Well done! Thanks much for sharing your work. Clear Skies

Nicely done, Rusted. I really like the last b/w one. It really reveals dramatic details. Thanks for the shares. Clear Skies

Excellent work, Chris.😀 I'm partial to the first one. Thanks for sharing your work. Clear Skies

Great work, Nigella. Thanks much for sharing your images. Clear Skies

Sure! Here it is... I also sent you a PM with both attached.

A couple of days ago, I posted an image that covered almost the entire NE quadrant of the sun. The image contained a couple of decent proms close to each other and another little "bump" that I decided to leave without cropping it out. I've been experimenting with a fairly new application recently called Gigapixel AI by Topaz Labs, and decided to see what it could do. I took my original shot (TIFF) that was 800x643 pixels and doubled its size to 1600x1286 pixels. I then cropped out what I wanted to keep to a "new" image that was 673x859. Gigapixel did a good job at "stretching" everything. However, there were a few "speckles" that sort of resembled noise, so I stuck it back in Photoshop for a very little fine tuning... Thanks for the peek. Clear Skies John

I set up early yesterday to shoot that tiny sunspot that had developed. However, by the time the sun was high enough to shoot it was gone. So I shot this anyway. Thanks for the peek. Stay Safe & Clear Skies John

Seeing was terrible at 0900hrs and promising to get worse. So I waited until the sun was above 30 degrees and took the shot. Thanks for the peek.😀 Clear Skies & Stay Safe

Nicely done!😀 Thanks for sharing your work. Clear Skies

Lots of action there... Certainly worth the wait.😀 Thanks much for the share(s). Clear Skies

Seeing was 4/5 due to high smoke from the California wildfires west of my home in Las Vegas, Nv. Outside air temp was 108 deg (F) with just a hint of wind. Thanks for looking.😀 Clear Skies

Good work, David.😀 Thanks for the shares. Clear Skies

One of the US forums (TheSkySearchers) is having a processing "challenge" starting tomorrow (Sep 15, 2020) and they're going to use some of my data. I found the two AVIs of a full disk/proms from the Fall of 2016. It was shot with a Lunt 60PT and an ASI120MM cam. The data is available in my public DrobBox if anyone wants to tinker around with some really old (four years) stuff. The proms are at: PROM DROPBOX LINK The surface is at: SURFACE DROPBOX LINK No password is needed as it's a Public Folder.😀 Since it is my shot, I figured that I'd better process it some. NOTE THAT I ACCIDENTALLY PUT THE YEAR AS 2018 ON TWO OF THE SHOTS BELOW. IT WAS REALLY 2016.😀

I'm a big fan of Alexandra's work, and this award-winning shot is an example of why. Congratulations Alexandra!!!!😀

Great job, Steve! Thanks for sharing with those of us who are out of luck right now. Clear Skies

I've never tried the 178, but bought a 174 when I started using a Quark. It performs very well with the Q. Clear Skies

Nice work as usual, old friend.😀 It's been a while for me, but I still enjoy your images. Thanks much for the share(s). Clear Skies

I've been away for a while, but when cleaning out my auxiliary drive I stumbled across this AVI that had never been processed. So, just for fun, I processed it. From October 2016... Thanks for the peek.😀

Excellent work, GA. Thanks for the contributions. Clear Skies

Michael, I want to thank you for this thread. I've overlooked it previously, but decided to read it carefully yesterday. I had never been successful with ImPPG previously, usually ending up with "junk" when trying to set the compound curves and the sharpening settings. Your simple explanation and the screenshots finally pounded it through my thick skull. I "played" with it all day yesterday. Thanks Again! Clear Skies

Paul, regards your new ASI120MM-S, we have a saying in the US... "That dog will hunt."

I'll second everyone's recommendation of the ASI120MM. Make sure to get the "-S" model, as it's USB 3.0 and can deliver faster data. Monochrome is the only way to go in my opinion for solar work. A mono cam uses all of the pixels, whereas the color cam of the same size only uses the red channel... only one-fourth of the pixels. Clear Skies

I can't really testify regarding that model. Try Googling " DMK21AU618". There are some reviews of that cam there.

I have two ASI174MM cams that are both cooled. There is a tilter on one and not the other... just because I'm lazy. LOL I also have an ASI120MM-s cam that is not cooled. The "-s" means it is a USB 3.0 model and the "MM" on all of them indicates that they are monochrome. Cam cooling is often not necessary. However, I live in the desert southwestern US where average daily summer temps average 117 degrees Fahrenheit. It those temps, a cam's chip can become overheated resulting in dropped frames and a signal-to-noise ratio that is uncomfortable to deal with in post-processing... to say the least. I was out for a one-hour session today where the outside air temp was only 68 degrees (F) and the SharpCap cooling control never even turned the cooler on. I use SharpCap for my imaging software. SharpCap will monitor the chip temps for you during imaging. I just refer you again to my earlier thread in which I recommend a USB 3.0 cam. If the cam offered locally is not a 3.0 version (with the "-s), I would avoid it. It's not that you can't use it, but the 3.0 protocol is where we as an imaging community are currently at because of the advances in personal computers.

I only recommended a fast processor because they're not that much more expensive than the slower ones. As long as you're pumping USB 3.0 data out of the cam, you'll be fine. However, a slower processor may drop some frames at the higher capture rates. Don't let that be a show-stopper for you. Best,
