  1. November 14, 2016, the closest moon approach since 1948! A scant 221,524 miles away, the moon won't be nearly this close again until November 25, 2034. Smoke from North Georgia wildfires casts a thin veil over the night sky, but not enough to blot out the SUPERMOON! Cheers and high tides! Reggie
  2. Hello Astronomers, After a 5 month break from imaging due to moving house, I managed to setup the gear and get a couple of images that (I think) are worth sharing. These are quick processes of the data captured, but I'm happy enough with them to share. I'll spend some more time processing the data later and if it's an improvement I'll reshare the pics. Thank for looking, Mariusz
  3. It occured to me that I should share with you the timelapes of this year's Mercury transit as seen from Czech Republic. The clouds have parted for some 20 minuts, allowing me to capture this timelapse. I shot it with a modified webcam, Baader 2.25x Barlow and UV/IR cut filter, using my former SW MAK 102/1300.
  4. Hi, all! I spent some quality time with Mars this past weekend as Syrtis Major was well-placed for imaging. I connected a Shorty Barlow (2X) to my little Orion Electronic Imaging Eyepiece (analogue version) on my Orion StarMax 127 and got a cool video of the red planet. Some atmospheric turbulence got in the way because of the relatively low elevation, but features were clearly detectable as was the stunning red hue. I was so excited, I even composed some space music especially for the event! It's a good thing I chose to image at that time because clouds have rolled in this week (of course) and threaten to block Mars' photons on the night of actual opposition. If possible, though, I will be out there on May 22 (and on May 30 for the perigee) to shoot some more video! I hope you enjoy my video contribution and the music! Cheers! Reggie
  5. Anyone planning to image comet 252p/linear this week? Comet 252p/linear will pass close to Earth beginning this weekend (closest distance on Monday). It is passing close to the Large Magellanic Cloud and I understand that it will only be visible from the Southern hemisphere until the end of the month when it will begin to be visible from the north as well. Is anyone planning on trying to capture images as it gets close? For me, here in the Blue Mountains above Sydney, the forecast is not good; cloudy every night except Friday 18th ( 3 days before closest approach ). I’m going to try to see if I can capture anything useable on Friday. Does anyone have any advice about settings to use? From my estimates/calculations, during Friday night, the comet will be travelling with an apparent angular velocity of about 0.3” / sec. With my setup that’s equivalent to about 1 pixel every 2.5 seconds. So if I track on a star I will need to use a ‘very short’ exposure if I’m going to freeze the comet’s motion ( I’m thinking of trying ISO 3200 @ 2s and increasing this until the blur is too noticeable ). I suppose I could try and track on the comet itself but I’m not sure that it will be bright enough; I have come across various predictions in the mag 5 to mag 7 range and again I would need a fairly short integration time in PHD if I want to freeze the motion of the ‘guide star’. Of course, this won’t help with the background stars so I would still need a short exposure if I’m going to freeze both the comet and the stars. Any ideas, thoughts? Sorry for the rambling post, it reflects a fairly fuzzy post lunch mind
  6. Messier 51 - The Whirlpool Galaxy by Chris Kennedy, on Flickr Happy to get this one in, as it's now snowing here in Mansfield, England! Friday night/Saturday morning was the first clear night I've seen in over a month, and thankfully the 11mph wind was coming in from the North, so the gear was sheltered. My garden is less garden and more swamp currently, indeed expecting Yoda to come out of a hole and point out the first temple of the Jedi. So I pre-sank the tripod a few inches in to the ground and then leveled it - was a pain to pull it from the frosty hard ground the next morning! I originally got my ATIK414ex for narrow band imaging, as light pollution in suburban Mansfield is awful and rather limiting, but I can't resist some of the more iconic galaxies! Even if processing can be tricky! As there's a Moon rising - will probably spend my next session going over M51 in H-alpha, really to bring out the star forming regions, perhaps also a few really long exposures to add background stars. Imaging Details: RGB Sets: R x 30 | G x 30 | B x 30 - 6 hours initially, but re-shot 15 of the R set as M51 was higher in the sky, so sky background levels where better. Optics: Meade LX90 8" SCT, f6.3 Focal Reducer, Baader RGB filters. Camera: ATIK 414ex, -17c, bin 2x2, 240s Guiding: ASI120mm, ATIK OAG, error 0.7 - 0.9", PHD (Also used for drift align) Datasets: R 30x, G 30x, B 30x, Per channel flats Processing: DSS, Photoshop Conditions: Ground saturated, pre-sunk tripod, 1c/-1c, Wind 11mph (sheltered), occasional cloud cover (10%), Suburban light pollution.

  8. Comet 252P/LINEAR passing through the constellation Mensa and approaching Earth on the 18th March 2016 by Mike O'Day ( 500px.com/MikeODay ). Comet 252P/LINEAR is a near-Earth comet that was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) project in April of 2000. 252P has an orbital period of 5.3 years and passes close to the orbit of the Earth. In 2016 it passed 'very close' to Earth (in astronomical terms) on the 21st of March 2016, when, at its nearest, it was only 14 times the distance to the moon (~5.3 million kms). This image was taken three days before comet 252P/LINEAR made its closest approach when it was at a distance of about 5.9 million kms ( position as at ~16:22 Fri 18 Mar 2016 UTC as seen from the Blue Mountains above Sydney Australia ) Links: https://500px.com/MikeODay http://photo.net/photos/MikeODay Details: RA 06h 40m 38s, Dec -80 deg 18' 37" (Epoch 2016.2) Skywatcher Quattro 10" f4 Newtonian Skywatcher AZ Eq6 GT Mount Guiding: Orion Shortube 80 guidescope, Starshoot Autoguider, PHD2, (guiding on star) Baader MPCC Mark 3 Coma Corrector Hutech IDAS D1 light pollution filter Nikon D5300 (unmodified) Field of view (min) ~ 74 x 49 Stack of 185 x 7sec images @ ISO6400 Pixinsight (incl. Comet Alignment tool) Comet moved ~ 475 pixels East and 1470 pixels South during the time the images where captured. In the image Up is North and Left is East.
  9. When we observed the Perseids meteor shower 12 August 2016 my girlfriend Gunilla managed to shoot a great smoker. She uses a Canon EOS M with a 22mm f2.0 lens wide open mounted on a tripod. You can see the GIF animation here: http://astrofriend.eu/astronomy/my-astronomy-photo/meteor-shower/perseids-2016.html There is also a full HD animation link at the end of the text. Really nice and I didn't know the smoke can last for almost ten minutes. Lars and Gunilla from Sweden
  10. Hi All, After imaging Venus last evening, when it became visible it was already low in the west less than 30 minutes from it setting behind the mountains. Being so low in the west and the amount of turbulence/heat shimmer I was fighting when imaging, I think that I might not image Venus this season again, so I'm sharing my collection of Venus phases I captured between 1st December 2016 and 20th February 2017. Thanks for looking, Mariusz
  11. Although not organised by SGL, it's usual for us to have a thread for SGLers attending - so you can easily find each other and say 'hi'! So, I'll be on Red 354 Mon-Thur and then I think Blue 267 Fri and Sat (yes, that *will* be a pain!!)
  12. The skies cleared and I jumped at the opportunity to image Mars at actual opposition and here is the result. This time, I used my barlow and imaging device with the Orion SkyView 180, yielding a larger image. There is a little atmospheric turbulence here and there but some moments of really good seeing and suitable frames for stacking. I used the same music for this video as I did in the "Mars Near Opposition" video. Enjoy! Regards, Reggie
