The art of lining up the lenses, focusing, the effects of strong winds on the ground and right up through the atmosphere. The ubiquitious Ebay $55 spotting scope is quite a remarkable instrument. The comes issues of the steadyness of the mounts and decent camera mounting. For a basic lunar telescope - these are pretty good and far better than nothing. BUT for planetary observations, much more powerful magnification and rock solid mounts are needed.

How Powerful Of A Telescope Do You Need To See Mars?
Looking for a telescope to view Mars with enough power to see its surface features? Telescopes of apertures of 5 inch upwards to 8 inch in a reflector telescope are ideal to see surface color, polar caps, and noticeable dark features of Mars (as well as the moons and bands of Jupiter, and rings of Saturn).

Mars through 8 inch telescope will give you great views but don’t be too disappointed if you have something smaller. You should still see major dark surface areas and polar caps of Mars with a 3 – 5″ aperture.


If you are wanting to see clouds you are going to a need an 8 inch reflector and upwards to 14 inch, which isn’t the most practical.

Guide on the webpage.......

The above is a guide that includes what you are likely to see of Mars through telescope observations based on aperture size. What you actually see, however, will depend on a few variables, including light pollution, quality of optics, and atmospheric conditions.

You may be wondering about power (magnification).

Magnification Of Telescope To See Mars’ Features
Magnification is how much a telescope enlarges its subject. You get this based on the focal length of the telescope and that of the eyepiece you’re using.

Magnification = telescope’s focal length ÷ the eyepiece’s focal length.

Mars is a small object and contrast is not an issue so you can go full throttle with the magnification.

This means use the highest useful magnification of your telescope.

As a guide, you can easily work out this maximum useful magnification from the aperture size…

It is expected somewhere within 50× the aperture in inches (or 2× the aperture in mm) of the aperture. Be aware that this is the optimal amount and the amount decreases with declining atmospherice conditions. So include a bit of leeway in this case and try for 25x to 30x the aperture size.

I cover more on this in My Best Telescope For Viewing Planets Buyer’s Guide.

So the power of a telescope to see Mars’ surface depends on the aperture size of your telescope as well as the eyepieces and focal length of your scope. I hope this helps.

FAQs
Can You See Mars Without A Telescope?
Yes, you can see Mars at night without a telescope. It appears as a bright star with a reddish tinge. But you’ll need a telescope to see any features of Mars surface (or at least a suitable set of binoculars).

Just How Big Is Mars?
The visual included above shows the size of Mars with respect to Earth. It is about half the size of Earth.

Does Mars Have Rings Yes Or No?
No, unlike Saturn, Mars is ringless.

Can I See Mars Through Binoculars?
Yes, you can see Mars through binoculars for astronomy. To find out more see my article about selecting the best astronomy binoculars. I also cover tips about using binoculars for astronomy.

In Closing
The red planet, Mars, is a close neighbor to Earth. You don’t need a telescope to view Mars. Visible with the naked eye, Mars appears like a star with a reddish tinge in the night sky. Viewing Mars through a telescope, however, reveals its reddish surface marked by dark regions and if you time it right, you may see at least one white polar cap.

I have neither a telescope nor a pro model phone. I took these earlier this morning;

Ummmmmm chasing the really brilliant photos - or seeing really brilliant images, is a bit of a good obsession. It's healthy, makes you smarter, and you have to temper your enthusiasm and excitement with patience and the practical realities of life. When you can see the moon, through even a relatively low cost ($55) spotting scope, the whole dynamic changes..... Like most of the "pretty good" images are mine, but the really good photos are from bigger earth and spaced based cameras. Earth photos are both having good enough telescopes, very steady, solid mounts, and the better atmospheric conditions. - both at the ground, and up through the atmosphere. This is good. --- https://www.ebay.com/p/1483973066 ------ This is better ------ https://www.ebay.com/itm/231705368718 ------- The spotting scopes are brilliant, they have excellent magnification, they are reasonably rugged, and very portable.... - BUT beyond this, you really need to start researching different types of lenses, telescopes, recommendations and fit for purpose units. Also rigidity in the mounts becomes a real issue. Having the telescope blowing around, so the ends move by 1/10th of a millimeter, becomes 100,000 Km of jiggling at 50 million kilometers. Starting at the lower price point and thinking how to improve things and why, makes you smarter, than throwing lots of money at things that are already sorted out. Plus compromises and work arounds need to be made, because a very portable telescope with cheap mounts, can still produce great pictures, compared to a very big and expensive and heavy telescope that is hard to move, if you strap it to a steel flywheel from a car motor, and put it on a solid picnic table in a national park.... There are issues of light pollution, air turbulence, etc., and cheap horrible camera mounts for phones, vs a fixed focus digital camera with digital only zoom, and a friend with a lathe and a bit of aluminium and some rubber o rings etc.

And there are issues of camera optics and light amplification and sensitivity. The CMOS chip, has an infrared filter over it, AND they are brilliant all around cameras, but the cameras that have really big light chips, with very high densities, and manually programmable operating systems than can give very long exposure times, all start to make this a bit more complex. Also scopes can need tracking systems for long exposure times, as the earth rotates once (360* degrees) every 24 hours, So If you point your scope and it's camera at a planet, for 10 minutes, that is 24 hours x 60 minutes = 1440 minutes -: 10 = 14.4 degrees. Your camera - if it does not have tracking - the planet has moved kinf of totally out of view. See if you can join an astronomy club and try the telescopes at a few facilities like the universities, the clubs and the big deep space observatories.

And with very low light levels -aim for contrast by going to the darkest areas you can find, as the street lighting, bouncing back into the atmosphere and hitting the pollution and dust etc., makes the light level of the air much brighter, compared to the dim object in the nigh sky.

The first ever proper galaxy I saw with the spotting scope was the Orion Nebula. There is a row of three bright stars, that depending where you are and can see, well in this picture, the slope at 45*, down, to the left. And just below the middle bright star, is a vertical row of smaller stars - the center star is a full colour galaxy composed of two stars and various gasses and dusts and all that - and yes you can see the spiral arms of the galaxy and it's in colour.... This is about the optical limits of a good cheap $55 Ebay spotting scope, in a dark area, on a clear windless night. . BUT once you start to jump up in light gathering power (Galactic cannon sized telescopes) and magnification, you automatically go from a handful of easy to see stars in the night sky, to BILLIONS OF THEM.... https://cdn.britannica.com/09/....91709-004-E9516081.j

@Life_N_Times_of_Shane_T_Hanson: Where did you take the photo? Somewhere in the remote part of Australia?
