  1. It took me a while to process the images taken this weekend: this beautiful weather did come with a price, too many GB to process! These are from Thursday evening: an almost full lunar disk taken with my newest ASI 1600mm. Lower resolution than my other camera, and slower, but very good to get the moon in the field without stiching. The mosaic below, instead, was taken with my ASI 178mm: smaller pixel and smaller sensor, so much higher resolution, and lots more details. Unfortunately there are some stiching artifact, that I hope to remove in a future version. All the shots were taken with my Celestron Nexstar SLT 127, using my Planetary Imager software. More details about the evening in my blog page: http://blog.gulinux.net/en/blog/jupiter-and-moon-06-04-2017
  2. Just looked out to confirm that the clouds were still there and whether I could see the moon close to Jupiter, and caught this view instead. Not the usual halo around the moon, but much further away. OK, so I know what the con-trails are, but is this a moon-bow? Sorry about the truly lousy image snapped on a convenient hand-held bridge camera in auto mode! (must learn how to control manually some time.) AK
  3. Greetings, I thought I'd share with you all this little arty farty collage I made of the moon and some of the planets: Jupiter, Mars and Saturn. All the photos were taken by holding my iPad to my 8inch dob. They were then processed on my iPad and put together on Instagram. Not amazing I know but I was quite chuffed considering my technical limitations. clear skies, Thomas
  4. Who is planning to observe or image during the penumbral eclipse this weekend? https://britastro.org/node/9088 James
  5. So, did I just manage to flukily capture a satellite alongside the moon tonight?? EOS650D, 55-200mm kit zoom @ 200mm, ISO200 Singleshot. Deconvolved, cropped & processed in LightroomCC & PhotoshopCC.
  6. Hi All, Last Friday I pulled out the new scope scope to have a look at the moon. I did the collimation and left it outside for about 2 hours to allow the mirrors to reach equilibrium. The view through it was BRIGHT, and I mean bright, to the point it was not comfortable viewing it with out a CIR Polarizer set to almost its dimmest setting. I could see that the seeing was not the best, it was fluctuating in and out of focus quite severely but I still decided to try to get a few images of the moon. Through the DMK41 and a IRPass685 filter the poor seeing was obvious, it was like looking through water. The attached images are a result if 20% best frames from 2000 frames stacked in Autostakkert 2 and wavelets applied in RegiStax 6, a slight Unsharp mask added in PS. Thanks for looking,
  7. Managed to get a few pics of the moon holding my phone up to the eyepiece and then *attempted* to edit them. I done the editing with a free app I found, Jus not sure if I've over done it. There didnt seem to be much detail at first. I'm quite happy with the outcome considering my kit is very basic. Hoping to try some other eyepieces next time Anyway heres what I think was the best one...
  8. Lovely evening and clear skies. Taken on my Samsung s4 phone and Tal.
  9. These are two images of the moon right after first quarter in October. These are first light for the new ASI290MC. Processed using AS!2 and a little PS. I tried aligning these in PS but did not succeed. I still need to process the raw but the sharpened tiffs from AS came out quite well, I think. If would be most grateful if you have any comments to share :-) R:)
  10. Hello out there: I was hoping to find a few geeks who like to do their own numerical astro-programming, rather than only using the free software found on the Internet. I use PHP for my work, since it can handle massive astronomical computations far beyond the reach of Java script. It seems like doing your own astro-computing from scratch is a fading art, so I'm trying to keep it alive on the Internet. Right now, I'm concentrating on the moon. Not the Jean Meeus moon, but the NASA/JPL DE405 moon, which is much more accurate (theoretically to the nearest second and lunar distance to within ±0.01 km). If you like to study the moon, here are a few examples of the kind of programming I'm referring to above. http://neoprogrammics.com/index/moon/Lunar_Ephemeris_Statistics_Calculator.php This program computes the basic lunar ephemeris statistics and phase for any given moment. http://neoprogrammics.com/current_lunar_phase_4/ This virtual HD lunar telescope is ideal for cloudy nights when the moon is invisible and you still want to explore it anyway. It allows you to virtually view the moon from four sides - left, right, front and far side in HD detail (1500 x 1500 pixel resolution and at any selected relative phase angle from 0 to 360 degrees. Nothing too fancy yet, just an easy way to view the moon in fine detail. I may eventually add North/South polar views in the future - maybe. There's a lot of work involved, but so far the virtual lunar telescope is working out rather well. http://neoprogrammics.com/index/moon/Full_Year_Lunar_Events_Calculator.php This program displays a schedule of all lunar phases, apogees and perigees for any year from 1600 to 2200, adjusted for any time zone. It makes it very easy to find all blue moons, black moons, super-moons and months with 2 apogees or perigees. It takes approximately 8-10 seconds to compute a complete lunar events ephemeris for an entire year. All the programs are written in PHP and the lunar images were rendered by a FREEware rendering package called POV-Ray. The complete source code and graphics resources required to generate all these images or any user-defined custom view, is freely available as well, should anyone have an interest. Any opinions are welcome, especially from those scientifically inclined to do their own personal astro-computing from scratch. If anyone here has a PHP-based web site designed to perform astronomical computations, I'd like to hear from them and perhaps exchange some astronomy programming source code, ideas and tips. I also have PHP programs for computing very accurate ephemerides for the sun, all the planets, Pluto and 15 major asteroids. EXAMPLE: Below is an example output for 2016 from the Full Year Lunar Events Calculator program mentioned above. ******************************************************************************* BASIC LUNAR EVENTS FOR THE YEAR 2016 (UT) =============================================================================== January 2016 -

