  1. 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.
  2. 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.
  3. 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).
  4. I imaged the conjunction around 17.30hrs GMT with my Startravel and ASI120MC camera on the SLT mount (+fixed wood tripod). The image scale with my C8 would clearly have been too large. The image, processed in Registax6 from 200 frames, is shown below. The image is shown horizontally flipped to match the telescopic view with star diagonal. I puzzled for some time over what exactly I had captured, but the centre dot is Mars (overexposed) the faint dot at lower L is Neptune, and the brighter dot at upper R is the star 81 Aqr. I also took a run which has Mars only slightly overexposed, and looking very small, and inevitably not capturing Neptune.
  5. I have continued to image Mars as it moves away. It is getting smaller, but on the other hand I don't have to get up in the middle of the night, the dust storm has subsided, and it is gaining significantly in altitude. Here is a series of images taken in September and early October, all taken with a C8 SE, ASI120MC, +ADC, processed in Registax 6. The seeing was often poor, but seemed better on Oct 3.
  6. Hello all,as a totak noobie and not just green behind thr ears but all over ?. Ive had my first scope for 7 days now a 2nd hand skywatcher 200p dob, i only have the 2 eye pieces that came with it. I decided to go out in the communal garden again tonight asbthe sky looked good,i got out at 8.30 to give the scope time to cool down and get muself comfy. It was a lovely fairly clear night.And for the first time i managed to get Saturn in my finder scope after finally sorting out its alignment on friday, i started off with tue 25mm eyepiece saturn was tiny but i could cleary make out the rings i was gob smacked so happy and excited i quickly fumbled for the 10mm eye piece and slipped that in a slight adjustment of the scope and saturn was slightly larger and the rings alot more visible wow wow wow i am still on cloud nine it was amazing,i looked at it and followed it for what felt like half an hour.my wife bought me a cup of tea and she had a look to and a couple of my neighbours were very impressed. I then waited for mars to move round and quickly focused on it and i started with the 25mm and then moved on to the 10mm. Before tonight i wasnt very impressed with the 10mm but it did a good job tonight. Im still buzzing and im off to bed now. Just thought i would share with all you wonderful people. Many thanks and best wishes From me Dave ?
  7. For once I set up my two catadroptic imaging scopes together to see how they compared, and how well the smaller one cut through the crud. C8 SCT on SE mount, ASI 120MC, ADC, processed in Registax6, 3000 frame video. Celestron 127mm Mak on Nexstar SLT mount, wood tripod, ASI120MC , ADC, processed in Registax6, 3000 frame video. The 127mm images are slightly smaller, placed second. The bigger scope seems to do better. I thought that Saturn did not change much and was just a seeing test target, but the shadow of the planet on the rings is now distinctly asymmetrical. The dark smudges in the C8 Mars images correlate well with real features. Mars altitude about 11 deg. The dust storm seems to be over. The seeing was better than it's been for a while.
  8. Okay I need to admit I am very amateur when it comes to knowledge of the celestial bodies. I do however believe myself to be intelligent (ish) but more importantly a deep thinker. My question is. Has any studies been done on the temperature difference on the Mars surface when storms envelop the planet for weeks? I can only imagine that it gets hotter! Maybe not beach time hot but possibly enough to thaw water trapped as ice near the surface. Look at Venus for instance, it covered in clouds and is hotter than Mercury!?!?!. So surely weeks of sand storms on Mars would raise the temperature there. Liquid water..... potential life? Like I say I'm just a deep thinker who thinks he's intellengent, no basis behind it other than theory.
  9. Hi Astronomers, Just sharing with you the picture of Mars I imaged on 1 August 2018. Clear skies, MG

  12. Last night I randomly woke at 3:15 and when ever I get up in the night i can't help but have a quick peek at the stars as the street lights are still off. I noticed Mars in the south but more bright than I've ever seen it, it really stood out. I'm wondering if this extra bright appearance might have anything to do with the colossal dust storm playing out at the moment and the particulate reflecting more light in the atmosphere? Any thoughts. Campbell
  13. Night of 12-13 June. I had not had a go at Saturn and Mars for some time, so set up the C8 to image them. Kit: Celestron C8 SE SLT, ASI120MC, ADC. Seeing: initially poor but improving through night. The Jupiter images were unexceptional, but the Saturn ones resolve the Cassini division well (compared with my earlier efforts). The rings look odd - I wonder if this is the conjunction brightening I have read about? Mars was very low when imaged at around 2am BST. I packed up because I was tired and cloud cover was forecast. I still got some surface detail.
  14. Did anyone see Jupiter and Mars close together late last night / early this morning ? The Jovian moons were especially impressive as they were bunched up together like cat's eyes on both sides - reminded me a bit of Sigma Orionis
  15. Hello All, Another of contribution to the planetary imaging contest... this is Mars taken on 10th June 2018. I plan to image Mars every so often to keep an eye on the development of the dust storm, and hoping that it will not destroy our view of Mars last week in July and first week in August. Taken with a my 8SE - 8" SCT with the Skyris 618C at F33. Clear skies.
