I've been waiting for a few weeks to give this combination a go and I managed to grab 4 shots tonight before the clouds moved in again.
4X2 min ISO400 Canon300d unmodded, ED80 and Meade 6.3 Focal Reducer, autoguided with ToUcam and K3CCDTools. Dark subbed and combined in Imagesplus, post processing and cropping in PS.
To be honest I was expecting more. There is pretty serious vignetting and the FR certainly doesn't flatten the field as much as I'd hoped, stars near the outer edge were almost triangular. They weren't too bad in near the center but I wouldn't call them round.
The first shot has only had levels (and quality and size) adjusted to show the vignetting, the second shot is the first but has had a median filtered duplicate subtracted and quick curves and levels and the third was cropped before adjusting.
You think your focal reducer is bad? I've had two from Bintel (original was replaced) as the vignetting and field curvature is beyond ridiculous.
Don from Bintel did say to me that the current batch (at the time) weren't much good as they were being made by a new manufacturer. I think I will try and return my second one, as well.
I tried Louie's Celestron F/6.3 and it did a much, much, better job, without as much vignetting and curvature.
Once again, top shot and I'm glad to see some new images from you.
Thanks for posting the results. I must try my Celestron F6.3 R/C on the WO 80mm and see what results I get. Hope I have the necessary adapters! Nice photo by the way!
Thanks for the support guys. I'm trying to make the most of every chance I get atm with the way the weather is and these little things irk
Theses are the stars that I was talking about. Funny thing is the "coma" is the opposite direction to normal. This crop is from about halfway out from 104 towards the top left hand corner. You will also notice a bright star in the lower left of the original that is quite out of shape. I think the FR is overcorrecting the normal curvature of the ED lens.
I think that is NGC121 Spearo. Its in the right orientation for when the image was taken and matches up with postiton of some of the stars.
What I would like to know is if anyone can identify the circled object in the second image here.
Bintel have an adapter called an Orion Camera Adapter Prime Focus 2" for $59. You screw it apart and the silver 2" barrel screws into the female C thread of the FR and the other piece (which has female C and male T threads) screws onto the male C thread. Works like a treat. When using it you have about 8mm of in focus left.