  11. Hi, what's the best scope for close-up photos/video of the Moon ? I read that the highest practical power worth going for is 300x due to atmospheric conditions etc, i also read that refractors are better resolution. I'd like to photograph/video close-ups of crater edges, mountains etc .. I'm pretty sure i should get a skywatcher due to all the good reviews and their price vs performance. Thanks for any help
  12. Hi, since quite some time I wanted to image a ISS moon transit. After my successfull double ISS solar transit I tought that could be another nice "thing to have". After all the fuzz about the super moon I decided "I need no sleep!". Since my Mak127 with my Nikon5100 is barely able to frame a "normal" moon, and not able to get a full moon on video, I used a Vivitar Series 1 Zoom adapted to my ZWO ASI 120MC on my NexStar SLT. That left me with quite some low resolution but I tried anyways. The night was very clear, there was just one thing which worried me. The big walnut tree could be in the way... I tried to measure and plann with stellarium and came to the conclusion that it would work from my terrace, sitting in the warm house imaging. First I wanted to image from a window in the first floor but that would have meant very bad air or let the room cool out heavyly. I took some nice shots around midnight and again slewed the scope to the expected position, just above the walnut tree. So I sleeped a bit and started to align the scope again at 4:00 MEZ, the transit was expected at 4:25:40. The moon was high enough still and I was quite sure it would work out. At 4:20 there was suddenly some strange shadows, then a trunk started to "move in", dang not enough time to pack the telescope and move to the garden. I hoped that I could make it to a gap in the tree in 5 minutes, but no.... So I ended up with a successfull imaged transit but having some shadows. I get now the chainsaw... ;-) Spot the ISS close to the center. The incredible 58fps of the ASI produces nearky a continous line of ISS outlines: So now I am tired but the outcome was despite my error quite ok. Just preparing a video showing the realtime transit. Cheers, Carsten
  13. After what seemed like eons, I had a slight break in the clouds for an while just after the France v Albania footie match which revealed the moon. So, after a little observation I decided I'd try a hand again at getting a shot of it with my IPhone 6+ through the eyepiece. Took quite a few shots, so going to work on some of the images, but for now I thought this one came out pretty well. Taken through my ST120 frac, with my 17mm Vixen LV EP. Originally with a blue filter to take some of the glare out of the moon, but tweaked on my IPad to show some of the seas better, so it turned out black and white instead.
  14. Hardly had time to use my telescope since moving house but finally managed to get out for a very quick look up at the moon and about 20 minutes of trying to get a decent picture in between fireworks. Here's my best effort from tonight.
  15. Just thought I would post these single frame shots of the Moon with Earthshine. I took them whilst I was waiting to see if I could catch a glimps of C/2011 L4 (PANSTARRS), but no luck! Taken with a Canon 1100D on a Slick 88 camera tripod. Settings: 70mm & 210mm focal lengths, F/4, 2/5", 400 ISO. I believe the comet should have been directly below the Moon by about 5-7 degs, but there was some cloud along the horizon with haze above that, which I think is where the comet was!
  16. Hi guys, It has been a while since I last visited this forum and thought it is a great shame. A while ago, I figured how to properly attach my Prestigio webcam to a telescope using spare part from Hyperion Zoom and got around to get myself some motor drive for my 4.5" newtonian on a EQ2 mount. With somehwat limited tracking capabilities, I was finally able to get down to some wannabe serious imaging, and my first stop was the Moon last night, although the seeing was terrible. I just wanted to share my results with you, recieve some feedback and tips from you in the community. Setup and imaging details: 114/900 on EQ2, basic motor drive (focusing was a nightmare) Prestigio PWC2, most basic 2x Barlow Registax, ACDSee 6 Pro Range of resolutions/fps/exposures So, what do you think?
  17. After a great hour viewing i stuck the dmk 21 mono into the 9.25 sct and put the IR pass 742nm filter and did a few barlow shots then just some random rilles ect enjoy i did avaerage 1200 frames 900 stacked
  18. Amazingly, after a foggy day in Selsey, it cleared just in time for the eclipse. Here are a couple of shots of this rather short event... Pete
  19. Hi all, A while since I've posted. I captured enough frames to build a full disc lunar mosaic on the evening of the 20th. The build is ongoing - this is how far I've got so far. Sorry it's a bit large Also - here's a bit of a shocker with Copernicus

  25. Hello All, Returning to astro after a break. Is this moon filter any good? http://www.amazon.co.uk/New-2012-Crystalview-telescope-eyepiece/dp/B00A6PASTC/ref=sr_1_4?ie=UTF8&qid=1385415694&sr=8-4&keywords=moon+filter+for+telescope I had a cheaper one which was awful, I don't want to be blinded; if not this could someone recommend an alternative?
