I purchased a used Logitech Webcam C160. Turns out that the chip is from the Quickcam SP4. 640x480 1/8" sensor.

Would anyone here know which CMOS/CCD is it based on?

Hi Sathya. I have the Logitech C100 CMOS sensor (not QuickCam chip) webcam and am getting some good results from it when atmospheric conditions are very good. I had a quick search for specs and reviews for this webcam and sensor but didn't find much, not sure if it's CMOS or CCD yet. 640x480 video res max 30 fps, 1.3mp single shots (software enhanced interpolated).

You should be able to get better results than what I'm getting as I'm relatively new to AP. My better results where stacked frames from avi videos through my SkyWatcher Pro Series Mac150 with small extension tube, not Barlowed, manual tracking using AMCap software.

I have managed to run my C100 at 640 x480 with higher frame rate up to nearly 60 fps with another piece of software but data transfer is high on USB2 and it's dropping frames on my little low spec netbook. I'm still working on this issue between other tests.

Thanks Dave! I usually do planetary imaging with my DSLR at 640x480 and 50fps. The Logitech webcam is one of my latest experiments in using a bog standard webcam for autoguiding. I have not taken keen interest in planetary imaging, though I do dabble in Lunar imaging once in a while. I mostly like to do DSO's for their size and vivid colours.

According to this listing on amazon it is a cmos http://www.amazon.com/Logitech-Webcam-Sensor-Manual-Microphone/dp/B00XHAU6AY . Whether it is cmos or ccd these days doesn't matter.  The resolution is 640x480 sio I would expect the sensor size to be 1/4" not 1/8".

I measured the sensor and its about 3-4mm diagonal. If it is indeed 1/4" type cmos then I guess low light sensitivity would be good for guiding.

I've thought about webcam guiding myself, downloaded a couple of free guiding programs but don't know how to set it up or what to do from there.

Let us know if you have guiding success Sathya.

Dave, I've had guiding success using a dedicated Guidecam and PHD guiding software. Do let me know what setup do you have and I would be more than glad to help you out with getting started. :)

      This is a close up of IC 2944, also known as the Running Chicken Nebula or the λ Centauri Nebula, with the Bok Globules visible in the upper third of the frame. IC2944 is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star λ Centauri. This image was exposed using a Cooled and full spectrum astro modded DSLR through a 8" SCT at it's native 2032mm (f10) focal length. The total exposure time was 8 hours and 25 minutes, through a UV/IR filter to capture natural colour data.

      The view of the deep southern part of the Milkyway around the Southern Cross, Crux, and Centaurus region. This image was taken with a Canon 5D mk4 using a Canon L-series 24-105mm Lens set to f4. Image taken from a mountain, a dark(ish) location, down southern part of NSW near Kiama, called Saddleback Mountain.

      NGC 6357 is a nebula about 5500 light years away in the constellation Scorpius near the better known NGC 6334, AKA the "Cat's Paw" or "Bear Paw" nebula. This nebula was also given the name War and Peace Nebula because of its appearance in infrared images, the bright western part resembles a dove and the eastern part looks like a skull. This photo was taken through a 8" SCT at f6.3 (1280mm focal length) and exposed using a full spectrum modded and cooled Canon 40D DSLR.

      After a few months of getting used to my new 8 inch beast, I decided to start astrophotography (luckily today is Black Friday in most tech shops in my country). So I decided to drop the idea of buying a DSLR and started thinking about getting a webcam. The thing is that I want to try deepsky AP, so i was wondering, is there a webcam that could get me good results for DSO AP? Don't worry, I don't want anything too fancy because I'll be happy with entry-level images. (i saw some nice Andromeda pictures with 20GBP cameras on this forum so I'm confident that it would work).
      My budget is ±100 GBP, which in my opinion is more than enough for a good webcam . So... is it worth getting a webcam? Or is there something better? Should I wait and raise more money for a DSLR?
       
      Thanks a lot!
      Astrid
