"But it's just Antares you know!!"

Hello everyone!

Well after a little hiatus, I've dragged the scope out to try out my bodgied webcam. Why tonight? Well the moon is nice and big and it gave me a nice bright object to aim my guidescope at, to which the webcam was attached.

Well what do you know, the Logitech webcam managed to not only pick up the Moon but it gave a fairly good picture. However this was not my goal for tonight. My goal was to guide using a star.

So off I went looking for a bright star to try the webcam on. Unfortunately for me, only the brightest of stars were picked up by the webcam. I tried in and about M8 & M22 but there was nothing bright enough to use as a guide star. Undeterred, I moved the scope (via my laptop using Stellarium and the nifty little usb gamepad from Honkers - I love it when a plan comes together!) to a bright star. I pointed the scope at Antares.

After much fiddling I managed to get a bright dot in the PHD window. It was Antares. Very excited I was!! OK, now to try autoguiding my scope using PHD. Attempt one at guiding - not very good. Attempt 2 - not very good. Attempts 3, 4,5 & 6 - not very good...... Attempt 137 - my god, it's working!

OK, so I get my camera and take 5, roughly 2 minute exposures (a total of 8mins, 55 secs) at ISO 800 as well as one dark sub. I race inside, load the shots on to the computer, use DSS to stack, then PS to post-process quickly, Then I type this message, add the photo and low and behold, I present to you, my peers on IIS, my first ever autoguided image!!! (But it's just Antares - I know!)

Cheers,
Mario

PS Now all I have to do is convince the finance department that I need to buy a QHY5.....

Not bad

I've been outside with the binos tonight, and I've very quickly come to appreciate having some nifty gear like a GStar camera. Because my neck isn't as supple as it used to be, thanks to stuffed disks and arthritis. Looking up at Antares nearly kills my neck and back!!!!.

Might invest in one of these...http://www.starchair.com/index.html one day

WOW!, they are 990 years ahead of their time... I remember WAY BACK in 1999 when everyone was thinking... "Hey, next year all of these 2000 thingies all over the world will finally come of age" (at least the sarcastic were saying that while everyone else was going... "END OF THE WORLD!" Y2K BUG WILL KILL US ALL! )

Well done Mario - its a nice feeling when it finally works isn't it?!

It would be nice to get the QHY5, to be able to guide off something less bright than Antares!

You know, we're expecting multi-hour guiding sessions from this setup, now

Great going Mario - guiding and the shot of Antares!
You can actually do quite a lot with a ToUcam on your guidescope/guider - as long as you have a decent field of view to find brighter guidestars. A QHY5 is far more sensitive and convenient, but there tons of things you can reach now.

Rob,

I'm working with a Logitech webcam not a Toucam - Antares was the only thing I could get in that part of the sky (directly overhead) besides the Moon!! Still working in conjunction with the finance department at home regards the QHY5!

Cheers,
Mario

Oops - should have read more carefully.
Agreed a QHY5 is one of the best investments you could make right now. Perhaps a WANTED posting on the IIS classifieds.....

Newsflash!

The finance department at home has approved the QHY5. I won't go into the details of the negotiations but suffice to say the words "Birthday" and "Father's Day" were bandied around!!!
