luna Posted March 9, 2014 Share Posted March 9, 2014 I am looking to purchase the 'Celestron Neximage 5MP Solar System CCD Astronomy Eyepiece Camera'(i) I would like to know if this can be connected to a Samsung 7" tablet(ii) Is it a good CCD at £199I did want to get a used Canon DLSR camera at £150, but I don't think it would be any good for my Nexstar 130SLT telescope, it may be too heavy.

glappkaeft Posted March 9, 2014 Share Posted March 9, 2014 Which target do you intend to use the camera for? The Celestron camera is intended for planetary and lunar imaging using video while a DSLR is better suited for long exposures of deep sky objects.

bogdog Posted March 9, 2014 Share Posted March 9, 2014 is it this one?http://www.amazon.co.uk/Celestron-Neximage-Solar-System-Imager/dp/B006ZN4VE2/ref=sr_1_1?ie=UTF8&qid=1394372044&sr=8-1&keywords=%27Celestron+Neximage+5MP+Solar+System+Camera%27Celestron NexImage 5 high resolution camera for Moon and Planets - USB Connection - powerful camera for lunar- and planetary imagingCamera Resolution: 5MP - 9 different settings to choose from ranging from 640x480 to 2592x1944Frames per Second: 6.23 to 52.37 at the lowest resolution, 0.71 to 5.99 at the highest resolutionShutter Speeds: 1/10000 to 30 seconds, Chip: 1/2.5" format, color CMOS Sensor, Sensor Size: 5.7mm x 4.28mm (7 mm diagonal)not ccd? maybe better off saving a bit more and buy a dslr,or check secondhand for one Link to comment Share on other sites More sharing options...
Cornelius Varley Posted March 9, 2014 Share Posted March 9, 2014 These days the CCD / CMOS debate doesn't matter that much. CMOS sensors are widely used in DSLRs and astroimaging cameras. Link to comment Share on other sites More sharing options...

The camera you mention is a planetary camera and will be fine on the 130SLT, a DSLR will not. The resolution of the camera is not the critical point of consideration as this camera has extremely small pixels which means the chip size is quite small ( this is fine for planetary imaging if your GoTo system is accurate enough) but very small pixels usually mean a lack of sensitivity and limited dynamic range. From what you have written I would advise you to take your time and do a lot more research before deciding on any purchase. Regards,A.G Link to comment Share on other sites More sharing options...
Kirscovitch Posted March 9, 2014 Share Posted March 9, 2014 I use an Orion StarShoot 5mp imager with my 130SLT and have gotten some pretty good images of the moon, Jupiter and Saturn. I am having trouble with my mount at the moment so haven't been able to use the DSLR on it yet, but just putting the camera on the scope, I think that the mount would hold it just fine. It doesn't seem too heavy at all. (The 5mp imager is pretty hefty in its own right and pretty close to the weight of the DSLR body.) Link to comment Share on other sites More sharing options...

luna Posted March 9, 2014 Author Share Posted March 9, 2014 Phew, good thing I did not purchase the camera. I may try for a used £150 canon dlsr camera. I could stabilise the tripod by using a 5kg sandbag. Link to comment Share on other sites More sharing options...

I could stabilise the tripod by using a 5kg sandbag.You have to make sure that the scope can come into focus with a DSLR, a Canon DSLR has a back focus of 55mm from the flange of the T mount to the sensor this means that the scope must have enough inward travel of the focus tube to be to achieve focus with a DSLR, I am not familiar with SLTs so you need to ask or do a bit of research. BTW a DSLR is fine for shooting the Moon in a single shot mode but I doubt very much if it is going to be of any use for the Planets with a scope of 650mm of FL. As I said take your time and do a bit of research.Regards,A.G Link to comment Share on other sites More sharing options...
riklaunim Posted March 9, 2014 Share Posted March 9, 2014 DSLR + lens / no telescope / on an EQ mount would be good to start DS imaging in such case. Short focal length of the lens would make it easy on the mount tracking accuracy and so on. Link to comment Share on other sites More sharing options...
Astrosurf Posted March 10, 2014 Share Posted March 10, 2014 If the camera has video mode, you can use that for lunar and planetary and stack in Registax. Not done it myself yet though!Good luck!Alexxx Link to comment Share on other sites More sharing options...
