Jupiter HD webcam from Maplins

Recommended Posts

I got a Jupiter HD Webcam today

i have tested it out it works in daylight pretty nice also it actually does have some exposure controll :) thats even with IR Filter still on cam

so it be pretty cool without IR Filter when i mod it to telescope sometime.

it also is YUY2 video setting

and maximum reso is 1280 x 1024

I will test it with moon sometime and for laugh test with Jupiter ;)

Pretty nice cams from maplins

Jupiter HD Cam now modded ready for test :)

jupitercam.jpg

Now modded simple to open just clicks open ;)

took out the original lens so now ready for test with me special lens i usually use first test cams with.

jupiter2.jpg

Now ready for testings along with some other cams on test

skycam2012.jpg

Will possibly mod jupiter cam as EP for me telescope sometime

firstly i test cams normally with original lens but this jupiter cam i have put wider view lens on it for now test see how well it copes with dark skies :)

all cams i have made so they pick up infrared as all cams dont have IR Filter.

That is interesting.

What settings are available using Sharpcap? How about the FPS ?

May you make a screenshot showing all the settings available through Sharpcap?

Who knows it might be a useful planetary cam.

For the highest resoulutions the frame rate is 9 FPS in sharp cap

My screen doesnt show full screen like.

now for normal 640 x 480

yes 30 FPS sharpcap shows.

Here is screen capture.

I think it's pretty nice cam very very easy to mod the lens just screws out easy and holder is just held by simple glue that just peels off easy

i clipped out the orange led no need for that orange bright led.

case just all clips open with flat screw driver. and easy to push case all back and be easy to add bit plastic tubing for your telescope.

and this cam is very very light weight.

will be ideal planetary cam Jupiter :)

not bad for 15 pounds. quick and easy mod.

So it has gamma and exposure settings but no gain......not holding my breath for Planetary with that cam :smiley:

Im going to check all my cams see which ones have the gain control i never thought that one before.

what does gain control do like ?

Generally gain is used to control the Planet brightness with either zero or say 10-20% gamma as too much gamma loses contrast or produces the dreaded onion rings on the Planet disk image. After using the spc900 and before purchasing a dfk imaging source camera I tried a couple of cheap usb 2 webcams purely for the 30fps rate. One of these had only gamma and exposure controls with no gain. Light sensitivity seemed very good when imaging Saturn but the resulting stacked image had horrendous onion rings because of having to use the gamma control to adjust brightness.

Ah rite i have to try that move gain control when viewing planet thanks for that tip.

will have to try that with me cams that have the gain control setting.

I have tested that cam with night sky using me cam testing lens :)

shows some cloud glow so it possibly be great for brighter objects that need less exposure will have to test on moon sometime so i'll probably now make bit tubing for cam test on telescope with moon once it comes in field of view and clouds shifted.

or could just use as day skycam infrared.

as you can see the orange glow from clouds. so i rekon be ideal for moon.

I just noticed using astrocapture in linux does have gain control slider showing up interesting Hmm

i'm bit confused now what software's best sharpcap windows or astrocapture windows and linux.

i'm bit confused now what software's best sharpcap windows or astrocapture windows and linux.

It could be that the linux one is just applying a "virtual" gain to the output image (basically, the same as if you would save

the image as it is and then try to modify gain and exposure afterwards, without the image containing the right "photons data"

to actually improve the image.

On Mac I have tried a software that would give me any kind of control on any type of webcam, however, the results were a disaster,

because basically the webcam sensor is still producing an overexposed washed out image and the capture software will only

be doing some kind of "postprocessing". Said that, I haven't been using Linux for several months now and I never tried that specific software,

it might even turn out that some Linux Kernel modules, or the software itself, do actually have access to those camera settings

the same way that sharpcap would.

You can try out those settings on bright objects during the day. You may make more experiments and play around even with

bright objects at home, like bulbs or maybe do some solar imaging with the solar filter, and make a comparison of the 2 softwares.

Will try that test on few day objects shall mod bit tubing to cam one day for now cam is just as skycam.

Jupiter cam is now modded as EP :)

and it's pretty awesome.

Viewed local chimney must be about 1000 or more meters away. looking good cam. even see see reflections from metal on chimey ;)

Jupiter still looks like a bit overexposed. Is it possible to make it less exposed and get some details / bands ? (Maybe the moons will disappear then :D )

      I'm currently on my annual leave in Italy and the sky has been clear all day with no air turbulence.
      The telescope is out - of course - and I managed a session before dinner.
      I thought about sharing some photos taken with my phone and a couple of sketches.

      Jupiter imaged on 17 August 2019 using a C8 SCT, Skyris 618C at f33.

      Hello All,
      Sharing with you my best images of Jupiter and Saturn for this year.
      I haven't had the luck of a High Pressure system with no wind speed yet, but on the 17th it was as close as I had for planetary this Jupiter/Saturn season.
      Not my best images of the gas giants ever but ok IMO.
      I'm happy to see that the GRS seems to be repairing itself, last time I imaged Jupiter, the border around the GRS looked like it was breaking up so perhaps it'll be around long enough for my kids to see in the eyepiece.
      Captured at f33. Images consist of  the best 15% frames from 13x60sec @ 60fps for Jupiter and 13x120s @ 30fps for Saturn, derotated in WinJupos.
      Clear Skies,
      MG

      Hey all, I just started imaging the planets again after a long break. I have just purchased some new equipment a ZWO ASI224MC and skywatcher ADC (replacement for SPC900). I have read a lot about image quality depending on the height of the planets. The image shows top row images I took in Dec 2012 SPC900 ( looks like the world did not end 🙂 ) and bottom row July 2019 224MC. Would the difference I am seeing in quality be down to just position or am I not setting the new camera correctly? Thanks for any more image examples or help.

    • By PH-R
      Hey all, I cannot believe my luck. I was out on the 31st July practicing imaging Jupiter and Saturn with the my new ADC and ZWO Asi224MC. All of a sudden the ISS started to appear from the South West heading East. I quickly released the clutches on the mount and followed the ISS the best I could with the finder scope. Everything was set in sharp cap for the Jupiter capture, ROI was set to 320 x 240, 2x barlow plus ADC.  I could not believe it out of 6500 frames I manged to find 13 frames, which I stacked. Second bit of luck, PIPP said it could not find an object, so I turned the option off and it ran without errors. The hero was AutoStakkert which sorted the frames to the front of the ser file. 
      Composite of 3 images from my night:
