Dear Jean-Philippe,
I am a SNO-T user for more than one year,
and I am VERY interested in sharing experience.
Most of my observations are also "backyard",
more precisely, balcony observations.
(But I also have some Atlantic observations taken from
a small boat). These include
Sun artificial horizon altitudes, Lunars,
and star-to-star measurements. And few Sun measurements
in the Atlantic.
And also all sorts of errors adjustments and corrections.
So please send me your numbers.
I am interested in any numbers from index correction to Sun
art horizon altitudes
to Lunar distances.
Also include the year made and factory correction table of your SNO-T.
> Here are the results of some measurements
Where are the results?
I found no attachment in your message.
(As I understand the general policy of this list is to discourage
attachments. I think this is a wise policy.
Can you include your numbers in an ordinary text message?
Or send me the attachments off the list.
(In general I prefer not to read attachments written in proprietary
formats of Bill Gates and Co, but .pdf is OK.)
But if you don't know how to (or don't want to) send anything but some
Bill Gates Windose format, like Excel or MS-Word or whatever,
I will make an exception from this general policy;
I have a special Windose computer for this:-)
> All sights were taken with the 6x Astronomical (inverting) telescope.
I find this inverting scope very much superior to
any other scope I ever tried.
I am not so much satisfied with "the rest" of my SNO-T:-(
(Especially with the "trommel").
> I have practiced less with the SNO-M
May I ask you why did you buy an SNO-M after an SNO-T?
(It is a general agreement, even among the Russians) that SNO-M
is by far inferior to SNO-T).
> The SNO-T allows a drum scale reading of 0.1' (do you agree?)
Absolutely. But unfortunately, my SNO-T precision is very far from that.
> in order to find GMT Time and had very widespread results, from 18s to a

Lunar distances are tricky. Very much depends of how large the distance
is.
But I want to see your star-star measurements with SNO-T first of all.
(And I am ready to send you hundreds of my observations with SNO-T
and all other info about it I have).
Alex.
