Hello Alex!

First of all,you have to clear up to us,what kind of observation you want to do!If you want to make a serius observation of Mars-in high magnification-you need not only a dark sky,but certainly an exellent seeing and clarity of the atmosphere!And this is the difficult point!

Most Greek amateur astronomers are not interested in very high level-and high magnification-planetary observation.They prefer to observe,during the astroparties,usually Deep Space Objects,in d a r k skies with good but not necessarily,e x e l l e n t seeing!

So if you need exellent seeing,you have to go to places,where seeing has been checked and counted by specialists,like Mount Helmos,or Mount Skinakas in Crete(where is the Observatory of University of Crete).

Because you will make a big journey,you have to decide exactly what you want!

And of course it will be much better to go for observation,with Greek amateurs astronomers in the r i g h t place!

Mars is my priority. All the same Great confrontation is rare, and deepsky every year the same. Therefore, in the program I have an obligatory visit to the Helmos Observatory. From the deepsky I am interested in the area of Sagittarius, it is low in our country. Well, it's also very interesting to meet local amateur astronomers.

Without your advice, it would be very difficult for me to be guided! And now I know a lot of useful information from the Greek amateur astronomers.

Exept Mount Helmos,you have a second choice,maybe better!

There is in Crete,southern than Peloponnese,near to Heraklion.Ιs at the Mount Skinakas(1750m),where the Obvervatory of University of Crete.The clarity and the seeing are exellent!The scientific study and measurement of the atmosphere's clarity and seeing,has been done by the famous Max Planck Institute(Germany).The seeing is guaranteed to be good!(Unless the weather goes mad-it'll be very unusuall this period(August) in Crete).

The observation area is much bigger than Helmos,more level and the wind less strong!It's much easier to go there by car,than Helmos(2340m)!You can see these areas using the Google satellite maps!

I dont know if you choose Peloponnese for personal reasons,or just for observing...

There are people in Heraklion,amateur astronomers who observe there,in Skinakas, and they can advise you,or maybe go for observation together.

Of course,first of all,it's better the friends ''vtsamis'' and ''Vensius', to confirm if the clarity and the seeing is really exellent(not only dark skies) at the places they invited you for observation.

Then you decide what you will do,ok?

Dear Alex,I simply inform you that ships traveling from Athens(Piraeus in particular) to Crete are very large and very safe!

Any way,contact the friends ''vtsamis'' and ''Vensius'' and ask informations about the seeing,if it is exellent at the places they invited you to observe(not only dark skies and good atmosphere's clarity)!

I wish all the astronomical team in Peloponnese,to organize an observation specifically for Mars in an area with exellent seeing!

I wish you the best!

I'll think about Crete. But I'm limited in money. And refueling cars back and forth will be quite expensive. I will decide already closer to August.

Thank you for your wishes and information! Your advice helped me a lot!

Hello Alex!I'm happy to help you!

I hope you find the best solution!Don't forget to check out the places that are suitable for observation,especially Mount Helmos,using the google satellite maps(better the 3-D version)!

I mean you use the google 3-D satellite maps to see the mountains you are propably going for observation.To have a good picture of the landscapes will you meet there...

Also contact the friends who invite you to Peloponnese,and ask them if the ''seeing'' is exellent for observation using high magnifications!Using your 254mm=10'' telescope(and the Baader Moon & Skyglow),you can see Mars with over 350x,400x,even 450x magnification,if clarity and seeing are exellent!Only then will you see unbelievable details on the surface of Mars(I have this experience)!

I already checked Helmos on Google maps. I saw all the photos, I found out where to watch the weather. So I already know where to go.

I am confused that I have eyepieces 3.2 mm and 2.5 mm TMB Planetary 2. And in them the image is not the clearest.

You can directly in this thread make a list of those who will go to helmos in early August. I will certainly be very glad to go with someone in the company.

I dont't know if some amateur astronomers will want to go to Helmos!I don't know if they are interested in making a serius observation of Mars...Because I will not be in Peloponnese,I don't know what will happen...You have to communicate with 2 persons,who invite you for observation in Peloponnese:''vtsamis'' and ''Vensius'',and ask the details(sent personal message-''πμ'').

