  • Random Drupal Failures
    web site lately as I ve been getting random Drupal failures telling me it can t find settings php Utter nonsense the file is there permissions are correct and it usually finds it just fine So if you ve been confronted with a rather odd home page or link when navigating my site I apologize I think I may have worked around it but seeing how it pops up randomly

  • M31 with a Meade DSI Pro II - redux
    bloated stars are mostly gone What s left is probably due to crappy optics of the 50mm finder The calibration frames have also fully removed the dust shadows I didn t think about it the first time around but my source for the flat frames is an electroluminescent panel which doesn t put out much any IR so the flats may not have really been illuminating the focal plane the way the image was What s left that s annoying is those little bright squiggles They look to me like hot pixels that are not being fully removed by the dark frames I m not sure how but I m not sure what else to blame them on The final image above is from 120 30 second exposures The mount an AstroTrac TT320X AG was unguided and the images slowly drifted during the hour long sequence So after aligning them anything fixed in the focal plane like a hot pixel would appear to drift I used Maxim DL to process the images and there is a way to build a map of bad pixels which is will then remove and fill in from surrounding pixels but there is nothing obvious

    Nebula or something in Cygnus with a deep red filter which blocks most of the city lights and use it as a black and white image G2 41278 class g2image centered exactsize 800 After taking about two hours worth of images of the area around Sadr Gamma Cygni I thought I might try a few shots of M31 the Andromeda galaxy since at that time going on 3 AM it was high in the sky It was a spontaneous decision to take these with the Meade DSI Pro II since that was nominally the guide scope I was going to take the images using my Canon 350D with a deep red filter as I had been doing But there it was in the field of view of the guide scope so I centered the image and started taking frames There was absolutely no filter so the stars are bloated due to the unfocused infrared and contrast is compromised due to the sky background plus the telescope is a lowly 10x50 finder with the eyepiece removed In spite of taking dark and flat frames there are some remnant of dust spots and some dark pixels that couldn t be removed with

    have shortened the exposures of both the image and the flat field calibration frames to make sure I stayed in the linear region of the CCD s sensitivity It s also possible it was a temperature effect as the ambient temperature was changing during the night Overall I m pleasantly surprised Now to go dig that UV IR filter out of the closet and try again Roland Roberts s blog Log in to post comments Printer friendly version PDF version Navigation Calendar Gallery Constellations Messier Objects M27 The Dumbell Nebula Resources Astronomy Books Buying A Star Buying A Telescope Clubs and Organizations General Interest Imaging and Astrophotography Magazines Mailing Lists and News Groups Science Toy Suppliers Software Weather Information Tips and Tricks Roland s Corner Recent content About Copyright Search form Search User login Username Password Request new password Science Daily Mercury Mercury gets a meteoroid shower from Comet Encke Mercury gets a meteoroid shower from Comet Encke More Science Daily Venus The aliens are silent because they re dead The aliens are silent because they re dead More Science Daily Mars Antarctic fungi survive Martian conditions on the International Space Station Antarctic fungi survive Martian conditions on the International Space Station Rotation speed may be bad news for Red Planet pioneers Rotation speed may be bad news for Red Planet pioneers The aliens are silent because they re dead More Science Daily Jupiter New study challenges Jupiter s role as planetary shield protecting Earth from comet impacts New study challenges Jupiter s role as planetary shield protecting Earth from comet impacts NASA telescopes detect Jupiter like storm on small star NASA telescopes detect Jupiter like storm on small star Simulating the jet streams and anticyclones of Jupiter and Saturn More Science Daily Saturn Cassini completes final close Enceladus flyby Cassini completes final close Enceladus flyby How water escapes from Saturn Magnetic reconnection How water escapes from Saturn Magnetic reconnection Explosive energy in Saturn s magnetic bubble More Science Daily Neptune Evidence of a real ninth planet discovered Evidence of a real ninth planet discovered Mars to lose its largest moon Phobos but gain a ring Mars to lose its largest moon Phobos but gain a ring Simulation of 3 D exotic clouds on an exoplanet More Science Daily Uranus Jupiter bumped giant planet from our solar system This solar system isn t big enough for the both of us Jupiter More Science Daily Pluto Earth like planets have Earth like interiors Earth like planets have Earth like interiors Evidence of a real ninth planet discovered Evidence of a real ninth planet discovered New Horizons returns first of the best images of Pluto More Science Daily Comets and Asteroids Earth like planets have Earth like interiors Earth like planets have Earth like interiors Artistic space odyssey to broadcast people s messages to the stars Artistic space odyssey to broadcast people s messages to the stars New study challenges Jupiter s role as planetary shield protecting Earth from comet impacts More

    m the only one in the car and that becomes 22 passenger miles per gallon But as soon as the whole family of 4 piles in for a trip to the grandparents I m getting 88 passenger mpg Still not so good compared to that bus But I can comfortably seat 7 and have for field trips with the Boy Scouts at which point I m up to 154 passenger
