  1. Hi, Just thought id post this up as I was very very! Surprised at what can be achived with a £40 secondhand telescope and then holding my phone up to the eyepiece..... lol I did mess about with the camera settings and I then edited the picture on my phone basically sharpened it a little bit etc jus with an app.....
  2. I have loved astronomy, space and everything related to it for years. Looking at objects in space has often been a challenge, but the rewards are countless. It is always a pleasure looking through the eyepiece and being astounded by what I see, but my greatest pleasure has always been sharing that view. Taking photos and publishing them, is great way of sharing what's up there, getting people thinking about the wider universe we inhabit. It my experience, it's even greater to set the scope up, and then get a friend, neighbour, anyone to look through that eyepiece for themselves, the reaction is often of disbelief, surprise and suddenly for them it seems to click as to why I am constantly going on about space, my telescope and how epic it all is. Just over a year ago, I heard of something called the Virtual Star Party. Thanks to the power of Google+ and Google Hangouts, amateur and professional astronomers are able to stream a live view of what they are looking at through their telescope, to the internet and thus an audience around the world. Having watched several of these hangouts; I quickly realised I wanted to be part of this, to share my passion for astronomy and my view on the universe. This was to me, the ultimate way of sharing. Of course, it's never that simple. I am a bar man, so I work irregular hours, with a changing shift pattern, the weather in England never plays ball and technology can be a fickle thing. The Virtual Star Party is hosted and co-ordinated in America, so time difference, light summer skies and shift patterns normally conspire against me, but this Monday - the 23rd of September 2013 at 4:00 GMT, I was drinking coffee and joining the Virtual Star Party for the first time. Technology was against us, with fellow amateur astronomers suffering from computer issues, communication issues and in my case, the microphone on my webcam dropped out. Gremlins aside, the show went on and for just under an hour we broadcast our view, live to an audience around the world, that hour went fast, and it was fantastic! I will be the first to admit, I was nervous and really didn't know what to do with myself, something that given the chance I want to work on and prepare for a bit next time. Thankfully my seeing was really good that night, my scopes usual gremlins weren't playing up and the sky was crystal clear with no wind present. I opened with my view of Jupiter, it's bands and soft hues showing up wonderfully, the audience would easily be able to tell it's live, given the atmospheric turbulence made it shimmer, and shift, but not so much as to ruin the view. Thanks to my new camera, the ASI120mc and the wonderful FireCapture 2.3 software, I have great exposure control, so could increase and decrease exposure easily and precisely, allowing me to show the four major Galilean moons. As the show went on, I moved over to my view of the Moon, a combination of good seeing and the new HD mode that Google Hangouts delivers, enabled me to really show off the craters, shadows, mountains, surface texture changes and really just enjoy what remains one of my favourite objects to just sit and stare at, for hours and hours! Indeed, this view and the kind commentary from the other astronomers, really helped settle my nerves and just relax and enjoy the moment. The audience seemed to be enjoying the view, asking questions and that really was a pleasure, knowing other people can enjoy what my backyard view has to offer. This technology, this ability to share, with reasonable ease; a view of the solar system and beyond, from a backyard in the middle of suburbia, is in my mind, remarkable and of huge benefit. Rarely people look up, those that do, will spot the Moon, a few stars and wonder as I think most people have, what is out there. Here, with this technology, we can share, explain, with detail and laughs along the way. As the show wrapped up, I moved back to Jupiter - and just as goodbyes where to be said, I spotted the leading edge of the Great Red Spot, something the Virtual Star Party had never seen before, due to timing and other conditions. So there I am frantically trying to get my focus spot on, whilst Fraser and the other astronomers try to spot it. Ultimately we couldn't tell if it was there, or not. So after the show ended, I captured some footage, and stacked it; it was there, the GRS! By this point, it's gone 5:00 in the morning, my fingers are cold, the telescope dripping wet with dew, but the mix of geeky excitement and coffee let me stay up for another hour, to capture for the first time ever , a view of Mars. The sleep deprivation made my shift at work a little bit painful, but I am so glad I finally got to take part in this amazing event, made possible with technology, but passionate, enthusiastic and likeminded people. It was an absolute privilege to do it, and one I hope to repeat often and soon, well assuming those clouds keep away! Images attached where all taken using the following setup: Meade LX90 8" SCT ASI120mc Camera 3x Meade Shorty Barlow for close ups Processed with PIPP, Registax and Photoshop.
  3. Hi all, I captured around 4000 frames in liveview mode while shooting at the Moon, with Camera / 2xBarlow / Telescope. Then cropped them in PIPP and created an AVI file to export after to Registax. The video file, even after cropped and centered, is not very stable (i guess because it was windy?), u can see the Moon is misplaced in a few frames, but nothing really serious, in my guessing. So, when i pass it to Registax 6, i do the normal process that i already did for saturn and for full lunar disc, (Align, choose a decent amount of align points, limit to 95% quality or best frames, etc). Thing is, the final result is something really odd, with the Moon not even entering the final pic. Somewhere along the alignment points process there is a problem that i dont have the knowledge to solve, and you can see the green lines of alignment going way out of the picture for some reason. I only had time to printscreen one shot before coming to work, and looks like this: Some alignment details were, as i remember: default minimum number of pix between alignment points - 30 from edge - 20 chose around 100 alignment points automatically (in some cases, there was one in a black area, but i tried right clicking in order to delete it,but it wouldnt do anything) So, i wonder if i could get any help from you guys! Would be much appreciated. Thanks, Rui
