Let us know when all that stuff comes up for sale (but we hope that it
doesn't!).  Walter

Tony, I have the double stacked 40MM Coronado solarmax scope.  I have had
people tell me it outperforms the 60mm single stacked.  I have been very
please with its performance...at the time it was all I could afford and even
then I spent about 3500 on it.  That was an extra 1 grand to get the extra
stack.  But I used it at the MASP this past year and also at Coinjock and it
did great.  Especially if you cover your head with a black cloth.  I usually
mount it with my Tak scope at star parties.

 

If you can afford it and want to see lots of detail, get double stacked if
you can.  There was also a single stack 90mm Coronado at ECSP last time, and
more than one person told me that mine even outperformed that.  Brighter
image it had, but I think mine actually still shown more overall detail.  I
also, like Robert was very impressed with the Lunt scopes, both visually and
mechanically.  Quite a layout of money either way.  But if I had the money
to buy anything like this now, and really was that interested in the sun, I
would seriously look at Lunt.

 

I can't tell you much about imaging with them.

 

If you are mainly interested in just the transit then you don't need a
H-alpha , but they are nice!  

 

If I don't get more observing in soon, I am gonna have to start selling some
of my stuff!  allen

I am curious if any viewed the last transit of Venus or an Annular eclipse,
and what equipment people may have used and would recommend. ( at risk of
starting a never ending thread I know, but we are an astronomy club, why
not? )   A few opinions would be great.

In just a few months we have an Annular Eclipse in the west on May 20th- (
which I am seriously considering flying out for since it will be over parts
of the west I know very well,  the Black Rock Desert all the way to
Farmington NM, Chaco Canyon and ABQ. Lots to choose from! )   

And the transit of Venus on June 5th. ( heck, I may fly out west for both,
or the NC mountains sound nice. or how hot will Medoc be in June ?) 

Considering the rarity of all of this I am considering getting a more
serious solar telescope.   I do already have a white light solar filter for
my 6" maksutov-newtonian ( levy comet hunter ), which gives me decent white
light views of sunspots, but that's it.

Not bad, but should I consider more?  A 60mm Coronado?   A 60mm Lunt either
visual or imaging? Something else?  

And are the views really that much more awesome?  ( a few thousand dollars
more awesome than what I have now! ) 

Should I get a double stack filter if going that far?  

Will the general solar viewing and imaging w/ an H-A telescope be quite fun
if you are a solar enthusiast? ( i've read this book, Fundamentals of Solar
Astronomy
<http://www.amazon.com/Fundamentals-Solar-Astronomy-Scientific-Astrophysics/
dp/9812382445>   so I'm somewhat into it. ) 


( one more dangerous side road -  was also considering a better mount for
maybe catching a picture or two with a canon DSLR - currently using a good
alt-azimuth, was thinking about the new meade LX80, or maybe the IEQ45 ?
Maybe I don't need that much mount for 17-20 pounds of telescope, and less
w/ 60mm solar scopes at 8 - 10 pounds. )
