Einige Astro-Aufnahmen mit TS / GSO 6" RC Teleskop + ZWO ASI294MCPro Kamera


Dear Karl,

Please see attached the screen captures which I took on my first session on 15 June 2018. These are as they appeared on the screen, without any processing, with no darks or flats applied. As you can see, all are at 15 seconds exposure and 320 gain.

There is a green tint in the images which is perfectly normal, because the colour matrix of the ASI 294MCPro is RGGB (Red, Green, Green, Blue). This is of course easily corrected post processing, or in SharpCap, by reducing the green channel.I found that the camera is extremely sensitive and perhaps the best option for Electronically Assisted Astronomy currently!

I really enjoyed mounting the TS 6" RC on the AVX mount. I operated at a focal ratio of f6.76 or 1,027 focal length, by spacing the reducer at 60mm from the sensor. The scope arrived PERFECTLY collimated and you have my thanks for that! On the AVX mount, only a single counterweight is required to balance the scope and I think that the 6" RC and Celestron AVX is one of the best combinations as the mount is perfectly comfortable with this weight for imaging. 

In the future, I will first take darks to eliminate noise and then flats with the flat panel you sent me. Although there is insignificant vignetting at nearly f7, flats will also eliminate any dust on the sensor from the images. SharpCap, the software I use for Electronically Assisted Astronomy, can use a master dark and master flat (it averages the darks and the flats to produce a master dark and master flat) and adjust each frame taken for noise, vignetting and dust adjustments!

I am very grateful for your help in choosing the appropriate telescope for what I wanted to do and for refusing to sell me scopes which you KNEW were not appropriate for what I wanted to do.

Clear skies,
