  2. Got images of Jupiter and Saturn in the morning and a tiny Mars in the evening. Saturn was very low and a fence may have blocked some light. Apparent diameter of Mars is now below 5" and the evening seeing was poor. Used: CPC800, ASI120MC, ADC, processed in Registax6.
  3. Hello friends I captured to night to phone oneplus 2, 4s long Sutter photo very light is Mars and upper side Saturn.... I want more clear image but how?!!!!
  4. This morning I had another go at imaging the planets with my recently acquired ASI120MC camera, and the 127mm Celestron Mak Nexstar SLT. While the images are not that great compared with other peoples' work, I count them as a useful result as they show as much as I could see visually with the same telescope in the same session. In particular, the Jupiter pics clearly show the Great Red Spot, which I could not see visually this morning and have rarely seen with this telescope. The seeing was not great and I have seen more on Jupiter visually on other occasions. One Jupiter image is the correct way round, the other still flipped horizontally. I focused on the moons.
  5. Hi Stargazers, After a lot of work and help from the great Damian Peach I managed to get some really good images of Jupiter Mars and Saturn despite a total spend of just £100... and I made another bonkers Astrobiscuit video about it which I hope you enjoy. Mr Peach really helped me pick my nights to image and the other big surprise was how good the canon 600D is at planetary. All comments/ advice/ criticisms most welcome...

