Lucky: τεχνική για πιο καθαρές αστροφωτογραφίες
Fred Ley απάντησε στην συζήτηση του/της Heal σε Λήψη αστροφωτογραφίας deep sky
OK, Sign me up, I 'll take it. Can't wait to see more results of this AO sytem with smaller instruments. Should be spectacular. -Fred -
Ένας μάγκας Έλληνας στο Astronomy
Fred Ley απάντησε στην συζήτηση του/της Γεώργιος Ταρσούδης σε Αστροφωτογράφιση - Γενική συζήτηση
Hi Anthony, Real nice photo spread. It's great that they want more of your images. That means more fun "work" for you with the telescope at night, but who cares, as along as you are having having fun. Lets see what they are going to do with you in their December issue. Can't wait to see. Keep on Trucking, -Fred -
Hi, I use the Meade variable polarizing filter. It has a thunbscrew on the outside that one can loosen which then allows for the one filter to be rotated against the second filter which is stationary. It works like a charm. Fred

Αστρονομικά εκθέματα στο Βρετανικό Μουσείο και όχι μόνο...
Fred Ley απάντησε στην συζήτηση του/της dimitris σε Λοιπές Αστρονομικές Συζητήσεις
Dimitri, Very images you have there. It has been quite some years since I last visited London. The museum that I want to go and visit again is the Science Museum. They had many old telescopes there among other interesting items. Yes, there is so much to see in these large museums that one is bound to miss something, which warrants going back a few times when visiting the city. Fred -

Μετεωρίτης 2,500 kg του Μουσείου Φυσικής Ιστορίας - Λονδίνο
Fred Ley απάντησε στην συζήτηση του/της dimitris σε Αστρονομία, Αστροφυσική και Κοσμολογία
Hi Dimitri, I wish that I had a meteorite that big in my collection. The biggest one I have is a 7,100.00 gram specimen from Campo del Cielo in Argentina. I should ask if I can locate a display case and bring the whole collection to the meeting in Patras, others may find it of interest. Fred -
NGC 281 PacMan Nebula in Cas LRGB 900x1200
Ο Fred Ley σχολίασε σε aristarchus για αστροφωτογραφία Νεφελώματα
Hey Anthony, I compared your image of NGC281 to the one that is displayed in Burnham's Celestial Handbook, Volume I, page 525. The image in the book was taken with the 13-inch telescope, in red light, at Lowell Observatory. Your image shows better detail in the nebula's structure and a few more stars than shown in the Lowell plate. Plus your image is in color and the fact that your image was taken with a CCD camera makes for all the difference in the world. Oh yeah, real nice image that you took. Fred -

Hey, Here's an even better image taken from the shuttle showing most of Greece and it has the ISS in the field too. The hi-res image is located at http://www.nasa.gov/images/content/187230main_s118e09467_hires.jpg Enjoy, Fred

Telrad NO! Quikfinder YES!
Fred Ley απάντησε στην συζήτηση του/της giorgosgr σε Λοιπά θέματα αστρονομικού εξοπλισμού
Hi All, There is a real neat gadget that one can purchase, which you lay on top of your sky atlas, to help locate sky objects in conjunction with the Telrad. One of our club members invented it and information on it can be found at www.actonastro.com if anyone is interested. It is called The Telguide. Steve's invention of the Telrad, a HUD device, is on my top ten list of "must own" items. I think I have three or four of them. If I can ever locate my slide collection, I have a slide of the biggest Telrad made. Steve used it as a "desk" as it was on a stand and one side would open as it was hinged. The large reticle actually worked. I always told him that it would look good on the side of the 200-inch Hale at Mt. Palomar. Naturally, if the Telrad can't be placed in a convenient place on an instrument, then it would be prudent to seek out an alternative. Just remembered that one can also purchase extra base plates for the Telrad and a Dew Shield too. Fred -

Θεωρείτε την ερασιτεχνική αστρονομία ακριβή ενασχόληση;
Fred Ley απάντησε στην συζήτηση του/της astrovox σε Δημοψηφίσματα
Hi All, Well, it really all boils down to one question, "what do you want to do". One can have a lifetime of fun with a 6-inch Dobsonian or if one wants to advance beyond that, well, the sky is the limit (along with ones wallet). -Fred -

Hi Everybody, Yesterday, while going through the current posting of images from the shuttle mission STS-118, old "Eagle Eyes"-that's me, noticed that through the shuttle window to the left of the crew member, one can see part of Attica, Makroniso, Kea, and portions of Kythnos and the lower portions of Euobea along with Petali Island. The direct link to the high resolution image on the NASA web site is... http://www.nasa.gov/images/content/186021main_iss015e22145_hires.jpg and the image number is ISS015-E-22145 taken on August 12, 2007. Below is the low resolution image, but the high resolution image is much better-naturally. Just wanting to share this minor observation with you all. Keep Observing, Fred

AstroVox T-shirt: Νέα εκτύπωση!
Fred Ley απάντησε στην συζήτηση του/της astrovox σε Λοιπές Αστρονομικές Συζητήσεις
Hi Andreas, OK, I'll grab one of those bad boys for my t-shirt collection. I like the "hot orange" look. Hey, at least if I ever get lost in the woods Search and Rescue will be able to spot me easily wearing the Astrovox Survival T-shirt. Over and out, -Fred -

ΑΓΟΡΑ ΑΠΟ ΕΞΩΤΕΡΙΚΟ!!!!!!! ΙΣΩΣ ΑΠΑΤΗ!!!!!!!
Fred Ley απάντησε στην συζήτηση του/της Δημήτρης Κουτρούμπας σε Πού και πώς να αγοράσω;
Hi Dimitri, One thing that I thought of is that if you are aware that the firm advertises in a British astronomical magazine, you can contact the magazine and inform them that an advertiser of theirs is behaving in a very unbusiness like manner. Perhaps they may be able to intercede on your behalf with a phone call to the firm. If I were a publisher I would certainly not want to carry firms that are disreputable. Also keep all copies of any correspondence that you have and write down any dates that you may make any telephone calls to the firm and the name of the person with whom you spoke with. Hope this may be of some help to you. -Fred
