  1. Here it is next to my trusty 130SLT. As you can see, it's somewhat larger! It's shoulder height on me (although I'm not the tallest of chaps, 173cm) I had an idea to observe and sketch every Messier object over the course of however long it would take. Is that something people would find interesting?
  2. I'm hoping the extra aperture will bring out more details in the deep sky objects than my 130mm newt.
  3. I am now the owner of a brand new Skywatcher 250P 10" Dobsonian! After spending a while building it, collimating it and marvelling in its splendour, I got sad at the fact that there's nothing but clouds in the sky. Still, someday soon, you can expect some DSO sketches. Thanks to the kind folk at Tring Astro for their help and advice.
  4. Phillips guide to the night sky is good for 'target of the month' ideas and is published every year. this, combined with stellarium is generally what I use.
  5. Just to add the the great suggestions here, try looking at Mizar and Alcor in Ursa Major, then upping the power and splitting Mizar. you could also aim for Eta Cassiopeia for another nice double. The double cluster in Perseus is one of my favorite things to look at in the sky, go in on low power and see how many stars you can count.
  6. I use these things for my 130SLT : https://www.amazon.co.uk/dp/B01IN4E4BA/ref=cm_sw_r_cp_apa_i_qW.sDbR3M06JC they're Lithium ion, but AA sized, and each has an individual charging port, so you plug them into the supplied 4 way micro-USB cable, stick em in a USB port and then let them charge. usually lasts me a couple of nights before I have to recharge them.
  7. See if your phone has an "advanced camera" setting where you can adjust the exposure time/ISO settings etc. If you reduce the glare you may well get a clearer image, and if possible turn autofocus off and set the manual focus to infinity

    All free hand, although I used Gimp to invert the image and added colouration to the main stars. Computer was only used to adjust colours, not to add any detail.
  9. Looks great and I'm sure the photograph does not do the view justice. When you get tired of planets, or just fancy something different, why not try pointing the scope at some double stars? I always find it a wonderful experience to discover that stars you thought were single points of light with your bare eyes split into two or more when you look through a telescope. Albireo is a favourite of mine, but also check out Epsilon Lyrae and Mizar.

    Double Cluster

    Thanks, I had fun with this one. Very difficult sketching at the eyepiece but I was pleased with how it turned out.

    Double Cluster

    Second attempt at a sketch. Skies were clearer for this one.

    This was my first attempt at a sketch. Was battling clouds the whole time, so that added to the challenge. Let me know what you think.
  13. Also to further my collimation obsession I received a Cheshire in the post today. I've used it and collimated my mirrors (previously I was using a laser collimator but I thought I'd try it this way too). After collimating with the cheshire I tested with the laser and found that everything was in order. Guess the real test will be tonight.
  14. I shall add to the list. Weather looks good for tonight too...
  15. Last night finally gave some clear skies to observe from my back garden. I'm lucky enough to live in an area with low light pollution and so DSOs are something I like to observe (even though my 130mm aperture doesn't always like them). I also had a mission for myself last night - ignore the go-to function of my scope and find the targets manually. I still set the alignment up as usual as a fall back, but I've found that when I slew to targets near zenith with the NexStar SLT the tube can hit the legs of the tripod and mess up the alignment. After aligning and checking the focus (I've been
