    Went out this afternoon and had a good look at the area to determine where to put the new "pond" and fountain/water-feature. There's a wide view through the picture window in the living room so decided to put it away from the other pond and bird feeder between the new micro observatory and main one. Started a bit of planting round the naturalistic pond too. Some photos from indoors as it's raining.

    I tend to agree with you re: the aluminum tripod being a really weak link. I had an EQ3-2 mount once that was fitted with an HEQ5 tripod (1.75" steel tubed) and it was like a different mount altogether. It carried a 120mm F/8.3 refractor well for visual observing whereas it was jelly-like with the alu tripod. A nice hardwood tripod is even better but I guess it's too much to expect mass-production mounts to be supplied with those !

    Thanks, Ken. Let me know how you get along. I think I'll pop up on the roof tonight, the first time in over two weeks!

    I expect to be adding to this blog shortly as I shall be building a new astro imaging control system from scratch and including installing 3rd party drivers and editing the source code to alter and/or add features. I have a spare Raspberry Pi 3B and an 8GB micro SD card. For setting up I have a spare keyboard, trackball and a small TV set I can use as a monitor using HDMI.

    If you put frogs or fish watch out for wild life stealing them, cats for sure, raccoons or skunks if you have them?

    I've designed and now printing a fountain head which should produce a sort of doughnut shape hopefully with a smooth surface. We'll see. Here are the top part diagrams. This forms a ring where the water comes out with an outwards tilt. The inner part will be held further down with a ring with slots in for the water to pass through. A further tube will connect to the pump. All parts in ABS and will be solvent welded together.

    WOW! That is some pond ? I don't envisage digging anything like that!!

    Adjusted offset and focus but the field doesn't seem flat. This could do with improving - if only I could think how!! Making some progress in other directions though ie. Dew heater and camera cooler. To show the benefit of the cooler I need a dark night - no moon!

    The correct focus position was set up using an optimally tuned PST less its 40mm objective. The subsequent mod is a stage2 so the black box is empty. The digonal containing the blocking filter fits in an aperture machined in the rear face of the black box. Spacers have been supplied that make up any difference in the post etalon focus. Any very small adjustments for different eyepieces are by way of the OTA fucuser and lie within the etalon position tolerances.

    Yes, the tilter sits immediately in front of the ASI 174. Normally you'll need around 1000 frames per exposure - this allows AS! to select the best frames for subsequent stacking, then apply Registax wavelets to bring up the image.

    Looking good Gina, is it possible you can add an extra day for the weekend so we can have an extra day off work? ?

    Pardon me for butting in, it sounds like you are tightening the screws right up. You should use the two screw adjusters to move the scope to the right place, while the third, sprung, support stops it from flopping about.

    Very nice read Chris I managed to catch CTA 102 visually as well just before Xmas. Prior to that my most distant object was a "mere" 4.5 billion LY's ! I believe CTA 102 is still around mag 13.

    Almost went for this little one two years back, and got its bigger brother the 130P Flexitube. Skywatcher knows how to make great little grab and go scopes!

    Here are the pictures of the original electrics from the fridge all mounted in a project box. Unlike Ade Swash's very neat mounting of these components ( http://www.swashastro.co.uk/peltier_cooler_box.html ), I chose the simple, but far less elegant solution of mounting the switches and power inputs en masse. It may not be pretty,but it seems to work.

    Further update with progess. I've finished the basic cooler box made out of 1.5mm thick aluminium sheets folded and bolted together to the same design used by Gary Honis. http://dslrmodifications.com/rebelmod450d16c.html I slightly mis-measured (1 mm) and ended up having to file down the edges of the interior heat sink (Doh!)

    Thanks for this. I've been using bins for the last couple of years to try and learn my way around the sky. I originally planned to get an 8" dob (based on the very advice you speak of), but now I'm leaning towards a Nexstar simply because I don't want to maximize viewing time. I like star-hopping with bins and naked eye, but don't want to do that with a scope.

    Bit late commenting, but this was a nice read. Brings back childhood memories; not so good binoculars, fabulous Pleiades... Thanks for sharing. Rune

    I always say this , a goto system is ok but what tends to happen is this you set up and do it's star align and the paper work will say the skies are your oyster that's not always the case ,but when it is ,it's great ,then what happens is you tend to spend a very short time on each target .because you can point at any thing it takes my eyes a good 15 minutes to really start pulling the fine detail out planets and galaxies and the novelty of the goto soon wears thin after a while I love to star hop I really do it took me a good 15 months to learn all the goodies that can be seen at the eye piece and the knowledge of knowing where things are is satisfying to say the least , If you loose power or stub your toe on the mount it's a new star align ect Goto is great for some,and not for others the limited viewing nights in the UK make goto a great choice for those that want it and the technology these days is good so if it's what you require go-for it But my dad always said to me "knowledge is power" . when I have friends round I enjoy manually moving the dob mounted newt around ,the thrill of find in the targets is one hell of a feeling and showing other his great .

