The first dome, the northern of the pair, which I refer to as the North Dome, was built in the summer of 2006. I designed and built the building myself, though the shape of the "dome" is most definitely inspired by the WIYN Observatory on Kitt Peak,
Established in 1926, Beverly Hills (zip=21214) is a small subdivision of Baltimore, Maryland, a 13-block postage stamp in the city’s northeastern section, roughly four miles from downtown. No movie stars, few if any swimming pools, but home to Beverly Hills Observatory, a privately-owned astronomical observatory engaged in research on a variety of topics particularly relating to stellar astronomy. On almost any clear evening the twin 16-inch telescopes are engaged in gathering photometric and spectrographic data of cataclysmic variable stars, eclipsing binary stars, Wolf-Rayet stars, massive young stars with vigorous stellar winds, and just about anything else that piques my interest. Welcome!
For most of the month of June I gathered photometric data for the star OV Boötis (OV Boo), an eclipsing cataclysmic variable star with a very short orbital period. The data were acquired using the #2 16-inch with an SBIG ST8xme camera and clear filter. The images were calibrated using BHO_ImageCalibration, and reduced using the […]
Presented here is a description of a program for time series photometry based on the techniques of optimal extraction. The program is fed a list of images to reduce, then the user indicates the program star, up to ten comparison stars, and a psf model star. PPX then finds stars in each image, determines object matching from one image to the next (shift, scale, and transpose) using similar triangles, then uses the image mapping coefficients to … read more >>>>> about PPX: An Optimal Extraction Program for Time Series Photometry
A set of throughput tests was conducted using a Meade 0.63x focal reducer and a Celestron 0.63x focal reducer in concert with a Santa Barbara Instrument Group (SBIG) Self-Guiding Spectrograph (SGS) and a Celestron 14-inch Schmidt-Caseagrain telescope. The results of this analysis would suggest that one should NOT use focal reduction that would produce an effective f-ratio of less than about … read more >>>>> about Relative Throughput Tests Using Focal Reducers with a Santa Barbara Instrument Group Self-Guiding Spectrograph
