  1. Two weeks ago I was imaging the Milky Way in Austria. When processing I found something unique (I think). In four of the images a meteor strike with after that an expanding plasma cloud was clearly visible: Meteorite explosion by Andre van der Hoeven, on FlickrAfter combining the first two images I noticed also a possible breakup event that released a blue plasma cloud and a piece of debris, while also even showing the North America Nebula:Meteorite vaporization detail by Andre van der Hoeven, on Flickr

  2. This started in May, and is set to trundle on for another month yet. I've captured 12.3 hours of luminance so far, which is quite a difficult task here at 51º with as little as a couple of hours darkness a night (and that’s when there’s no moon about!!) I think I’m now ready to move on to the RGB and turn this in to a colour image, which should keep me busy for a little while yet, but I made the decision at the start of summer this was going to take as long as it took, and I wouldn’t move on until I had cracked it. Imaged with the Altair 6” RC and Atik 460 ex & IDAS P2. Captured in SGPro

  4. So here's my latest... Quite chuffed with this one, I'd say it's my best yet. 15 or so (I forget how many) subs, 300s at ISO 1600, darks, flats and bias, equipment as per sig, modded DSLR at prime focus, Pixinsight. It's also the first proper outing for my new AZEQ6GT mount, so I'm well pleased with those small round stars. Small coma still showing in the right hand corners (those are the frame edges), I need to get that nailed down. I've deliberately presented it upside down since I figure it highlights the dynamics of the structure in the cloud rather than leading to debates about whethe

  5. Hi guys here my first LRGB composition for this beautiful subject taken during 3 nights, it needs a bit more integration to reduce noise on the faint dusts, hope you like here you can find the hi-res version http://www.avogadro-observatory.com/ngc-7023-iris-nebula-cepheus

  6. A brief opportunity between T-storms. Had to try out the new stuff. Transparency fairly good, seeing fairly bad Couldn't see North and no time to drift, so just guessed. This led to 90 second limit. 26 x90s ISO 1250 f/5.6 30 darks applied. A moderate crop. Hopefully, I'll get better with processing one day... Anyone wanting to take a crack at this, I'll post the unaltered stack on Dropbox in a few. C&C welcome. Sorry about the green, not intended.

  10. Well the seeing was pretty good for me in my light polluted part of the world a few days back, so it was time to take out my brand new Explore Scientific 305mm (12") Ultra Light Dobsonian and give it a whirl. I started near the zenith with the ring nebula M57, then worked my way semi-randomly around the sky. I am still ticking off my messier list and managed to get a few new ones (for me) off the list. No planets tonight, Saturn is behind the treeline for me now The ES 82° 24mm I bought alongside the scope makes it much easier to get on target first time from the Telrad. I'm really ple

  13. Easily best for me in a long time. I ventured out into my back garden with little hope as the Met forecast showed intermittent cloud cover, however in Colchester from 22:30 till 0:30 the sky was crystal clear. This led to 2hrs of awsome stargazing, first I set my sights on Saturn (this was my first time seeing it), I was that excited I even dragged the missus and son out of bed to have a look lol. It was a little small but could make out the planet and a ring. I then turned to the ring nebule from there to Andromeda galaxy then to M103. Andromeda was pretty much just a grey smudge and M103 I c

  14. I'm going to attempt to image from my patio tonight I've been spoilt by my permanent set up, but am going on holidays next week and so need to remind myself how to use a mobile skywatcher set up (now being on Mesu in the obs). I expect lots of muttering!!! and scrabbling around for cables etc. But hopefully it will mean I'll have all the bits I need next week and will be able to make the most of dark skies in France. Wish me luck... Helen

  16. I will be thinking about how and where to install more sensors when I'm back home, at the moment my head is not quite into this. I need to be calm and away from people (ie: locked up in my man cave for some deep thinking). The wife has even thought about something today, so I've implemented it as it's brilliant!!!! I have installed two block of woods, they must touch the balustrade and one corner of the box must be aligned to a certain tile on the floor. This will allow to sort of re-align the entire box in case someone knock it off its position.

