I wasn't too sure what to recommend as I have my own preferences/bias. Also, it needs to be kept in mind they are new to the hobby and want to only spend a modest amount of money (if possible).
The two options which sprang to mind via technical specs would either be a long focal length achromatic refractor (i.e. 100mm x1000FL) which are made by Skywatcher or an 8 inch Dob (also made by Skywatcher). I would be able to lend them some eyepieces and I also have a spare tripod if also needed. So, the only real consideration is the telescope and thus bang for their buck as to what they will get to see of Mars
Consequently, I would like some feedback from those of you who have some experience with both OTAs as to what might be the better option to give them a good view of Mars
All thoughts/perspectives welcomed  |
A 6" or 8" Dob are my recommendations. Having owned both at the same time, I found the view of planets to be 'cleaner' in the 6" Dob, but a little more detail could be seen with the 8" Dob.
The EPs that come with them are barely acceptable, so I would suggest they they buy a good 7 to 11mm EP to enhance their views. Your probably have a good idea of the magnification that your local skies can support.
If your friends are only a little interested in Astronomy, they may prefer storing the smaller and lighter 6" in the corner.
If they would prefer a refractor, even the Skywatcher 70mm (900mm FL) will provide interesting views in this very favourable Opposition. Again, a better EP in the 6 to 9mm range is also recommended.
