wee small hours last night (1am untl a bit after 2) - to the point where I was just about bog-eyed - LOL
    Sky starting to haze over as I was doing the field stars, but just about held-up long enough for me.
    Was up and out early this morning n'all, so I'm knackered now - but I think it was worth it though - very happy with it.

    Used the C8, with 13mm Hyperion for the cluster itself - and 25mm SkyWatcher plössl for outlying stars. Neodymium filter in and out half a dozen times

    Drawing scanned, then 'greyscaled', flipped L/R (cos I used a diagonal), inverted to white on black, then brightness/contrast tweaked a bit in PaintShop pro

    re-sized to fit the forum

    Oh, and in a true imager styleeee
    Equipment used.... Staedtler 2B and 3B pencils, on Tesco own brand 'Finest' A4 copy paper


    And on a side-note.....
    While I was in the area, bagged myself the little nearby galaxy ngc6207 visually.
    13mm Hyperion with extension ring, at 9.6mm, only just visible with averted vision as a very faint smear, with a stellar-looking core.

    Haven't done much 'astro' sketching, there's 3 others in my gallery, but they were all done in a rush, on a freezing cold night - this was my first serious attempt at an accurate astro-sketch.

    I'm no stranger to sketching though - I used to do a LOT of pencil sketching some years ago - and after attempting M13, I've found that clusters really do lend themselves to realistic sketches, much better than the galaxies I previously tried.

    I could see myself getting 'into' cluster sketching

    That is an impressive sketch, Carlos. Astronomy picture book quality.

    Hi Jazza

    It wasn't 'Photoshopped' as such.... But it did need to go through a few steps in an image editing program, in order to get from original drawing to the image above.
    I use 'Paintshop pro' rather than 'Photoshop' or 'M$paint' - but they all do pretty much the same thing.


    Here's a photo of the original drawing, in pencil, on white paper.



    I scanned that picture - then because my clunky old scanner introduces colour-fringing when you have lines or dots close together, I changed the scan to 'Greyscale' to get rid of those colours.
    Next I flipped the image left/right - to counteract the fact that my diagonal flips the image left/right.
    Then I inverted the image to a 'negative' - to give white stars on a black background.
    Last of all, adjusted brightness and contrast a bit.
    Nothing added to (apart from the text), or removed from the picture, the bright/cont. tweak was just to get the shades of grey looking about the same as what I could see in the eyepiece.

    Absolutely fantastic, Carlos!

    *Quick question for you:

    In previous posts [e.g., Sombrero Galaxy finder help], you have text and graphics added to some Starry Night still shots--what program did you use to construct those?

    I have a Mac running OSX ver 10.4.11 and also have Starry Night Special Edition. I have looked into free online photo editors that are Mac compatible such as SeaShore---but it is not very intuitive how to add the graphic and text layers.

    Hi Mark
    I use 'PaintShop pro' for all my image editing.

    In PSP there's a handy text tool, and one that does lines and arrows - both very quick and easy to use.

    Like this...



    Select the text tool, click on the image, then type the text into the box.
    Text will be the colour selected in the palette, and you can play with fonts, sizes etc, just out of shot to the left on that upper toolbar.

    Lines and arrows are similar - the tool is next to the text tool
    And there's a drop-down menu with many different kinds of lines, dotted lnes, arrows, etc...



    After applying text/arrows, etc - I simply 'merge all' layers before saving the image.


    Sorry - but I'm not familiar with Mac software, but I'd be surprised if there isn't something available which works in a similar way.

    That's really cool; sketches are something I am going to have to work on.
