Trying to figure out camera specs

[Kilohertz]

Hi all,

I am starting to assemble my first "modern" (non film) telescope and am wondering about frame rate and such. I have a machine vision camera which has a 5MP CCD which is capable of 4 fps at full res and 7fps fastest. I have read in various tutorials that 50fps would be satisfactory.

Just curious why such a high fps is required if we are making 30s - 10 minute or more exposures?

Thanks!

None for long exposure imaging. But in planetary astrophotography it is important and 50fps is middle of the road to the best out there, not me, I struggle to get 10-20fps, but then again planets are not my passion.

BTW, MP's are of little importance either, pixel size and frame dimensions are of greater concern, first defines your resolution in arc-seconds/pixel, and the second defines what will fit in the frame.

However, there are sooo many other factors that it almost boggles the mind when first getting into imaging.

Good luck,
Steve

G'day kilohertz, I think this is your camera correct?

https://www.adept.net.au/cameras/avt/oscar_f510.shtml

Info says it does support region of interest, which is a crop framing option that boost frame rate, that is the ideal setting to use when imaging planets, max fps is 24 at 320x240, depending on your magnification the 640*480 at 13 fps might be a better setting for frame larger planets like jupiter, 15-20 fps is very doable to produce an OK image, it's best to have the highest frame rate possible, especially if you have turbulent air in your viewing conditions. There's little data on the supported exposure settings and quantum efficiency or if the camera is ascom compatible...


Essentially you want to record planets ie make a video clip/movie and imaging deep sky objects like nebula is kind of like using film taking long exposures both these type of imaging can be adjusted with your camera settings on your f510 camera

It would be a good idea to read this article first. It gives a lot of info for you to get a beginning idea of what you'll need for the arena you choose - nightscape or planetary/lunar or deep sky.

Also, high frame rates for planetary imaging take advantage of a phenomenon called "lucky imaging". The above article explains it.

Thanks guys! Much appreciated.

Yes, I have both the Oscar f510 and a Mightex C030-U which I found out has a rolling shutter, which I read is not ideal for AP.

I'll read the article and continue learning, thanks for the help. PS, just realized I've read that article but a few more times won't hurt.

The first piece of the puzzle is on its way here, a Skywatcher NEQ-3 with Synscan. I'm planning to start with either my Nikon D200 or Lumix G7, guessing the Lumix would be the best choice. I have all of my Nikon film gear including a plethora of top line lenses which should work for my initial experiments. I also have the Pentax Takumar 500mm and 1000mm lenses but are non APO but may be fun to play with.

I also will try the Oscar so I can get that working and ready for the t-scope arrival, whatever that may be. I'm currently considering a nice ED80 with a few accessories which are included.

cheers

And that is what I am trying to get a handle on, steep learning curve but for me, that's part of the fun.

Thanks!
