  1. Hey guys. Thought about starting this thread. I feel like we all should inform eachother and newer members alike about the magngifications that can be achieved on planets,that provide the best sharpness/size ratio,depending on the scope and seeing. After this thread has grown a bit, i feel like this should be pinned,as to provide a little guide to newer members that are not experienced with planetary observing,as many will be fooled with the typical 50x per inch of aperture and get disappointed when they find that that image will be dim and blurry. For my 8” F/6 Sky-Watcher Dob For Saturn i like to use 150x in medium seeing and if i want something a bit bigger , switch to 240x ,which will give me a bigger,but blurrier image.iBut In good seeing, i found that 240x was very usable.When we have perfect conditions, i m certainly trying 300x. Mars, isnt very big in the sky right now,so even at high magnifications like 300x it still appears as a small orange dot. For observing mars,I suggest waiting for it to reach opposition.It benifits hugely from it! However,this happens once every 2 years....But 5ere are other planets to keep you occupied until then, such as jupiter,saturn and Venus. For Venus, i use 50-100-120 depending on its phase. For Jupiter, i like to use 150x, as it provides a very sharp image,with key features of the planet such as bands being very detailed.Waiting on my 6mm UWA Skywatcher to bring it to 200 and see how that plays out. Be careful! Don’t magnify jupiter too much, as it will loose much of its features and sharpness. Neptune and Uranus: These two will not impress, but are certainly have a nice colour to them. Even ar high magnifications, such as 300x and 400x, they will look like small discs with color in them.Uranus will look be colored green and Neptune a fainter blue. Mercury About mercury...Havent gotten the chance to observe it ,so the guys will have to inform you about that? Feel free to give your own opinions as to give members a wider source of information to help them observe better ! Cheers and clear skies. Kronos
  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. Last night was the "Virtual Star Party", a live show that lets amateur and professional astronomers show the night sky from their telescopes. If you've never seen it, or missed out on last night's episode, catch it here: Last night I brought Jupiter and Mars to the VSP, and despite it being 3:30am when the show finished for me, I hung on for an extra hour to get my first image of Saturn for 2014! All the planets (and Europa) where shot using the exact same set up, so the image is a good example of their relative sizes currently. Equipment: Meade LX90 8" SCT Meade 2x Shorty Barlow ASI120mc! My scope needs collimation as it was recently repaired and seeing conditions where less than favorable, but no matter how many times I look through my scope, these planets blow me away!
  4. Hi folks, I captured a few shots of Mars and Saturn in the early hours of Monday morning. Unfortunately the Saturn images were waaaay too dark and dim to be useable. Even though they looked bright enough on my laptop screen when I play the avis back now, I realise I needed to bump up the settings significantly before I’d be able to create an image recognisable as Saturn! So anyway, boosted by my attempt earlier in the month with the 2x barlow, I thought I’d have a crack with the 3x. Truthfully I was pushing my luck as the seeing was pretty poor, and very few frames actually captured the round disk of Mars. I believe this explains the ‘mist’ of noise around the planet in the images from both cameras! When I ran the DMK21 version through Registax, I noticed a white splodge on the upper right section of the planet itself. Bit frustrating I thought, but then there’s streetlamps everywhere here and I’m using a £9.99 3x barlow of no known brand, so these things happen. But when I processed the SPC900 version taken about 10 minutes later, it cropped up again, and appeared to have moved a distance relative to the other features on the images, in line with Mars’ rotation. Any ideas? In comparing the cameras, I think these confirm the suspicions I’d formed from the Jupiter images I'd managed earlier in the year, that this camera is very strong in good seeing conditions, and picks up a lot more detail in good seeing than the SPC900 does. However, in poor – average seeing, the SPC900 actually does just as good a job really. I guess ultimately any equipment we have is going to be limited by the atmosphere we have to look through... Can't wait to have another crack at these two fascinating targets, hopefully in better seeing, and when I get my settings right!

    Opposition of Mars

    Mars at Opposition, best placed for viewing ie at its largest apparent diameter of 24.3 arc seconds, visual magnitude -2.8 and a distance of 57.8 million km. It transits at 1.15am but at a height of only 13.2 degrees above the horizon from London. Best bet is to get on a plane and head South!

    Moon and Mars Conjunction

    A tricky one to see being very low in the sky just before dawn. At 5am the Moon is at around 15 degrees altitude, with Mars just under 3.5 degrees away Best seen with the naked eye or binoculars

