AR2749 with C11 + ARIES D-ERF - NEW, 7 frame stacked image added

Post by yltansg » Fri Oct 04, 2019 3:36 am

We are now in the inter-monsoon period. Bad - It is raining every day. Good - Rain cleared the haze from plantation fires in Indonesia.

There was a half-hour window this morning. I am very glad to have obtained some video.

Setup
Image

This is a close-up view of AR2749. I used ImPPG for the deconvolution and minimum processing in PS (contrast and USM sharpening). Do a right-click to see the image at full resolution. It was formed by stacking 1000 out of 2000 recorded frames.
Image

It was taken at 9:49 am local time. 15 minutes after this was taken, rain clouds rolled in and the whole sky turned black. RH probably around 90%. I was pleasantly surprised to get this reasonably good image.

Cheers.

Alfred

Thanks Alexandra and Maurits.

It rained from 8 am to 9:15am local time. It took me about 30 minutes to setup the C11 on the mount and start recording. This is the first time I did recording after a rain. I thought the high RH (about 90%) is bad but it turned out quite ok for imaging. I managed to record 6 videos, going through the rest now. They look good too.

Thanks Jack and Franco.

I also some video of it in extremely poor seeing the day before on 3 Oct. This is how it looked at 11 am local time:
Image

This AR has not grown much from 3 to 4 Oct. Weather forecast predict rain again today, but we never know how it turn out. Hope to catch it today again.

Thanks Stu and Mark.

All 6 videos turned out good. The rain did wonders to clear away the haze!! The following are also from 4 Oct session:

Image
This is a cropped version, of the 9:49 am image that I first posted. It zoomed in on the AR.

This next image was taken at 9:46 am local time with 1000 out of 2000 frame stacking

Image

As part of my experimentation, I decided to stack just 7 out of 2000 frames from the 9:46am recording
Image

I am always impressed by Christian's stacked image using small number of frames and decided to give it a try. I must say I am astonished that I am able to get such a good image by simply stacking 7 frames. What do you think?