    Hi Andrew, These dilemmas will perpetuate towards eyepieces once you have a scope, so don't fear the enjoyment is here to stay ! I started with a 10inch dob and love it (1st scope), then I managed to get a secondhand Edmund Scientific Astroscan which is a neat 4.5inch grab and go (2nd scope). I have more than my eye on the 50mm Ha solar scope (3rd scope when its released / 1st frac !). Lastly (and I really mean lastly) I frequently drool over an ivory televue 85 and when time and funds allow plan on this as my last scope. Its obvious each scope has strengths and weakness, these details can / are debated into ever decreasing circles. Different kit excels in different ways for sure & I personally don't get too sucked in to the frac vs newt arm wrestle as a taste of both sides is a clear advantage, however & back to my first scope, have you ever priced up a 10 inch APO? :) http://www.astromart.com/classifieds/details.asp?classified_id=653636 By the way: If you are in Bristol drop me a message as you are welcome to get some hands on views with the 10".

    Matt, very true! To echo your sentiment, it is the possibility of one day being able to possibly provide some meaningful contribution to the repository of human knowledge that got me interested! Regarding your comment on spectroscopy, I attended my first meeting of my local astronomy society (Reading) last night, and we had a talk from one of the lead engineers involved in the mid- infra red instrument, with some (I assume basic) explanation of spectrography. There was also a very friendly member of the society present who is apparently the local authority on the matter! I went from having not really heard of a subject to very interested in it over the course of the evening haha! One thousand times this. I'm treating Astronomy like sport - train with people better than you! Clear skies! Ryan

    Nice report Stu, very similar to the Pronto by the sounds of things, especially the description of the Double Cluster. I am very impressed with the views I get through it. The Pleiades and the Orion Nebula are equally as spectacular and I cant wait to see the cluster in Hercules and the Wild duck cluster later this year. Shaun

    Tested it out last night and initially dissapoinyed that the views aren't as bright as my 15x70 binos then realised that one eye is never as good as two on similar aperture.think I want a slightly zoomier eyepice too as the supplied 23mm at 328mm fl isn't quite enough.nice and light though!!!

    The 200p is is a great scope and sgl is fantastic for debating the pros and cons before buying....... but groucho wouldnt be happy.....didnt he say "PLEASE ACCEPT MY RESIGNATION, I dont want to belong to any club that will accept people like me as a member" : ) Cheers

    Congrats - very nice purchase. That's a cracking little planetary scope which you'll really enjoy. Saturn's due south around 11pm at the moment - but it's low in the atmosphere so you'll need a fairly clear night - avoid over magnifying it cos it'll get "grainy" - enjoy :)

    Nice report, I really like the slippers bit shows commitment. I was in and out the other night in flip flops I use in the house in minus 12, it was only 5-6 mins with the binos at a time. This only shows how stupid I am, I walk past 3 pairs of walking boots on the way. Alan

    Okies.. 16IC - the camera is recognised and starting to get the communications sorted. The pain is to support this camera will require the user to install the FTDI drivers. It would be possible to embed it in the driver framework if the dynamic library path wasn't hard coded (OSX uses full library paths and not a leaf name that's searched). I'll revisit this later and see if I can get it so the user doesn't have todo anything.. Naturally this is slow legacy.. USB1.. etc but it's a good camera and I'd prefer the titan to be imaging at the same time - letting the 16ic guide.

    If you're going for M10 and M12, why not M14 too? It's a magnitude fainter than M10 and M12, but half a magnitude brighter than M71.

    Nicely laid out plan you've got there, I hope I can have a go at some of these too. I'll be interested to hear how you get on with Cats eye nebula in Draco.

    Out of curiosity, what ep/diagonal combination are you most typically using for the Messiers? And is this different from what you use for splitting doubles? I think Albireo is one of the most beautiful objects I have ever had the good fortune to see - the colours are stunning! Look forward to your next post!

    Thanks a million SGL team. I saw many websites, forums upgrade there platform engine. But I never saw anyone who provides such a beautiful tutorial. Its really rare. I see you put a lot of effort on it. Not only screen shots but also labeled by number!
