Hello roddier test community! Now I found the error for my halb size of star images on the CCD chip for the NexImage camera. The problem depens not on...
Hi Peter, et al., My NexImage arrived. I agree it has no Barlow or any lens, just a window protecting the CCD. I made some test images and compared the...
Hello John and all other of roddier test community! I checked the star image size problem for format 352 x 288 (cetral part of chip without binning) also for...
Hello John and all other of roddier test community! I made an error comparison of K3CCD and AMCAP. For all test and all formats I got allmost the same error. ...
Hello Roddier Test Community! It is very calm here in the roddier test group in the last week. I want to give a small new impulse. As you remember I looked for...
Hi Peter, Yes it is quiet in the group and alas, I've not been able to hoist my equipment out so from me no news neither. Some mecanical problem in my body :-(...
I have uploaded an intra and extra focal image from my 18" f/12.6 classical cassegrain to the files section folder marked the same when I try to use these...
i uploaded two cropped versions of the same intra and extra focal images i have co-registered them in maxim and did a blink test in maxim to ensure they really...
Richard, I think the background is too high relative to the star image. Try subtracting some constant from the images to bring the background closer to zero....
i took them right at sundown on a hot day so it had to be thermal at least in part. thanks for the suggestions, it makes sense to me to have to reduce the...
Was this a single CCD frame or short exposure? Maybe stacking more frames or longer intergration would help average-out some of the brightness variations due...
Ok thanks for the suggestions it was a single exposure of each i think the best thing to do is to take a 30 second guided exposure on a star that is less...
Hello group! I've tried tonight to image Vega, 1000 images intra and 1000 images extra focal, through Registax V4 and cropped with PixInsight Light and finally...

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. ...