  4. sct 9.25,mono dnk 21, pier mounted c gem average 1000 frames @60fps,stacked with registax 5 average of 600 frames stacked
  5. after setting up the scope to cool and getting the long johns on i ventured into the back garden to find a pretty poor sky ,which got worse rather quickly. my only shot of anything was the moon and jupiter. i pushed up the eyepiece to x150 and slowly observed along the terminator. have to say i really enjoyed it. with little white peaks sticking out through the shadows. i came across an area where the shadows and peaks made for amazing viewing. i looked it up after and found it was the area of the rupes recta fault and "thebit" . i can now see why observing close to the terminator is so worth while. it gives some 3d like views . i then sat and observed jupiter,and this is my question. am i right in saying that the dark spot tonight on jupiters surface was io's shadow ? or have i got that wrong ? visibilty was getting bad and there was a huge glow around jupiter ,and the view kept jumping from average to a fuzzy blur. but i sketched the pic above out. as i think i wascorrect in assuming that was the shadow of io. clear skies (yeah,right !)
  6. The awful seeing conditions continue where I am but I at least managed to get this in between the clouds last night: Details: Tasco 302012 114mm reflector telescope. Afocal through 40mm wide angle EP with Canon HF100 Camcorder. 9 Second movie clip at 1080p 60fps stacked in Registax 6 and processed in Photoshop CS3
  7. Lovely dawn this morning. Full Resolution image, with "mouseover" label option, at: http://astunit.com/tonkinsastro/planets/20121211_planets.htm
  8. First use of the new pier. Since the moon was out, I shot it! Celestron Nexstar 4SE (mak, 1325mm focal length, f/13) on EQ6. Camera DMK41. Processing: AS!2 stacking. Wavelets in Registax 5. Panorama in Photoshop Elements. I ended up taking 13 panels of over 1000 frames each with generous overlap to cover the whole surface. Wanted to make sure I didn't have a repeat of the disaster last time. Again I took a conservative wavelets and levels approach. I really wish this was in colour, but having to manually process each of the 13 files by hand, I don't fancy needing to do that 3x over! All of a sudden a planetary OSC sounds more tempting... Tried to take a flat using a white plastic bag over the scope still pointed at the moon, but it came out funny so I binned it. I think it was too far into the noise floor to be useful.
  9. Seized the opportunity offered by a break in the cloud to get my 1st imaging session in a very long time in. A bit rusty, so went for some Lunar imaging.... not entirely sure of the name of some of the features... Bailey (background) and Tycho (foreground) ? Hevelius (?) with 2.5x powermate - a bit fuzzy: No idea what this is - wasn't paying attention: Have to say, imaging the moon is a lot of fun. And when not capturing the preview screen makes you feel like you're flying over the moon! Awesome Have fun
  10. Here's some F30 mosaics from this mornings session at.. some ridiculous hour that not many people know exists. F30 is as far as I can push my scope using my Televue 3x barlow. Its not often the seeing is good enough to make it happen using only an 8 inch aperture scope either. All shot through a red filter. Can't do much more to reduce the noise in these when working at this focal length, its a by product of the lack of aperture. First up is a 6 pane mosaic of Moretus Followed by a 13 pane mosaic of Plato and surrounding region And then a 5 pane mosaic of Copernicus and finally a quick shot of Tycho
  11. As the clouds have come in thick and fast and lunar imaging has gone the way of the dodo for now I decided to look at some previous shots I've taken of one of my favourite targets, crater Moretus. I realised I have enough to shots to really show how libration affects this crater and the lunar limb. This is the result:
  12. Thought was in for a good night tonight, walked out not a cloud in the sky, yippee. Dashed in and quickly set up camera, telescope an tripod and aimed at the moon. Rattled off 10 shots on continuous and went inside to check focus. 5 minutes later not a star, moon, planet, light anywhere, TOTAL CLOUD. Where did it come from? Anyway I will share what I managed to get in case you were less fortunate.
  13. Hi all just a few from last night full boil most of night here managed to get a few good ones heres the details C9.25 pier mounted c gem Dmk 21 mono ir/uv filter all are 1000 frames taken,300 average stack ic capture gain 370 expo 1.130 gamma 90 fps 30

    70% LRGB moon

    From the album: Lunar

    An LRGB image of a 70% illuminated moon. Taken with my Esprit 150 and Trius 814. At this level of illumination the image just fitted my field of view. After calibration in CCDstack, I selected the clearest images and aligned these in RegiStar. After stacking/error rejection in CCDstack, I then followed my normal DSO post processing (a mixture of PI and PS) with the exception that I used PS autocolor for the initial colour balance.
  17. From the album: Astronomical Objects

    I have a friend that likes to take pictures. This was done using his Canon T1i Rebel DSLR.
  18. From the album: Moon, planets and single stars

    First try at video stacking on the moon with the 130PDS. Also 1st try at saturating colors in post-pro, rather than bicolor imaging. I find the result show nice color variations in the "seas". Gear: Olympus E-PL6 with Skywatcher 130PDS on Celestron Nexstar SLT. Capture: FullHD 30p crop movie, don't remember the other settings. Processing: cvastroalign, fotoxx Date and location: 2017-08-14, near country 50km from Paris (France)
