Too bad about your camera. thanks for the advice regarding mine!

Hi Mark,


There is no advantage to the BF04 over the AF04 for planetary imaging.  

The BF series was the first "2nd generation" camera introduced by TIS  

at the time I purchased mine. The 21AF04 is the one to get today.


With regard to my ailing camera, TIS recommended a driver re-install,  

which I attempted (after a couple of days trying to find a Windows  

machine with firewire!) - but the camera is not found by the driver  

install app... it will have to go back for repairs or replacement.


best,

Alan

Hi Alan, I notice you`re using a DMK 21B F04 for your Jupiter &  

Saturn images. I was looking at this option for a DMK camera here in  

Australia;http://www.yorkoptical.com.au/ProductMenus/TeleAccessories/tabid/49/CategoryID/333/List/1/catpageindex/2/Level/a/ProductID/2590/Default.aspx?SortField=UnitCost%2cProductName

It`ll certainly be a few months before I can actually buy one but  

what do you think? Have the 21B`s any advantages over these? By the  

way did you get any useful feedback from The Imaging Source yet on  

your "broken" DMK?

Hi Mark and Ray,


Thanks for the nice words on my pictures... the good thoughts help

brighten this long period of lake effect cloud cover over the eastern

shores of Lake Erie.

Hi Ray, You`re right Chris Go has got it all happening! I`ve

marvelled at his images of the planets (particularly Jupiter) with

the simplest of cameras. I`ve wondered why he hasn`t felt the need

to upgrade to a 31 or 41 series TIS camera but given the results I

guess he`s happy.







Chris is a very talented and dedicated guy located in a great place

for planetary imaging. His targets are primarily Saturn and Jupiter.

The planets fit just fine on the small chip - there is no need for

anything larger than 640x480. The wider field of view of the 31 and  

41

series cameras might reach an additional outlying moon or two, but  

the

lower sensitivity from the smaller pixels in these cameras would be a

handicap. The larger chips are nice for lunar and solar imaging

though...


best regards,

Alan
