The finely-tuned universe has been equally suspect, to me. Now I have hope that these ideas are unnecessary. Any number of other universes probably are most probably not properly tuned to support life as we know it. I also find that the "final goal" of science to be possibly illusory to be quite amusing and satisfying.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7005807890186364346-1100119370534363095?l=nightsleeperinnm.blogspot.com' alt='' /></div>Bill Wallacehttp://www.blogger.com/profile/00448867412786888669noreply@blogger.com0tag:blogger.com,1999:blog-7005807890186364346.post-61219502044693103222011-01-09T16:00:00.000-08:002011-01-09T16:00:23.958-08:00<div style="TEXT-ALIGN: center; MARGIN: 0px auto 10px"><a href="http://2.bp.blogspot.com/_z2E91ASNpL0/TSpMFweuSTI/AAAAAAAAAuE/gHqYGkdy1dM/s1600/IMG_0035.JPG"><img border="0" alt="" src="http://2.bp.blogspot.com/_z2E91ASNpL0/TSpMFweuSTI/AAAAAAAAAuE/gHqYGkdy1dM/s320/IMG_0035.JPG" /></a> </div><br />Testing out my new Canon EOS Rebel T2i.

The target object was Comet 44P. I took two sets of 10 2 minute exposures about 36 minutes apart. The initial processing (alignment, stacking) was done using AstroArt 4.0. The initial astrometry was done using AstroArt against 5 UCAC2 stars. The final astrometry was done using Astrometrica against several thousand USNO B.0 stars. Astrometrica can also overlay the calculated positions of all known asteroids and comets in the field of view. 44P is in the middle of the field almost exactly as plotted. I found 7 others. Could be more.<br /><br />Left of 58416 there are two list so that you cannot read either; they are in the photo. 43620, 08184 and 30967 were found. Two were found near 08107.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7005807890186364346-2627657147770672289?l=nightsleeperinnm.blogspot.com' alt='' /></div>Bill Wallacehttp://www.blogger.com/profile/00448867412786888669noreply@blogger.com0tag:blogger.com,1999:blog-7005807890186364346.post-27855116484765815282008-11-10T20:38:00.000-08:002008-11-10T21:04:41.264-08:00<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_z2E91ASNpL0/SRkSQWaXFyI/AAAAAAAAApU/blO0LNaCGNE/s1600-h/ngc-891-aas.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 400px; height: 266px;" src="http://4.bp.blogspot.com/_z2E91ASNpL0/SRkSQWaXFyI/AAAAAAAAApU/blO0LNaCGNE/s400/ngc-891-aas.jpg" alt="" id="BLOGGER_PHOTO_ID_5267261311289857826" border="0" /></a><br />I took the above image on November 1 with my C-14/Hyperstar (F 1.9) and CCD-Labs Q-453. 10 frames at 30 seconds each.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7005807890186364346-2785511648476581528?l=nightsleeperinnm.blogspot.com' alt='' /></div>Bill Wallacehttp://www.blogger.com/profile/00448867412786888669noreply@blogger.com0
