  2. Hi Dave, Wot Peter said. He's the professional. I am the bumbling amateur. Most of my stuff is built from scrap metal. Here is a random selection showing my home made equatorial mounting with 50mm shafts. The other mounting is my old Fullerscopes MkIV with 1.25" stainless steel shafts. My blog has images scattered throughout of my various telescope projects. The massive, mobile pier under the MkIV was to cope with our high hedges and trees. It is very unsafe to push around due to its high CofG. The dome is 3m diameter, self made from plywood and mounted on a hexagonal b

  4. I was stuck in Sweden so missed all the fun earlier in the week but the forecast was good till the end of the week and for once wasn’t too far off- had a lovely few hours last night when i got back apart from the wet hazy freezing air- too cold to sketch but really good seeing and the first time i’ve really been able to differentiate the general darker nature of the Southern hemisphere compared to the North! Tonight was great too- I didn’t get out till midnight but by then the sky was clear and the jetstream forecast was favourable. But boy has Mars got its skates on! Much lower than what

  7. I've not had my telescope very long. I got it for my wife and I for our 31st wedding anniversary back in July and the first thing we looked at was a star 31 light years away... so the light hitting our eyes was from the day we got married. It was a lovely moment. Since then I think I've had a WOW moment almost every time I've pointed the scope at the sky... it's all so new and amazing. Loving it!

  9. Yesterday I got just a shade over an hour's worth of data on the Crescent, taken from my Bortle 5 back garden, using a Meade SN6 6" F/5 Schmidt-Newton, with ASI183MC camera and an Optolong L-eNhance filter Followed by about 1h 36 minutes of data on the Crab Stacked and stretched in APP, some final curve tweaks and crops in Gimp. Noisy, of course, but pretty pleased at my first effort. Should be able to add more data tonight

  10. Really pleased that it has stayed clear today so I could catch this fantastic sunspot group! Must be the biggest for at least 3 years. Picture taken with TEC140 and Baader Herschel Wedge, camera is Altair GPcam3 290m. Best 4% of around 4000 frames captured and processed with Autostakkert 3 and colourised in Microsoft photo. Thanks for looking.

  18. First planetary image of any sort actually! So this has been a bit of a learning experience! I seemed to just blindly stumble through the programs I used, if anyone has any tips or guides for capturing or processing I'd be delighted to hear them! The one thing I do know is that I am using equipment that isn't ideal! However I thought I would have a crack and see what happened. I will admit that I am absolutely delighted by my modest results.

  20. It's taken a little while, but I finally got enough data this week to "finish" (is it ever?) my Heart and Soul image. It's a 2 panel mosaic taken with the SharpStar 61 EDPH MkII and my ASI1600MM 49x300s Ha, 48x300s OIII and 49x300s of SII, so each panel is about 2.5 hours of data across the filters. The moon wasn't particularly forgiving to the data, so I might add more at some point and see if I can sort some of the gradient issues. Stacked in APP and light processing in PI.

  21. I had an enjoyable couple of hours yesterday evening at Swavesey Priory on the edge of the Cambridgeshire Fens. Swavesey lies exactly on the Greenwich Meridian, so I switched hemispheres a few times. A gorgeous bright, long Taurid fell just to the upper left of the Plough as I was taking the static shots, but unfortunately it seems to have done so during the interval between each frame - d'oh! Would love any constructive thoughts and comments - still new to this so any pointers are helpful. Details at the bottom. Star trails: 16x180s exposures ISO200 on Canon

  22. This beauty arrived in the post on a cloudless day! Who would have thought it. Star test on Vega was almost flawless. Nice even energy across the diffraction pattern both sides of focus and not a trace of false colour that I could see. Always been a dream of mine to own a decent sized refractor like this. Needless to say, I'm delighted!

  26. It's a little known fact that Rusted and myself are clones, although he is a later version. So much of our experiences and current activities are mirrored, we are both DIY'ers, build our own telescopes, mounts and observatories. My 8.5" F12 refractor and mount are built from whatever was to hand at the time, my OTA was made by joining two undrilled 8" Newtonian tubes supplied by OOUK. The mount is on top of a concrete block pier. Before retiring, making folded refractors was part of my business resulting in over a dozen including several 8" F20 to F25. As Rusted says, they can be tricky t

  29. Hi All, This is my first post, but I felt compelled to pen my thoughts on the Lunt LS50 b600 that I bought a few weeks ago (to Help me get thru another Covid lockdown). A couple of important points first. I have been a night time astronomer for well over 10 years, but never tried Solar before. The other point is that I am strictly visual only. Tried astrophotography and hated it. I read quite a few useful threads before choosing the LS50. I wanted something half decent, but did not want to spend too much money because unlike night astronomy there is only one thing to look at. I find

  30. Hello, Here is a drawing I did through a 4" F/8 refractor, seeing was poor and the drawing took 30 minutes to do with detail levels constantly changing. Started drawing at 20:30 at x217 The disk is starting to look smaller now and the south polar ice cap is tiny. Syrtis Major was the main feature on the following side of Mars with the light coloured Hellas region just below it. Dew on the preceding limb was evident as was a small amount at the north pole.

