IMAGES FROM GRANGE OBS.

Images from Grange Observatory



Jupiter 2015
Jupiter imaged with the Vixen NA 140 refractor and the QHY5V monochromatic camera on March 8th, 2015 (CCD sampling 0.36 arcsec/pixel); RGB footage processed with Registax 5 and IRIS programs.


Sun 2013
The Sun imaged with the Vixen NA 140 refractor on June 2nd, 2013 in the Ca II H line at 397 nm (0.30 arcsec/pixel CCD sampling, the footage best 600 frames out of 1200 were stacked using Registax 5 and post-processed with IRIS using unsharp masking and Richardson-Lucy deconvolution).


Sun 2013
The Sun imaged with the Vixen NA 140 refractor on March 10h, 2013 in the Ca II H line at 397 nm (0.62 arcsec/pixel sampling, the footage best 300 frames out of 600 were stacked using Registax 5).


Saturn 2012
A Saturn picture obtained with the Vixen NA 140 refractor on June 14h, 2012 with a Clavè Plossl 6 mm eyepiece and a Philips 900 NC webcam (0.23 arcsec/pixel sampling, the footage best 50 frames out of 100 were stacked using Registax 5).


hale-bopp 1 hale-bopp 2
Comet C/1995 O1 Hale-Bopp photographed on the evening of 6/4/97 left with a 200 mm f/3.5 telephoto lens and right with a 50 mm f/2 piggyback the 0.3 m telescope of Grange Obs; both images have 5 minutes exposure on 1000 ISO color film.


hale-bopp 3







Comet C/1995 O1 Hale-Bopp imaged at dawn of Feb. 8, 1997 with 0.3 m telescope and CCD camera SXL8 at the Newton focus (focal 1200mm, integration time 60 seconds).










The Orion nebula (M 42) as seen through the 0.3 m telescope with a 60 second exposure of CCD SXL8. Image taken in the early hours of Oct. 23, 1996.


M 8







The Lagoon nebula (M8) in Sagittarius obtained with the same instrument and exposure time as above in the evening of Jul. 26, 1997.


M 27







Dumbbell nebula (M 27) in Vulpecula registered with CCD SXL8 and 5 minutes exposure.


asteroid  1980 PA






The magn. 13 asteroid (3908) 1980 PA has left a clear trail on the image taken in Oct. 18, 1996 with the 0.3 m telescope and CCD SXL8 (5 minutes exposure starting from 21:18:00 U.T.). Its distance from Earth at that time was only 0.068 A.U. (about 10 millions km, 30 times the Moon's distance).

The solar eclipse of Oct. 12, 1996: image taken at 14:28 U.T. with a 400 mm f/7 telephoto lens and CCD Electrim EDC-1000 HR (753x488, 30 msec exposure). The eclipse percentage in diameter at that time was 0.52, as calculated with the above formula.
