We enjoyed some moments of steady seeing in Brisbane last night, (23rd Sept 2018) and whilst cruising the almost Full Moon with my Tak Mewlon 210 F11.5, I thought I’d have a crack at seeing how far I could push the image scale using the following combinations:
- Tak x1.6 Extender. (efl 3864mm at F18.4).
- TeleVue x2.0 PowerMate. (efl 4830mm at F23).
- TeleVue x4.0 Powermate. (efl 9660mm at F46).
The camera used was a ZWO ASI 174 MM, with FireCapture and set to record 4,000 Frames for each AVI.
Workfow.
- AutoStakkert!3 to select the best 33% and Align, Stack and save as TIFs.
- Open each TIF Registax and apply the same Wavelets Settings.
- Open each TIF in PS CC and crop to 1024x1024 at full resolution from the 1920x1200 image.
- Process each file and save as JPG.
I was very pleased with the performance and image quality using the Tak x1.6 Extender and TeleVue x2.0 PowerMate and I honestly did not expect to obtain anything more than mush with the TeleVue x4.0 PowerMate, but was pleasantly surprised with the results, albeit soft and fuzzy.
I have included a Plato image at with the x4.0 PowerMate which has managed to reveal several of the smaller craterlets on the dark floor.
Cheers
