Mars...any point?

Recommended Posts

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

In a word, no. You might just get the tiniest hint of some sort of detail but I doubt it. Better to wait until back around again.

It will not look much bigger than the GRS so you will not see too much detail !!

Darn, thankfully there is not a shortage of things to see before mars is back around!

If I can ever be bothered to set it up at this time I may have a peek for the sake of it anyway.

Wow that really puts 0.04" into perspective aha!!

Hi Dan,

Some really nice images in the flickr album and good to see what can be produced with the same equipment I'm using (something to aim for anyway!).

I think the next good oppurtunity for mars is 5 years hence:

  • Dec. 24, 2007 – 88.2 million km (54.8 million miles)
  • Jan. 29, 2010 – 99.3 million km (61.7 million miles)
  • Mar. 03, 2012 – 100.7 million km (62.6 million miles)
  • Apr. 08, 2014 – 92.4 million km (57.4 million miles)
  • May. 22, 2016 – 75.3 million km (46.8 million miles)
  • Jul. 27. 2018 – 57.6 million km (35.8 million miles)
  • Oct. 13, 2020 – 62.1 million km (38.6 million miles)

Otherwise I think the options are limited to a 5x or stacked barlow or buying a nice big long refractor. Still got to be worth a go and will look forward to seeing some images!

Yeah, fingers crossed then that 2018 doesn't prove to be the wettest/cloudiest on record!

Any opposition's a good time relatively speaking though. Indeed the 2018 opposition actually looks awful for us in Britain as Mars will only rise about 12 degrees above the horizon!

Thanks Catab, I was going to look at this is Stellarium tonight but now I'm just too depressed :(

I have yet to view Mars in my 4inch mak but probably best I keep my expectations low when I finally get the chance. :smiley:

The closest oppositions are always in the summer so if you really want to get a good view of Mars then going into the southern hemisphere is the best option.

Mars is currently 4" not 0.04" - even Hubble couldn't see any detail at 0.04" ;)

      This planetary grouping from 20th March around 5.30am shows Saturn to the left with conjunction of Jupiter above & Mars below, sharp eyed may also see...  Io, Ganymede & Callisto in a string just right of Jupiter.

      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.

      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.

      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.

      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).
