Nice hedgerow today

Despite clear skies, it has been an effort to get anything worth posting lately. Today offered a nice target for imaging.

Re: Granulation shots (TEC140 F/7, X4 & X5 Powermates)

That is so great to see Pedro.
Not only are they great shots, but I just picked up a TEC APO140 myself and now I have an idea of what I might see (I haven't been able to set it up yet). You have me really anxious to use it now.

Re: New camera but which one?

Yes the ASI120 is famous for Newton Rings, but a tilt adapter will do. You probably will need a lot of tilt. (At least I do have with mine, still surprised the complete field of view is still sharp) That took me a while to grasp as well, but think of it in photographic terms. What would the depth o...

Re: New camera but which one?

Yes. If you are still at the point where you're not getting a usable image with what you already have, then you should hold off buying anything new until that is sorted out. I'm sure if we could all stand together in one spot with your gear we could have it solved in a few minutes but alas, we'll ha...

if you click on the frame slider and from there use the arrow keys on the keyboard, this will step frame by frame

Re: New camera but which one?

You might also tell us a little more about what you consider "improved results", as your imaging objectives should help you determine where your money is best spent. You had some imaging problems earlier and I don't know if you have resolved those or not. If not, a better camera isn't going to help ...

Re: Eliminating bad frames during stacking?

Paul - I tried a pass with the Global option and AS tolerated the bad frames, but the alignment problem persisted. Raf's examples with the birds provides another case where trying to describe to a piece of software just what constitutes a bad frame can be very problematic. It's often better to fall ...

Eliminating bad frames during stacking?

What do you recommend to eliminate short segments of bad frames before stacking? Suppose, for example, that a flag managed to flutter in front of your telescope a couple of times during an acquisition. In my case, a person walked in front of my telescope almost in the middle of a 5000 frame acquisit...

Oops! Sorry about that folks. I do my processing in lossless tiff, and failed to convert before posting. I replaced the tif files with jpg. Hopefully you can see them now Thanks to all for the kudos. It was indeed more difficult than I had imagined - and I thought that I had planned carefully. Oxyge...

Mount Evans

The weather was not all that cooperative and wildfires in California added a lot of haze to the skies. But I was in Colorado specifically to put a telescope on the top of Mount Evans (4350 meters/14,265 feet). Forecasts showed that Monday was going be the best and a hotel close to the mountain was s...

Whatever processing you did up to this point has clearly been done with skill and care, with an eye toward detail and a light hand on the adjustments. Well done! In order to demonstrate the differen...

Alex,

I was able to download your tif original. It's a bit late right now and tomorrow looks to be a bit busy, but I'll take a look at it after that.

I just wanted to add a couple of additional comments regarding the paper.

We will need to wait for some more development, but the theory sup...
