Re: Info about 130GTX + 0.72x QuadTCC + ASI6200


Hi David

Thanks for your advise.

Would you have some pictures to show me? This would be great.
Of, maybe, you could send me a single image (fit), via a Wtransfert or dropbox.

Thank you for your help

They’ll be fine. I have the same setup except it’s a 130GT. Corners are good with my QHY600.

I use an ASI6200 camera for my deep sky photography. I have the opportunity to buy a 130GTX with the QuadTCC reducer.

I am looking for information and examples of images made with this material. I would like to see how the stars are in the corners of the image. Indeed, with the ASI6200, there is no tolerance.

For info, actually I us use a TOA130NFB and the TOA-35 reducer. The image circle is 44mm.
If in h-alpha, the elongation of the stars in the corners is acceptable, in luminance the deformation is too important.

That's why I'm looking to the 130GTX.

Thanks in advance for your help.