  16. Hey SGL, So i have just got out my telescope for the first time and was able to locate Mars so thought i would take a look. So i have set up my Skywatcher 150p and am unable to see anything worthwhile... All i see is a slightly red looking sphere with absolutely no detail whatsoever... I googled to see what Mars should look like through a telescope and it is nothing like what i can see! Here are the eyepieces i have been using: (all came with the telescope) 10mm 25mm Wide Angle 2x Barlow So i am able to achieve on my 750mm scope a max of 150x magnification i think (2x Barlow with the 10mm eyepiece), is this not enough to see a clear picture or is there something else wrong with my telescope? According to the seller of the telescope it was ready to go with no need to calibrate so i am a little confused... Any help would be great! Thanks
  17. It was clear in South Oxfordshire from about eight o'clock last night, though it took a while for the last of the cloud to clear, and I set the scope up to have another view of Jupiter and Mars. The seeing was poor for quite a while and I only caught fleeting glimpses of the GRS on Jupitet at 300x. I watched it from mid transit until it dissapeared but it was quite tricky viewing. There were tantalising periods where the view improved, and fine detail emerged, but these were very fleeting indeed. As Jupiter dissapeared behind the neighbours' house, Mars started to emerge from behind the trees and so I set up on this without too much expectation. Initially there were no obvious details but after a while some detail started to appear. Syrtis Major had already transited out of view but there were glimpses of dark bands near to the poles. There was a large white patch at the South pole and a very much smaller white patch at the North pole. The small patch corresponds to the melting ice cap while it turns out (from the latest FB post from Damian Peach) that the larger patch is actually a cloud over Hellas basin. I also noticed a white patch on the edge of the disc away from the poles and I reckon that this might have been the cloud over the Elysium Mons volcano that Damian Peach also managed to photograph. The seeing improved as the evening wore on but then Mars dissapeared behind another tree. I was quite pleased with my night's observing after a tricky start.
  18. IR (G) B Mars from the morning of the 7th of March. Was really testing out different optical configurations for this one. If I can find time (ha ha) I'll build the RGB. Pete Lawrence
  19. Two shots of Jupiter and Mars from last night. The seeing was not the best but better than recent nights so I thought it was worth posting. In use: CPC800 & QHY5l-II. AVIs post-processed using PIPP, AS!2, Nikon CNX2. I'm still getting to grips with processing Mars...
  20. My time spent on Saturday 29th round about 11-12pm BST resulted in these images: Both are taken using the NA140SSF with televue 5* powermate (~f/27)and astronomik filters. Mars is Red and Saturn is L. Mars blue channel wasn't worth keeping, the frame rate on the ZWC120 was too low and the image so poor. G was better, L better still and R best. What is the best opportunity for synthetic here - re-use L as blue ? Both acquired in FireCapture for 9o seconds using image stabilisation and stacked in registax. I tried an alternate path of Pipp + AS2 but AS2 put some horrible artifacts around the limb that Registax didn't. I was surprised at how much detail came through on Mars and how poor Saturn turned out to be but it was really low. regs Mike
  21. Nice and steady seeing conditions last night. Mars at almost 17 degrees! First one is without the ADC, the second with. Not sure whether I have over-processed them.
  22. Hi guys, Any tips for observing Mars? I've observed Jupiter and Saturn many times and am able to extract a good amount of detail using my ED 127 Apo and my C9.25. However Mars seems to yield no detail at all. It is less than 20 degrees up in the sky and I'm not using any filters. Are filters the solution? If so, which colour? Cheers Fish
  23. Hi, all! I spent some quality time with Mars last 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
  24. Hiya ... despite being knackered yesterday (after a long day out in Weymouth hanging around while my eldest son did two shows in the chorus of the musical Joseph), I really needed a night out under the stars ... Got home at about 11.15, and was set up with the dob at around 11.30 (still twilight!). I started off with Mars and Saturn. Had a good look at Mars, but couldn't detect any detail. Saturn was fantastically crisp at x136 in the ES/82 8.8mm: clear Cassini division, surface banding ... The Milky Way soon appeared as a soft cloud overhead, lacking the fizzy sparkliness of other nights, but nice nonetheless. The Veil neb in my ES/62 24mm plus OIII filter was okay, not great. In fact, although seemingly clear, fainter objects and nebulosity was underwhelming (M31, 51, 81, 82, M16), and lacking in detail. Star clusters, though, were amazing. M11, M3 & lots of other 'couldn't be bothered to identify' clusters in the Milky Way were all fantastic! M3 (I know, not in the MW!) in the ES 8.8 in particular, was lovely; really dense, like fine salt grains ... The night was looking like it might be spoiled by a local 'party' that seemed to go wrong, with arguments and shouting emanating from a local farm, storming's off, more shouting, a girl crying, a shotgun blast (!), more crying, then drunken laughter, recriminations, then more storming's off, a pickup truck screeching off, then back ... honestly! Anyway, I was thinking of packing up around 1.00 anyway, as the waning moon was due to clear the hills, whereupon the 'party' seemed to calm down for a bit, so I thought I'd take a look at the moon before heading for bed. By this point I'd kind of resorted to scanning around with my 10x50s, and pointed them at the moon as it rose ... Then ... hang on, what's that? That doesn't look like a background star ... out with Stellarium on the phone and, 'Wow!' That's Neptune (in the same FOV as the moon!). What an amazing sight. I quickly switched to the scope, and tried a variety of EPs. The planet remained a shimmery orb, but a truly magical one at that. I hung around for another 20 minutes or so, entranced by the combination of our planet's satellite and the distant ice giant, before finally packing up. Amazing. As it turned out, I might as well have stayed out. Didn't get to sleep for ages, as I was buzzing from such a fantastic experience. Cheers, Kev
  25. We finally had a clear night here so I had a go at Saturn and Mars even though they are fading now. I used the C9.25 with a flip mirror and 2.5 Powermate with the ASI224MC. If only I could have done this earlier I'm sure that the results would have been better. Anyway, thanks for looking. Peter