  8. Mars will appear at a perihelic opposition from the Sun during the night of 2018 JUL 26-27. Greatest brilliance at magnitude -2.8 is expected on JUL 28, with closest approach to Earth on JUL 31. It will be nearly as bright and close as in 2003, which was its closest in more than 60,000 years. Photos and descriptions of Mars during its current apparition would be welcome additions to this thread.
  9. Hello again astronomers, Looking forward to the opposition of Mars in a bit over a month from now, the one thing that has me a bit concerned is the developing dust storm on Mars, so naturally I'm keeping an eye on it and hoping, hoping hard for it to settle down... I seen a photo today showing that the whole Mars globe is dusted out, but photos like this have turned up previously, such as on the same day I took the below picture and showed a hazed out dust ball, but obviously that was not the case, although there is definitely a dust storm developing as shown in the actual pic and "Mars Globe" simulation image. Let's hope the Mars Clears up by August... this year.
  10. Hello, i have a presentation for astronomy and I need to understand how Kepler received to find the elliptical orbit of mars. Therefore I use his book Astronomia Nova and due to its hard to comprehend its scientific language, additionally I use this website too: New Astronomy Well, I have difficulties with understand two main aspects: First; In Chapter 51 of Astronomia Nova, Kepler determines the distance between Mars and sun. From that he corrects his hypothesis of chapter 40. (Chapter 56) Picture After that in Chapter 58 is rejects his hypothesis he made in chapter 56. What was the problem? Actually the distances were correct but were the angles wrong? Is that the case? If yes, how can the distances be correct but not the angles? Can anyone tell me the idea behind chapter 56 to 58? Second; In Chapter 40, kepler suggests a model for the orbit of mars. there are also distances from sun to mars. But in Chapter 51 he calculates distances from Mars to Sun again and then he prefers another orbit. Whats the difference between Chapter 40 and 51 with the distances? Due to english is not my first language, maybe i miss some important detail. Thanks
  11. 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
  12. After a few nice views of the sun today in the 4", I switched out the Herschel Wedge for the Zeiss prism, Barlow and Leica zoom to have a go at Mars and Saturn. I wasn't expecting much after such a hot day, but the reality was far better, some of my best views of these two this year. As ever, I'm a little uncertain of the mag because of the exact spacing with the Barlow, but I was probably maxing out at x180 or so, but possibly x200. Detail was visible even at much lower levels. Emphasising the beauty of this setup, I only had about 15 mins to observe, so I carried it down to the bottom of the garden where I get a clear view of the two planets, had some nice views, then just packed up quickly, all done in about 25 mins I should think. Anyway, on to the views. Mars immediately looked great, the seeing was good, and surprisingly steady. The phase was clear, Syrtis Major obvious, and defined well. I could see the north polar cap, getting obscured by the phase now. To the south, Hellas Planitia showed as a bright area, looking a little like a big polar cap but more orange than white. These views were unfiltered, the sky background was bright and Mars itself a pale orange colour. I popped the Mars B filter in and immediately the sky background was virtually black, giving Mars a nicer apparent contrast. Mars itself appeared a deeper orange colour, more Mars like if you will . Syrtis Major appeared darker and slightly better defined, but Hellas Planitia was dimmed and I lost the polar cap. The Mars B didn't show any more detail (based on this brief view), but I did enjoy the views as an alternative. I need to try the less aggressive Mars A filter which may be a better compromise. Should also give the Neodymium a go too which is very effective on Mars, but not Saturn for some reason. Note to self, probably should get a filter slide for my 1.25" filters to make comparisons easier, I have plenty of infocus range so it should work fine. One obvious statement is the importance of focus in picking out the detail. Very small tweaks on the fine focuser significantly improved the views so it's well worth getting it right, and using a dual speed focuser if you can. On to Saturn, and again the best and steadiest views I've had this year. The Cassini division was very clear other than the thin section infront of the planet where I lost it. It was visible most of the time, but became vague when the seeing dropped off every now and then. This was only a quick session so my recall of features is a bit hazy! A and B rings were clear. I believe I saw the Crepe ring in front of the planet, but need to verify again whether this was the case. The darker section in the B ring was visible, as was shading/banding on the surface. The only moon I could detect was Titan as it was still too bright for the others; I know that at least 5 are visible in this scope under good conditions. So, a long report on a short session. I'm mainly writing it because I don't seem to have had much luck with these two so far this year, either too low, poor seeing, cloud or too busy so these views were very welcome. It's often said (by me too!) that you need to spend a long time observing to pull out the detail in planets, well last night that was not the case, detail was clear right from the start. I could have spent an hour on them, but Mrs Stu was ready to turn in, and I know better than to disobey the CEO . The images attached are approximations of what I saw, or at least they are on my iPhone. The main difference with Mars is that I could see the polar cap (in the unfiltered view) which has been lost in this image which is more similar to the filtered view. Saturn is shown against a brighter background as it was unfiltered. They may be too large a scale on a full screen, so don't look too closely . Just trying to give a rough idea without having done a sketch.
  13. 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
  14. I don't think my attempt at Jupiter from last night was well accepted so I re-edited it. I lost some detail working on it so much. Last night I imaged the 3 planets. Mars and Saturn were captured from about 3am almost directly overhead. I had to revert back to the standard 1.25" gear as the 2" gear wouldn't allow me the altitude because of the top of the mount on the Celestron Nexstar 8i. Software used Autostakkert!2, Registax 6, Rawtherapee and PaintDotNet. Captured using Sharpcap and the white Xbox 360 camera. My first attempt and capture of Mars, 1500 stacked frames from a 3 minute video. It's a shame I couldn't get the colour right last night. I've only done a handful of Jupiter. This is my best to date, 1000 stacked frames from a 4 minute video.
  15. Hello, I have loved the views through my 200p of jupiter and recently saturn. I just looked outside and realised in an hour or so I think I could point my scope in mars' direction. However looking at the apparent diameter of the planet it is only 0.04"! This time last year it was 0.14" ish I think. Its not going to reach that in 2013 whatsoever. My question is quite simply, at 0.04" and after sunset...any point in observing and imaging? Have a look at my flickr (http://www.flickr.com/photos/90652641@N04/) this is what I get with my 200p and stock barlow. Is mars going to just look like a star? Thanks, Dan
  16. Just to let you all know, on BBC2 right now is an Horizon special "A Mission To Mars".
  17. Hi All, After capturing about a hour of Jupiter videos to stack, I moved my sights on Mars and Saturn. Here im sharing my results of Mars... This was captured during the night of Jupiter opposition. Clear skies.
  18. Another planetary imaging session, this time with the C8 and the ASI120MC camera. This was the first time I tried to image these with the C8 so something of a 'test'. The log shows that I spent 25 minutes of valuable time in taking the rig down after imaging Jupiter and setting it up in a different position to image the other two planets. Next time I'll put it in a different position that will avoid having to move it. The altitude of Jupiter was about 20 deg, and the other two at around a roof-skimming 10 deg. Unsurprisingly (or otherwise) the results seem a bit better than with the 127mm Mak. In particular, I could easily see the Great Red Spot in the laptop live view. I feel a bit disappointed that Jupiter did not sharpen up more in processing. Here are three of the processed images (processed in Registax6 and should be the noninverted & nonflipped view). Again, not the world's best, but... I focused the camera on Spica. Mars has processed up quite sharp and, again, distinctly non-round (88% phase). But any tips on focussing? there are some apps in Smartcap, or maybe I should get a Bahinov (sp?) mask. I also recorded some .ser video which won't load into Registax for some reason- have to look into why.
  19. I haven't checked, but I am sure there are plenty of these around. I thought I would enter my daylight version as it is a little different. I followed the conjunction until it was lost in the glare and behind buildings, all in all a wonderful morning. Handheld at the eyepiece as normal for me using an iPhone 6 Plus. This is the last one I took that still showed all four moons despite it being 7.41am and relatively bright. Normal kit: Scope: Tak FC100DC (this is getting expensive...) Eyepiece: Need to check this! Will update when I have. Probably 12.5mm BGO at x59. Mount: AZGTi on Gitzo tripod Taken using Procam 4 and cropped and processed using PS Express, all on the phone.

