Subject:	How to use my Canon A1 with the ETX 90?
Sent:	Saturday, December 29, 2007 14:05:10
From:	Sushi (
I own a Meade ETX-90/EC and I am very much interested in taking some
photos with my scope, so I ordered the ETX camera adapter #64 in
addition to the T-mount for EOS Canon (being the only Canon t-mount
available in the online store). I'm only concerned that the mount or
t-adapter will not be compatible with the A1 considering how old it is.

I also own a Sony Cybershot- DSC T20 - 8.1 Megapixels. Would that be an
easier device to use than the Canon A1? If so then what's the best
equiptment to use with it?

Any suggestions on how to use these cameras with the ETX will be highly
Thanks and happy new year, 
Mike here: Get ready to do some reading!  Checkout the various links and articles on the Helpful Information: Astrophotography page on the ETX Site.  There are links to camera adapters, accessories, and articles on Canon and Sony cameras.  Both will be able to do astrophotography of some objects.  Keep in mind that you will need a sturdy mount for the ETX, possibly a counterweight, adapters, etc.

It's just a little question,  I want a new digital camera, but I don't
want a DSLR, because I feel that it is difficult to use it for an
amateur photographer like me.

So, I am choosing among three Canon models, these are Canon G7, Canon G9, 
and finally the Canon S5 IS (8MegaPixels CMOS sensor).  My question
is: is it possible to use these Canons DigiCams for astrophotography?? 
I can not find anything about these models in your Web. I have an
ETX-125PE telescope, if these models are not the best to use them with
it, can you suggest to me a good model, (in the point and shoot type)
because I need a digicam with movie mode, and the DSLR doesn't have it.

Mike here: Any camera can be used for some types of astrophotography. If the camera has a fixed lens you are limited to afocal (focusing through an eyepiece) or piggyback. If the camera has a removable lens then you can also do prime focus and eyepiece projection astrophotography. Any camera you want to use for astrophotography would ideally have a BULB setting (to keep the shutter open), or at least shutter speed settings up to several seconds. Also, it would be good to have a remote shutter release (to avoid enducing vibrations in the telescope when you open the shutter). Lastly, you should be able to control the ISO setting, the higher the better for many objects (other than the Moon). Of course, you will also need the appropriate adapters to attach the camera to the telescope although for bright objects (such as the Moon) that can handle a short exposure you can handhold the camera lens over the eyepiece.

I am trying to find the correct adaptors to hook up my canon g5 digital
to my etx 90 telescope.I am slightly confused.
thank you,Dave
Mike here: How do you plan to use it? Eyepiece projection, afocal, prime focus, or piggyback? Each has certain adapters required. If the camera has a removal lens then you need a T-Ring adapter for your camera model as well as an adapter to attach to the ETX. For more on adapters see the Accessory Reviews: Astrophotography page. For more on doing astrophotography with the ETX, see the Helpful Information: Astrophotography page.

I have some problems with my new canon powershot g3 and my etx 90ec. I
just got the basic camera adapter from meade but I got problems fitting
the cam to the etx.

Which adapters do I need to fit this cam to the etx?

Mike here: The Meade adapter is normally used with a T-Ring adapter on a camera with a removable lens (typically a film or digital SLR). If your camera doesn't have a removable lens then you will be shooting "afocal", meaning that you need to use an eyepiece in the adapter and mount the camera to the adapter. If the camera accepts filter attachments you may be able to find a suitable adapter; if not you can try what I did as discussed on the Accessory Reviews: Astrophotography page.

Here is a shot I took of Neptune with the ETX-125 & a Cannon 350.
It was at mag 7.85 and at a distance of 29.25 Au. 
Amazingly the blue colour is still visible!