  8. Hi, The link below is for the night sky next week, in the Southern Hemisphere. Because the Moon will be up, it focuses on the Moon, Jupiter, Mars and a few clusters. The night sky for 22-28 January 2018
  9. Before I focused on meteors (got clouded out ), I took advantage of a break in the clouds in the southern sky and took this wide-angle shot of the beautiful triangle formed by Saturn (top), Antares (bottom left) and Mars (bottom right) in Scorpius. The waxing gibbous moon is hiding behind a tree branch. Going to try for some Perseids all this weekend while dodging clouds!
  10. Hi All, I was lucky to have had a night of particularly clear and crisp seeing. I was planning on doing nothing more than observing tonight but after seeing nice steady and detailed views of Mars and Saturn at a magnification of 406X in my 8SE I was told by missus that I will regret it if I don't image these planets tonight.. I'm glad that I did. I'm stoked with the results so I'm sharing them with you. It does go to show that seeing and collimation are extremely important when imaging. Thanks for looking. Mariusz
  11. Hi all, I thought I'd share my observation from this night. At approximately 22:00 local time I was already setup and ready to image Mars and Saturn. As I'm using a mirror diagonal for framing/searching purposes I looked through it and focused using my 40mm LV eyepiece. What I saw in the eyepiece took my breath away. The disc was massive and detailed. I stack Baader Contrast Booster and Neodymium filters for planetary viewing since it does make a considerable difference in revealing detail and increasing contrast. Mars showed a big disc with two CLEARLY visible patches on both the "north" and "south" (equivalent to earth location polar cap regions). There was a clearly visible dark greenish borders around the white patches. The bottom part was white and crisp with a irregular dark greenish patching bordering it from the pinky orange center of the planet. The equator region showed some dark markings around where, I think, Olympus Mons is located. Now I'm not saying that I spotted Olympus Mons in my 8" SCT but I'm thinking, and hoping, maybe... there was definitely something there along with other more subtle spots and shades. This was hands down the best view of Mars I've ever seen. After Mars I had a look at Saturn, it was big and clear although it was not the clearest I've ever seen. Last year I had a clear view of Saturn's cloud bands and a crisp Cassini division surrounded by 5 of its moons (that was the best view of Saturn I ever experienced). This time the Cassini division was there but not as defined as before and any cloud bands were a struggle to see, and the Cassini division was coming and going. There were 4 moons around it glistening in the dark. I know some of you might be wondering why I have seen such big discs using only a 40mm eyepiece. The magnification was at least 250X-300X judging by the size of Saturn in my past experience near opposition using nothing but eyepieces and a diagonal. The reason why the magnification was so high with the 40mm was because it was a bit of a distance away from the visual back and I was also using a Celestron 2X barlow, due to me being setup to do planetary imaging. The lineup was a 2X barlow, 1.25"-2" adapter, a Vixen flip mirror, on the mirror the 40mm eyepiece, and behind the flip mirror were a filter wheel and a IS 618 CCD as shown in the pic. Does anyone know how to work out the actual focal length in a setup situation like this? The pictures didn't come out as crisp as I though they would after the seeing I was experiencing, I'm thinking that the line up caused a bit too much magnification. When I tried the 2.5X power mate the magnification was less, about 60% of the size with the Celestron 2X barlow, I think the TV 2.5X powermate should be labelled 1.5X. I didn't capture any images through the PM due to Mars moving out of the optimal imaging position, coming down with Bronchitis and starting to freeze through my layers of jumpers so I ended my session. The views I had I will definitely remember for a long time and I'm looking forward to the next Mars opposition since it'll be another 38% closer and again will move through the zenith visible from my location... now thinking about a 16" dob for those views!!! Thanks for reading, Mariusz
  12. Mars from last night with the Skywatcher Pro 150, EQ5 manual tracking with Xbox 360 camera, 2x Barlow, UV/IR cutoff filter. 3 different processes from the same stacked image. 30fps, 3500 frames stacked in AS!2 from 5200 total, wavelets in RS6 and finished in PDN.
  13. Ok, so i had my first run at planetary imaging yesterday evening, which was disappointing to say the least :/ I was trying mars. The setup went smooth, and imaging went ok as well, but the seeing was very bad and especially the heat of the atmosphere was high, which blurred the images to the point that mars' image was not even a sphere (see left image). There are , however, also other probable issues: + Short focal length (800mm) with an 8mm EP, resulting in only medium magnification + problems with focusing the blurred image + missing real astro darkness (24th of june) + days' high was around 28 deg c, although it had cooled down to 22c at imaging time... Have you guys & girls tips on how to improve? The resulting image from stacking 1600 out of 3800 images was a mess, but at least spherical
  14. Just a quick process of one of the 26, 3 minute videos I took between 22:00 & 00:00 UT on 8th April. It should have been more only I set Sharpcap running and went into the conservatory to wait and watch through the window. Next thing I know it's 02:30 UT and the laptop has turned itself off and the mount is no longer tracking Mars!!!! Anyway, this is the first 3 minute video: processed in PIPP, stacked in AS2! and wavelets done in RS6. Equipment: Celestron C8 XLT, Revelation 2.5x barlow, Philips SPC900NC with Baader neodymium IR cut filter, CGEM mount. Not a patch on other images I have seen on the forum but my best Mars to date and I have a lot more videos to process yet. I was hoping to get enough to do a short rotation video, but I'm not sure 2 hours will be enough. Teach me to fall asleep! :coffee: Just as a last thought; would it be better to leave the IR cut filter off in future?
  15. I’ve been enviously watching the detailed Mars images appear here on SGL from the 8+ inch scopes, when my previous efforts over the last couple of weeks have been absolutely awful. You wouldn’t have known it was a planet, it just looked like a small fuzzy splodge, through the SPC900 or the DMK21! I’d been starting to wonder whether that was all I would be able to get on Mars, and I’ve been struggling to reconcile that with the view I had of Mars a couple of years back through the little Mak, where I could see bags of detail (by Mars standards anyway! ). Anyway, just after midnight I set the camera up to run on Jupiter and the moon for a while, before I realised I was about to lose Mars behind a huge tree for an hour or more, so I swung round and had a crack at it. Thought I could see a hint of detail, just a dark patch on the right hand side when I was trying to find the right settings, so figured I must be close. Did 3 runs with different settings, praying the dew didn't get any worse, packed up for the night and came inside. OK, so in hindsight, imaging the ‘Red’ planet in mono means that a certain amount of the wow factor here might have been lost, but I was dancing around like an absolute loon when this popped up in Registax… Far from perfect I know, but a huge ‘personal best’ for me on Mars. The seeing wasn’t great here either, though it wasn't terrible like it has been recently, though most of the frames looked real fuzzy. This gives me some hope that I might even be able to improve a bit more over the coming weeks. This was 5 minutes at 30fps, Exposure -6, Brightness 15, Gamma 97, Gain 809, with a stock Skywatcher 2x barlow, run through PIPP and then stacking the best 20% in Registax. I’ve been on a high ever since! Picked up a couple of reasonable lunar shots as well – I think the DMK21 (which I actually picked up in FLO’s clearance last year, but have had very little time / clear nights to use it) will be amazing on the moon once I get my settings and focus right. Can’t wait for Saturn to rise a little earlier – I tested the camera out very late in the Saturn season when it first arrived last year, and it outperformed the SPC900 by a mile, so even though Saturn isn’t going to be particularly well placed for us this year, I’ll be ready for it!

