Saturn

A shot of Saturn taken on october 2001 by an old TAL 110/800 OTA on a german equatorial mount + a 5x Barlow lens. Webcam Philips Vesta - mean of 35 images from an AVI file stacked and processed by Registax. Fulvio Mete (Italia).

 
Photo of the Sun was taken with the TAL-100R

A shot of a sunspot taken on last june, 16,2002 by a TAL-100R refractor + a 5X Barlow lens and + ND filters and an Herschel prism. Webcam Philips Vesta, mean of 10 images stacked and processed by Registax. It's clearly visible the granulation of Sun's surface and others interesting features of sunspot's umbra. Fulvio Mete (Italia).

 
Photo of the Sun was taken with the TAL-100R

Photo of the Sun on 28 Mar 2001 was taken with the TAL-100R on Tech Pan film with a 1/250 second exposure through a Baader solar filter. I used the afocal method with a Zeis Contaflex and 50mm lens combined with the TAL 25mm Plossel. This gaave an effective focal length of 2000mm and an image diameter of 18.5mm on the negative. The film was processed in Rodinal for 14 minutes and scanned with an HP Photosmart film scanner. The Zeis Contaflex with its vibration free leaf shutter is ideal for afocal photography. Using the afocal method solves the problem of the short travel of the TAL-100R focuser. Mike Gainer
 

 
Mars

I own since some months an old TAL-1 (110/800) optical tube, mounted on a japanese german equatorial mount. I take a photo shot with such an instrument to Mars, on June, 26, 2001 at a focal of 6500 mm using two barlows lens, by a Philips Toucam pro webcam. Median of 18 images: The result was duplicated in b/w to obtain a luminace image to use in the final, in LRGB mode. Are well visible the Cryse planitia and polar cap. Fulvio Mete (Rome, Italy).

Saturn occultation

Saturn occultation at the evening on 03.11.2001. Stefan Stumpf. Die Aufnahmedaten: TAL2M, Okularprojektion, 10mm Ploessl, Brennweite der Kamera: 115mm, Digitalzoom 2.5x, Belichtungszeiten ca. 1/15 Sek., Blende F2.8.

Photo of Saturn

Saturn. Rudolf Prinz (Germany): I made all pictures with the TAL2M 150/ 1200mm, afokal, i.e. with eyepiece in the telescope and with objective in the digital camera (Canon PS10) photographed. Equivalence focal length with Mercury, Mars, Jupiter and Saturn: 51m, otherwise 25.5m in 6,3 mm of eyepiece. I must increase with the camera so strongly, so that the field of the spotlight measurement is illuminated by the planet. Only then the automatic exposure works correctly. [Gallery>>]