  32. Since moving to France a couple of years ago, telescopes had been mothballed and work renovating our house had kept me away from looking further than the damaged chimney pots and guttering. Anyway, that’s all fine and the telescopes came out again, but not before noticing dust and fungus growing on the mirrors and objectives. ( Meade LX90 ACF and Celestron Evo 6) So, they’re all cleaned up ( pretty simple job once you pluck up the courage) and just waiting for skies to clear. Luckily, we have very dark skies here with incredible views so haven’t missed the scopes too much.

  33. Well, I've been playing with my Mars video clips and here's a first light result. I'm not a planetary imager by any means but thought I'd have a go. It's not the best, but I got to video 4 and thought I'll be here for days trying to get the best, they're probably all very similar! I used a ZWO 178MC, Televue 2.5x powermate and firecapture to capture the frames, followed by autostakkert, PI and a bit of lightroom. The conditions weren't great - put it this way, I wouldn't have bothered trying to do some DSO work, it wasn't that kind of night. Anyway, pleased I sup

  34. 31st May 2003: Arrived at the Butt of Lewis Lighthouse, the northern most point of the Western Isles (Out Hebrides), at 03:00 to await Sunrise and the only Annual Eclipse I'm going to see in my lifetime in the UK. As the time of the eclipse approached, all assembled looked at the cloud and though "this isn't looking good!". Then the clouds parted enough to reveal this: I didn't know whether to watch the event or photograph it. Luckily I did both so I have the memory and the images to remind me.

  36. Is everyone over Heart and Soul yet? I always get a late start on targets due to my limited visible patch of sky. I have to wait until objects are high enough above the house to see, at which point, everyone else has already imaged them. I find I'm having difficulty processing images from the QHY247C camera and I don't know if it's an OSC issue, if it's this specific camera or something else in the imaging train like the filter causing it. I'm used to mono imaging and the background of a stacked and color combined imaged being mottled RGB splotches, so it's no surprise to find a colored backgr

  37. I've been playing around with the Edge in the garden during these last few clear nights during our lockdown. Not the usual dark site (SQM 19,3 here) so I thought I'd pick some brighter targets, and these just might be perfect for that. Enjoy!

  38. With the direct experience of owning a 7" f/12 I suggest that the cardboard tube was no lightweight. I have grave doubts that the cardboard tube of the 12" was remotely stiff enough. I laminated a 12"Ø cardboard tube from commercial concrete piling tubes in 1/4" thickness. It was only 2m long but sagged overnight between end supports and constantly went out of round. My own variations on a theme of tubing materials all weigh much the same as each other. Thin steel/thicker aluminium/thicker cardboard/PVC/plywood rings and tubes or dowels. Even CF and modern Tufnol! I finally set

  40. I've recently acquired some old (1969) copies of Sky & Telescope magazine, and this scope was on the front cover of the March 1969 issue. As it's such an old issue, I hope I'm not infringing any copyright rules by copying the accompanying article here, for our members interest, with full acknowledgement to Sky and Telescope as the original source over 50 years ago. If I have that wrong, my apologies and Mods please delete this post. The scope just made my jaw drop, being a home built (apart from the objective) 12" F16 achromat.

  41. 5.00 - 6.00am Saturday, cold, clear, Moon high near south (waning gibbous, near third quarter) - Bresser Dob in action, easy to use with the Moon so high. Orion ducking below trees to west. Rupes Recta, the Straight Wall (a long scarp) in Mare Nubium was very evident - a bright line. But Clavius to the south, and also close to the terminator, looked very attractive. Such detail! - Porter and Rutherfurd (with their peaks) and two smaller craters in the wall of Clavius, the arc of four in decreasing sizes across the crater floor, and a great many smaller pits all stood out nicely at x212

  44. I think John put his finger on it at the start when when he said, 'there are recommendations in there regarding the minimum aperture telescopes that are considered "useful" (whatever that means) for astronomy.' A lot of these books were rooted in amateur astronomers contributing to professional astronomy, very much a Patrick Moore thing. However, SPM was also a great advocate of the binocular. So if the 50mm binocular is worth having, why would the 50mm telescope not be? In a nutshell, if you are not doing science, but just enjoying the night, you can enjoy whatever you like. The only ins

Through a scope for the first time it is a game changer to how you see where your feet are planted and on what they stand. Marv

  46. I had a fascination for space right from when I was a small child, and was given a telescope of the 'serious looking, but really a toy' variety for Xmas . I recall which particular house window I was looking through with it , and we moved away from that home when I was seven, so I must have been that age or younger when I looked at the Moon magnified for the first time. Over half a century on, and that remains as a moment of awe burnt into my memory. Second major thing was the Apollo program. I still have the scrapbooks I enthusiastically kept from Apollo 11 to 17. Dad woke me up to come

  48. Hi Rusted, Thanks for your fascinating insight into the challenges that building such a Behemoth presents: you clearly have extensive experience of these challenges! All joking aside, and as a lifelong refractor fan, (including long focus achromats, on which I cut my teeth, so to speak, hence my F15RULES handle), I totally see that for anything much over 6"/150mm aperture, reflectors of whatever type are much more practical for amateurs to own and use regularly. Given the practical issues, especially of mounting, associated with such large tubes, you can perhaps see why the own
