Eclipse through clouds

Gregg Ruppel
 

Hi all:

A moderate layer of clouds blocked my view of the lunar eclipse, but I was able to grab a few images through the obstruction.  These two frames were about 5 minutes before totality:

Hi Dan,

I get what you did and I think I'll copy that. Much apprec.

And I'll be using that ASCOM driver as well.

Re: Flats panel

Dan Crowson
 

Rick,

 

I haven’t looked at mine in ages but I think it is just something like a standard picture frame. I ended up mounting mine on a wall using the scrap wood. I put a board below and above it and then another on top of these to make a ‘lip’ to keep it in place.

 

If you haven’t already seen it, past observatory partner Andy Galasso wrote an ASCOM Alnitak emulation driver for these so you can use the same commands.

Hey you guys with the Spika-A Flat, I am having one shipped to the obs to replace an Alnitak Flat Man Large that is mounted on a TV wall arm and I wanted to know how this thing is mounted to a surface. I can mount a piece of plywood the same size as the panel to the TV wall arm but what is used to attach the panle to the plywood? Are there clips, machine screws? What is on the back of the panel I guess it what I am asking. Thanks much. Rick Darden.

Simply spectacular, Bernard.  The saturated colors bring out all the details.  Does the extra elevation of this target from Rio Hurtado improve SNR w.r.t. DSNM?

Re: FW: Next ASEM Digital SIG meeting - Ron Brecher - PixInsight Deconvolution and Sharpening - Tuesday

The recording on Ron’s presentation can be found here - https://youtu.be/gWOXAQATQRU.

 

Excellent NB image you posted on CN.

 

For anyone reading this, I’m always looking for imaging topics for our meetings. They are the 3rd Tuesday monthly. Our group is fairly advanced (more so than I am with PixInsight). If you have anything you’d like to present or suggestions on topics or presenters, let me know.

 

While Missouri is pretty much back to business as usual, our monthly in person meeting location is on a Department of Energy site and I’m thinking it is going to be some time before we can move beyond zoom.

Concepts in Image Processing: Deconvolution and Sharpening; Noise Reduction and Smoothing

 

ASEM Digital SIG - May 18, 2021

Ron Brecher

 

OUTLINE

 

Deconvolution and sharpening are two tools that can be used to enhance detail in deep-sky images. Although they seem to do the same thing, they achieve different goals, are done at different times in the work flow, and require different masking considerations.  Similarly, noise reduction and smoothing may appear similar, but they have different goals and are used differently, and at different places in the workflow.

In this presentation, Ron will demonstrate these image enhancement techniques using PixInsight, including where they fit into his image processing workflow, and how to dial in the most important settings.
