Mercury will be anyway a black spot, as dark as it gets. Darker than regular Sun spots (which are just not as bright as the soundings, just a matter of contrast).

White light or H alpha is just a matter of preference, aesthetic mainly. H alpha will allow to see the typical structures seen in that wavelength, while white will not, but will look more "natural".

If you are actually thinking in shopping, go to whatever is cheaper if you don't really mind.

In any case, be extremely cautious and use the safest products. You got only 2 eyes and the sun can burn then in fractions of a second.

Since I've 2 small kids, I've banned any kind of instrumentation for Sun observation. Prohibited to myself until they are 100% conscious and responsible.

Cheers

Hi, steve! I've shown these before, but both work fine >>> of course want to image the sun days before to make sure you are getting otherwise good images. Use the identical logistics, equipment, and settings for the transit. Mercury is kinda small.   Tom

I used my old Sears refractor and an old 1 meg eyepiece camera to get these images.

Depends on what you want to see with the planet relative to the features of the sun, which also matters based on image scale.

 

If there were sunspots, proms, big palge areas, I would want to do HA.

 

But, more likely, there will not be any of that. So I might do white light a little more, and just go with a high res photosphere approach so that we can see the planet relative to convection cells.

 

I'll likely try both. Seeing will be the great limit, if weather even allows me to see it.

 

Very best,

Hello
I think that in white light it is more natural.
but both can give a very interesting result.
sunnyday to all of you

First contact might be more interesting in Ha.  I intend to try.

Me too. I'm sure our chances are great for clear skies in November in Cincinnati! smile.gif

I scheduled the day off months ago thinking the odds aren't great.  If there are sucker holes we may just have enough geographic separation between us Warren to merge our images and create a complete sequence.  Eyecrazy.gif
