Whichever of my "too many" scopes is usable from 40mm to 400mm.mm,

Mars will be very close come June/July/August. I will be using a 120mm f/8.3 achromatic refractor, with a 90mm aperture mask. What telescope will you be using for this rare proximity of Mars? 

I'll look at Mars with whatever scope I happen to be using at the time.  If I recall correctly for northerners this won't be a very good opposition, with Mars positioned somewhat low through excess air-mass.

 

Best,

 

Jim

My Cave cassegrain and D&G refractor. Can't wait!

That framing work is first rate.

 

Nice classical glass too.

 

Best,

 

Jim

5" Meade ETX 80 + Baader Hyperion Zoom and opt to get this one to about 250X

 

 

Ed:

 

I'm guessing you meant to write ETX-125? 250 X in a ETX-125 is reasonable. 

 

As a comment: in my experience,  Mars is not kind to fast achromats,  achromats do not focus red and with Mars being very reddish,  that means there's a lot of unfocused light.  I think a filter of some sort is a necessity to view Mars in a fast achro.

You are right John, the ETX 125, not the 80.

 

 

I don't think Mars is going to get higher than 25 degrees for us in the NY city area.

I'll soon have my 150mm Mak-Cass on order and I hope to use that scope for all of the planets this year.  That and my 10" dob!

Probably won't be that good here 42 N, but Mostly my C8 with the Zwo224 (perhaps also with the ES102 just to compare). I remember in 2003 showing my neighbor and a long time friend the ice caps on Mars and the friends stills remembers how cool that was.

I've probably repeated this answer a half dozen times in other threads asking a different version of the same question.

 

I'll be using the exact same scope I've been using since 2008, which is in my signature block and is seen below. The ONLY scope I ever use.

 

The only difference is that I might add an aperture mask, depending on the sky conditions.

Primarily my 4" Apo...and a little with the 6" Apo.



This was the last time I viewed Mars for any length of time. Really excited to view it again this year. There is something about viewing land structures and polar caps on another planet that just sends shivers down my spine!

What does the aperture mask do for you/the view?