About your eyepieces,if your telescope's focal length is 1200mm,like mine(D=254mm,F=1200mm),then with 3.2mm eyepiece you have a magnification of 375x,and with 2.5mm you have 480x!These magnifications(especially the 480x)are very high,and to see a clear image you need e x e l l e n t clarity of atmosphere and seeing!The theoretical limit(the maximum acceptable magnification) of our telescopes (D=254mm) is 2x254=508.But it's very difficult to have at 500x clear image!I had only one time until 480x,observing Jupiter in a very clear sky!

So you need,exept 2.5mm and 3.2mm,larger focal length eyepieces,to give you smaller magnifications!To be able to see the sharpest image,that the state of the atmosphere in the area you will observe,may allow you...

Because of this I told you about Helmos or Skinakas in Crete...There,the clarity and the seeing-during the summer-are usually exellent!You will have more than 300x magnifications!At 375x,and 400x,you will see many details on Mars!Unless there are sandblasts on Mars that period you'll observe! #-o

Hi, I 've just found a 2010 thread in astrovox

https://www.astrovox.gr/forum/viewtopic.php?t=12805&highlight=sqm

 

where you can see SQM measurements for some observation sites in Greece, including Mt Parnon, Mt Skinakas, Mt Helmos, etc

I hope they are useful.

Attention!

The SQM indicates the maximum mag,so how dark is the sky, N O T the ''seeing'' of the sky!

''Seeing'' is measured using special instruments,or by direct observation using the method of ''non-focused stars''!

In practice you can see the state of clarity and seeing,observing planets at high magnification!

Alex needs not only dark and clear sky,but exellent s e e i n g for planetary observation!

And what places in Greece is worth seeing? I certainly know about the Acropolis and about the monument to Leonid (one of the great people in history, Alexander I do not consider great. He just got a great people). But I would like to learn from local about interesting places that you can not find on the first pages of Google.

I had never specifically asked and read about the countries I went to in order to get a full and unbiased impression of the country. Although of course I knew a lot)) But Greece is a special case, it is the cradle of civilization. I do not want to miss interesting places.

And how do modern Greeks refer to ancient Greek culture? Do you consider yourself to be the direct descendants of the ancient Greeks or a modern nation living on this earth? Well, as modern Egyptians, who have little in common with ancient Egypt. This is certainly a bad comparison, but still))

P.S. I live in a city with a Greek name. Not only that, in the area called Arcadia. We have a Greek religion and I have a Greek name.

Dear Alex,there many interested places to visit in Greece,antiquities and many beautiful natural landscapes!

The Egyptians,mixed with Arabs,because of this they have very little relation to the ancient Egyptians.

Greeks,on the contrary,the most of us,we are natural descendants,of the ancient Greeks,with their virtues and their defects unfortunately...We have maintained our basic national intentity for 3000 years(exept religion,we are Orthodox-Christians-90%-since 2000 years),but in the last 30 years we have begun and lose it...

Unfortunately,in the last 30 years we have became worse,due to the current materialistic way of life...

However,especially in the Greek province,despite the deterioration of our consciousness and character,brought by the modern Western way of life,we remain relatively warm people,with love,less than in the past,of course...

Especially now,due the economic crisis,Greeks are more nervous,more stressed,more pessimistic,but we remain hosts(philoxenia=hospitality is a greek word),and the oldest of us,philanthropists,we continue to be interested in our fellow citizens.

The opinion everyone has on religion depends on his experiences...but we can not discuss it in a public astronomy forum...only through a personal message,ok?

For more information on the places you can visit in Greece,you can see the website of the Greek Tourism Organization: http://www.visitgreece.gr

I'm happy for you Alex!Finally for me,this summer,Mars was not a good target for observation,due to the sandstorm.I'm glad you ejoyed the event in Parnon!

We will have an appointment with Mars in 2 years!I hope there will be no sandstorm like this year!

Until the year 2020 comes,I wish you enjoyed your observations Alex!