  22. This morning I set out to get some images of Mars and Saturn, having got a good result with Jupiter a few nights ago. It turned out to be one of those occasions when almost everything seemed to go wrong. I struggled for ages in the dark to get the 8SE mount attached to the tripod (it has some white stickers on it now), the solar system align turned out to be inaccurate, and the laptop kept crashing. It became a race to get some result before daylight intervened. I aimed at Jupiter, and tried out Sharpcap's exposure histogram before turning to Saturn. The focus would not come good (as the stacked images confirm) so I switched to Mars, with the result shown below. The dark smudge appears in all six videos and seems to match the position of Syrtis Major. The Mars result looks encouraging, considering that it will be twice this apparent size at opposition. The altitude of Mars was about 10 deg. Equipment: C8 SE, ASI120MC, ADC, processed in Registax6
  23. I get up a couple of hours before dawn this morning and am greeted with a beautiful pairing of Saturn and Mars. Saturn looks beautiful, tilted perfectly in our direction, a bright peach orb sporting good detail including the Cassini division. Mars is definitely getting bigger and brighter, and is decidedly more reddish than Saturn. I can see a little detail now. I excitedly try out my Mars filter but don't see significantly much more detail (in fact, the overall tint is actually a bit distracting); maybe, it will work better as Mars gets closer). Jupiter, a little farther west, is an awesome, large, bright orb with striking belts, and the moons have a curious question mark-like configuration this morning. The regal Blue Moon is on its way to set, but I don't risk my "dawn" vision looking at it through the eyepiece. The air is pleasantly cool, nowhere near as chilly as some previous mornings (the weather here can't make up its mind if it's winter or spring). A little humid, so I pull out the dew shield. Well, what do you know, there's a developing high cloud to the west, threatening to interfere, lol (fortunately, it doesn't). I really want to see Mars and M22 together, less than a half degree apart, so that means I can see them in a telescopic view! Time to image! I set up the camera on the 127mm Mak and take several shots, this one being my favorite: And here is another pic taken several minutes earlier: Reggie
  24. I didn't think I was going to get to see this, as the weather was calling for cloudy skies. However, I rose at 06:00 anyway, got my winter clothes on, grabbed my binoculars and headed out into the cold and snow to see what I could see. Alas, I was rewarded! The planets were higher in the sky than I had anticipated, and the viewing, though a little hazy, was plenty good for seeing the conjunction. There were some nice views of the moon through the haze as well. A nice way to spend a morning. Did anyone else manage to catch a glimpse of this?
