Flat Field Panels

HI there.
I did try to upload some photos of light box's i made ,
no luck so far i think the file size was to large, i reduced the file to a few hd k still no luck.
Regarding the Aurora flatfield panels, My experience with a single unit was poor.
To be fair to the Aurora panels, they will remove donuts and ccd defects,
I tested A home made lightbox and the Aurora panel, 20 of so flats combined.
Equipment Wo 80mm ed 0.8fr. canon 40d the big difference, Gradients in the finished image this is where the Aurora panel I had fell short.
I do have a photo tutorial on another pc Its in storage due to house move Ill try to upload photos i have again.
I found this to be a good read.
Regards Al

I use a single Aurora Flat Panel for both my scopes, I have the AT8RC which has an 8Inch Apperture, and I also use it on my C80ED which is an 80mm aperture, the panel I have is the "D 220mm (for Instruments up to 8")"

There should be no need to go any bigger if your scope apperture is 8" irrelevant of the sensor size, the sensor cannot see outside of the aperture so getting a bigger panel is pointless

I will need to get a bigger panel next year as I am contemplating getting an AT12RC as I now have my Skywatcher EQ8 Pro mount which is a real nice beast of a mount, very little backlash and very very precise

HI there , this guy is streets ahead when it come to light boxs

I just use a DIY box similar to what Al Costello posted in the last link. It seems adequate for my purposes though I'm not imaging to the same standard Simon is so I can't say if it would be ok for that level of imaging.

Here's mine: www.cademuir.eu/blog/2013/01/10/astropho...aphy-flat-frame-box/ I've put another diffuser in the middle there since then. Basically it's stuff from a craft shop and some led push button lights.
