Multi color images of clobular cluster TERZAN 4

These are roughly reduced images obtained with TRISPEC on UH88" telescope at 18th June 1999. The f/10 secondary mirror was used, and the field size is five square arcmin.

Optical and near infrared images of clobular cluster NGC6522

These are roughly reduced images obtained with TRISPEC on UH88" telescope at 19th June 1999. The f/10 secondary mirror was used. The images in the B, V, and I bands, or the images in the V, R, and I bands, or the images in the V, I, and K bands have been colour-coded blue, green, and red, respectively. The field size of the optical composit images (the first and second images) is five square arcmin, and one of the optical/NIR composit image is four square arcmin.


Optical to Near Infrared Spectrum of Planeary Nebulae NGC7027

Optical to near infraed spectrum of planeary nebulae NGC7027

This is roughly reduced spectrum of NGC7027, obtained with TRISPEC spectroscopy mode on UH88" telescope with the f/31 secondary at 5th Spectember 1999. The whole of the wavelength range of 0.45 to 2.5 microns are obtained simultaneously. The optical, IR1, and IR2 channels are coded blue, green, and red, respectively. The narrow 0.36" slit are used, then the spectrum resolutions are R=206, 210, and 535, respectively.


Optical to Near Infrared spectrum of Seyfert Galaxy NGC1068

Optical to near infrared spectrum of Seyfert galaxy NGC1068

This is roughly reduced spectrum of NGC1068, obtained with TRISPEC spectroscopy mode on UH88" telescope with the f/31 secondary at 5th Spectember 1999. The whole of the wavelength range of 0.45 to 2.5 microns are obtained simultaneously. The optical, IR1, and IR2 channels are coded blue, green, and red, respectively. The narrow 0.36" slit are used, then the spectrum resolutions are R=206, 210, and 535, respectively. The dips around 1.36 and 1.88 microns are due to incomplete correction of atmospheric transmission. And the dip from 1.97 to 2.22 micron is due to contamination with 2nd order light. (Note that this contamination problem had already been fixed by using germanium filter at December 1999.)
