Current ARs from June 16 afternoon

Post by gabrieli »

These were taken using an Aries 265mm ERF + C9.25 + 3X Baader Telecentric + Quark Combo +FLIR (5Mp) Blackfly during mid afternoon (1 - 2 pm local)
Yes, the scale is a bit much and the images a bit noisy (due to stacking only 200/1000 frames) but I haven't found a suitable reducer yet to bring it down to about 4500 - 5000mm without adding too much overhang. The Quark was showing very good contrast but the seeing caused very jittery fine detail.

The camera feels more and more comfortable now and I found that by reducing the ROI to 3Mp (as for the images below), the frame rate could be nudged up to about 98 fr/s if the image brightness allows it.

Very impressive!! :bow

I don't understand why it would be so noisy though after stacking 200 frames, I only ever stack 50 and they seem OK?

Hope you don't mind, but I've cleaned up some of the noise.....

Not ideal as I worked from your JPG file, but it shows promise.

As Stu implied, the noise came from excessive processing (over use of wavelets). The scale displayed should have been reduced a bit,