  18. Nope, becuase if you use an R filter for lum then you are losing 2/3rds of your data. The point of a luminance channel is to capture all of the available (visible) wavelengths at the same time and enable you to concentrate your efforts of noise reduction (via stacking), sharpness and detail into one layer. Basically, the L layer is the most important part of your image - so best not to sell it short. Lum = Carries your detail, contrast and cleanliness RGB = Carries the colour, thats all (thats why you can afford to mash it to death with noise reduction in Ps)

  19. Glad to hear it is living up to your expectations Derek. I have finally overcome my OCD for the slightest focusing vibrations by strapping an auto focuser onto mine, so my EVO150 is going no where now

  23. Yes, but there's more. At each partial iteration of luminance over colour you can slightly blur the luminance layer to reduce noise. Flatten it onto the RGB and re-apply the lum at higher opacity and, again boost RGB saturation and give L a slight blur. It is at the last application of Lum, ideally at 100% opacity, that you no longer apply the slight blur and so you restore the full resolution of the L. If you don't apply the slight blur between iterations I can't see what you gain from the iterative approach. That's not to say that you don't gain, it's just to say that I don't get it! As has

I forgot to post but as I was off to bed last night I caught an early Persied falling vertically in line with Emley Moor mast was really bright and a proper stunning sight. Tonight looks fantastic shame I don't have a decent scope to take it all in. I'll have a quick peruse just before putting my head down Damian

  33. So, after a very long wait for my Baader solar observing glasses to arrive I finally received them this week, and today the sun came out! The large sunspot area in the lower left is visible as an indeterminate small blob, a bit like trying to see a faint galaxy or details on Jupiter, but it's definitely visible which is a thrill for me - being able to look at the sun with my own eyes and see some detail on it. Not going to be doing any serious solar observing with these, it's just one of those things that adds to the experience, possibly the ultimate in grab and go solar observing? Now to l

  34. Nice little article Soupy. It only took 20 minutes to load it on my phone lol. Well done, and a great advert for our wonderful society! I have insurance for my camera, so I need to check the policy. Surely, that is accidental damage at it's best! I'm hoping it'll be ok to keep using this week. Hoping to set it up this evening if it's clear. I'll take it in for them to strip and clea next week, and hopefully the insurance will cover it. Just couldn't believe it - I'd rather it hit my head to be honest! Oh well, such is life lol

  36. Before you fiddle with the focuser, remove the clicklock and pushfit adaptor and just screw the reducer onto the focuser tube - its by far the most rigid and reliable method of attaching your imaging train.

  37. The Baader fluid and cloth are certainly the best I know of, but do rember to use a blower first to remove grit and dust. This will minimise the risk of scratching the lens.

  40. So I'm a 2" eyepiece evangelist, the first time I looked through a 32mm 2" Plossl I knew I would never be able to use a 1.25" again without yearning for a larger field lens, greater eye relief, and that spectacular FoV. That being said, it recently occured to me that this 2" eyepiece collection was becoming somewhat unwieldy; the bag holding it all (ranging from a 37mm ex-NATO Konig to the excellent 8mm Ethos) has become heavier than any of my telescopes, and each one is such a unique shape that short of a military bandolier I have no way to safely transport them anywhere. So, after many month

  41. Title says it all; 41 x 5min subs, iso 1600, Nikon D810A, Star 71, Baader 3.5nm Ha, no callibration. Extracted only the Red channel and processed only that one, avoiding noise injection caused by debayer. Advantage of a 36 MP camera is that you still end up with decent resolution following this procedure, one can always drizzle if needed. NGC7000 Ha by Yves, on Flickr

  42. I don't know so much about that, I believe Michael tests them before shipment and I think on mine he made a slight shortening of the truss poles. I also cannot really say too much about shoes for holidays as I have 40 pairs myself and about 7 of them have never seen my feet and now I don't need to dress up so I wonder if they ever will. I will have to wait for them to come back into fashion, one of the problems of platforms. Alan

  43. At a million miles from Earth, the observing spacecraft will be around three quarters of a million miles from the Moon, so it gives quite a nice idea of the relative sizes of the two bodies (although obviously the Moon will appear slightly larger relative to the Earth). The article mentions a similar sequence of images taken in 2008 from a distance of 31 million miles, which I managed to find here: http://earthobservatory.nasa.gov/IOTD/view.php?id=8933 James

  46. I'm thinking you will need at least an 18" scope to make a really striking difference versus the C11 you already have. Having spent big $ (those are the £ we use over here) on a premium ultralight Dob myself, and then spent time and effort engineering the ultralight compromises out of it, I'd suggest: Look for a used "premium" telescope to buy - you'll pay much less than new, and get a much better product than a mass-produced Chinese scopePrioritize great optics - you can fix/improve the structure as needed, but the mirror you have to live with or spend big money to have re-doneGet a "tradit
