PN BIDZ-1 and M104

[tornado33]

Hoghy and I stood in my backyard watching cloud threaten, however when it got dark it dissapeared and the transparency improved markedly. So I set about imaging this unusually named planetary, its not even in the Argo navis catalog, I came across it in Star Atlas Pro.

BIDZ-1 in Centaurus, 90 mins ISO400. LPS filter. Modded 350D 10 inch f5.6 newtonian.
Full res. version here (http://d1355990.i49.quadrahosting.com.au/Scott/BlDz%201%20x9x10minsiso400lpsmod350 d10inch11degc_filtered.jpg)
Star Atlas Pro reports it as 82 arc secs in size with H beta mag of 14. Also known as PNG293.6+10.9. I imagine it would be a good challenging visual target for the visual observers.
Spitzer images of it here (http://crescent.astro.illinois.edu/projects/spitzer-pne/BlDz_1_img.php)

Then I removed the filter and had a go at M104. Wind had risen a bit buffeting the scope but subs didnt look too bad so kept on with it till quite late.
M104, 11x10 mins ISO200. Unfiltered. Modded 350D 10 inch f5.6 newtonian.

Temp a chilly 11 degrees or so. Both pics used Baader MPCC coma corrector and were off axis hand guided.
With the weather of late have gone from imaging famine to imaging feast :)

Scott congratulations for getting off the well worn beaten track with BIDZ1. I did observe this visually from Leyburn back in 2004 using a 37cm and OIII filter. My notes say it was discovered in 1975 by Blaauw & Danzinger and is at a distance of 4900 light Years. It is in the revised Hartungs as object 490 and also known as ESO217-11. The paper below refers to its discovery.
Very nice image indeed.
Actually if you go to the Argo Navis site and look in User Catalogues you will find a catalogue I made up years ago called the Leyburn List (if its still there). It has many interesting mostly far Southern Objects I found including this one.

Thanks for that Peter. I might even be tempted to throw on the lps, UHCS or 0III filter on an eyepiece and see if I can see it visually.

Great shots Scott. You have the setup working well.

Thanks for that info again too Peter - fascinating to hear what exploits people have had in the past. Technology continues to take us in unexpected ways (unless you planned to be an automated supernova hunter back then that is....!)
