Mert, I think part of the problem is that the extrafocal image shows a strong heat plume in the upper right area. You can try to reduce the impact of this by ...
John, Thank you soo much for taking the trouble looking into these images!! And yes, you are absolutely right, the scope was just taken outside and I had some...
Mert, OK, the large temperature change probably explains many things. The large spherical aberration may also result from the temperature change. There can...
John, I would say thanks to you, I'm getting a better feeling on Roddier testing thanks to your help and insights! I will try and go out some other night and...
Hello to all, Finally I got it right this night, quit steady air, seeing something like 4/5 and transparency 3/5. Ordinary webcam 5,6 um pixel size, 1800 mm FL...
Mert, I had a quick look at it. Seems good this time -- no heat plumes; images have good signal and low noise. I get about same result for your images --...
Thanks John, Only thing left now are my eyes :-((( since I have soo much troubles focussing! When I start imaging I hope to obain nice focussed and sharp ...
Hello, I tried roddier with your two vega-xxxx-090407.fit files without any success. After loading, I get the intra display in the upper left corner of the...
Hello Alain, Please go to the sub-directory ( folder ) 090507 Vega and here you will find the images: Vega-intra090507-crop145.fit Vega-extra090507-crop145.fit...
Thanks Mert, It worked ok and I got the same result as yours. Looks like SW is doing some very nice optics these days. Lucky man :-) Roddier seems to be very...

Alain, Good to hear that it worked! I finally got good results with Roddier SW when I started to save the cropped images as 8bit unsigned integer, maybe that...
It really is more like a beta version with a few bumps in the user interface for sure. But the calculation "guts" of it work well with a good coorespondence...
Hello Philip, I completely agree with you! This program is rather unique and very valuable, which make it even sadder to leave it forever in this beta state. ...

Hello Alain and Philip, Maybe it would be possible to keep on developing this software, but the author should authorize that. Apart from that I would like to...
Hello all, Does anyone here have experience with the Voyager USB2 camera or the DMK 21AF04 firewire camera ? My requirement is to be able to have a simple...
Hello Dan, Please check: http://tech.groups.yahoo.com/group/DMKCCD-cameras/ I would very much like to have a camera like this but that's going to be in the...
Hi Mert, Our application is to revisit the optical quality for our telescopes at Palomar. The 200 inch sometimes has surface errors that become noticeable...
Hi Dan, I remember measuring PSF sizes on the P200 couple decades ago for some similar effort. Glad to see folks are still interested. - John B. ... method...
Hi Dan, Thanks a lot for the time you took to write up such an interesting explication for an amateur like me! It has always been a dream when I was a child to...
On one of the other astro groups the statement was made that Roddier analysis requires 16-bit FITS files to run, and that it will not see any other resolution....
Hi Mick, ... Roddier will only read 16 bit FITS files. However, it is relatively easy to convert whatever format you have to 16 bit FITS. Many imaging...
