Wanted to try this with the QHY8L that I bought recently but the vignetting was terrible, presumably due to the massive chip size not being illuminated properly by the small exit on the Skymax 127 ? So slapped on the Meade DSI IIIc instead

Haha, nice one

Love the images I recently bought the QHY8L & used it on Mon night with my SW Ed80pro, 12x5 min subs, no darks flats or bias & ended up with this, though had to crop because the rest looked all wishy washy

Wow , thats top banana

For a 1st try thats brilliant, I've tried a few times & this is my best so far :/

Fantastic images

Looks great

Hi, hope you don't mind, just had a play with your image in photoshop and came up with this

Hi Phil It may be something to do with Quicktime It happened to me with no images showing, I think you need the latest version of Q/T It was a while ago but i'm sure I found the solution by googling S/N6 & Quicktime Hope you get it sorted Greenkat

Hi Gareth Have you gone through the procedure of training the drives? Cant remember how its done as I gave up on the ETX's I had (70 & 90) a long time ago. You could try Mike Weasners website Mike and Laurraine's Home Page which is dedicated to all things ETX After giving up with the ETX I got a Skywatcher mount & took the tubes off the ETX's. Dont do that if you've borrowed it though Greenkat

Also regarding focus : Most camera lenses focus beyond infinity. The thing to do is turn the focus ring all the way to infinity, then back just a notch. Take a test pic to check focus. Hope this helps Greenkat

Hi Lou Not sure if this is the answer you are looking for but here goes... If your husband is only casualy interested in astronomy, it may be unwise to spend your money on a telescope he may only use a few times. With the equiptment he already has, he can already do quite a bit of astrophotography by just mounting his camera on a tripod and taking longer exposures of the night sky. My advise would be to maybe buy him a book on astrophotography and see if he enjoys the hobby. If he does, you could possibly buy him a motor driven equatorial mount at a later stage to mount his camera on to do even longer exposures. Then a telescope to use visualy and take photos through. It would be a shame if you bought a telescope for his birthday to find it later stands there gathering dust. Hope this helps you a litte Greenkat

Hi John I could be wrong, but I dont think it would matter if you flipped the image before processing and might actualy help you process the image better if your seeing it in its correct orientation. Im sure someone will correct me if I am wrong Greenkat

Hi Don Cant help you with that particular filter, but I have a minus violet filter from a company called Sirius Optics. Works ok on my 6" F5 refractor. Greenkat

I dont use the same equiptment, I use a skywatcher mount, a DSI3 camera, guide camera & joystick. I have a 4 port powered USB hub conected to the laptop via a long usb extention lead. Both cameras, Usb-serial mount adapter and joystick all conected to the hub. Hope that helps Greenkat