    Mars

    From the album: Starry Bob's Starry Shots

    The best I could get of Mars due to poor seeing and it being a pain to image.

    © StarryBob

  20. From the album: Solar System Objects

    This image is a compilation of my captures of Mars at various dates during this years opposition season of Mars. All of the images were taken using a 8" SCT at 6764mm focal length/f33.3 with an Imaging Source 21au618 and Skyris 618C CCDs. Since all of the images were taken at the same focal length and the same telescope, this is a good representation and comparison of the size of the martian disc as it got closer, was at opposition and was getting further from Earth.

    Sketch of mars

    From the album: Astro sketches

    Sketch of mars through my 7" refractor. Very low to the horizon so a fair bit of atmospheric dispersion and a lot of "shimmer" but the polar cap and some features were still visible even this far past opposition (November 29, 2016)
  22. Another tricky low one, but certainly viewable. At 5am Mars will be 10 degrees above the horizon, with Saturn only 1 degree 17" away. Best seen with binoculars or naked eye, telescopic views will likely be poor due to the low altitude.
  23. I had another go at imaging the shrinking Mars, this time without and with a x2 Barlow lens. The results are better with the Barlow, which is what one is led to expect. For whatever reason (probably bad seeing and/or low planets) when I tried a Barlow previously it just made the blur bigger. Equipment: C8 SE, ASI120MC, x2 Skywatcher kit Barlow element screwed directly into 1.25" barrel of the ZWO camera. This does seem to give x2 in practice. I did not use an ADC on the grounds that I shouldn't need one with Mars at an altitude of over 40 degrees. 3000 image video captured with Sharpcap. Processed in Registax6. I found that the Sharpcap exposure histogram did not appear to work on such a small image, so had to estimate the exposure. Yes, optical ADC correction would be better, but the dispersion seemed very small. Blowing up the image x2 in Registax showed a small colour fringe, which I took out with a single point of correction. The images show some surface detail though the contrast is low (if you are using a flatscreen try viewing from below: ?) Mare Sirenum, with Mare Acidalium just discernible foreshortened at upper right.
  24. Here is an image of Mars I made on 9 Jan this year, with a C8 SE, and ASI120MC camera. The images are rather small (around 7" dia). Mars is now much higher in the sky than at opposition, so it seemed worth taking a few farewell images as it diminishes in size. Captured with Sharpcap. I did not use the ADC - the images are corrected for AD in the processing in Registax. This is from a run of 3000 images. I have included a x3 Photoshop zoom of the same image to indicate the size of Mars at opposition on the same scale. I was quite pleased to record some surface detail, corresponding with the position of Syrtis Major. If I'd had more time, I could have tried some images using a Barlow lens. I have just discovered that I can unscrew the lens section from a Skywatcher x2 Barlow and screw it onto the 1.25" nosepiece of the ASI120MC, which will give a more modest zoom (I think).
