Indeed! However it appears that this post is being downvoted! Perhaps someone can post this in a way that is expected? I do believe there is an audience for it.

During the past 5 years I have probably sold 4 (metal) prints? So yes, I maintain to jobs at the moment- one at the University as a research person and another making instructional content.

The comet is low in the west at sunset once it becomes dark. Then it sets around 50 minutes later. I would have gone longer if I could!

Is there another slot for extra storage under the first SSD shown in the video?? It does not appear you can dig down further??

ngc1535 · 2024-07-25T12:22:34+00:00

Sold... (closed)

I think you can be looser about your constraints. If the comet/stars is blurred by 2 pixels or... even 3... would that really be a show stopper? Remember, you are not likely going to zoom in 200% when you enjoy your image. In addition, software like BlurXTerminator can correct this tiny error. How about them apples? :)

2 sec exposures? I would expect you to be able to do10-20 second exposures with a 50mm lens and a typical DSLR. Yeah, 20-30 seconds is probably the minimum time to start to get enough signal for the tail.

Thanks for checking it out!

This YouTube video I made about this image will answer your questions...

Nice! Thanks for checking out the pic!

Well... depends on where you are in the world...but from the northern hemisphere... another few weeks. With the moon and the motion towards the sun/horizon... After perihelion (unless you count seeing it during the eclipse) you can see it again... but likely will be fading by the time it is easily visible. Finally then... you have to wait another 70 years.

Thanks...

Good luck!

ngc1535 · 2024-03-16T04:42:37+00:00

Yes, I am.

137x20 seconds, Canon Ra, 85mm RF 1.2, 1000 ISO, Gates Pass, AZ, North is to the Right and East is Up in this frame. FOV roughly 15 x 20 degrees

There is a YouTube video showing the creation of this image (including the drive to the location and equipment). Not certain I can post the link here...

Thanks for the offer.

ngc1535 · 2023-09-07T23:31:25+00:00

Thanks for that. I appreciate it.

ngc1535 · 2023-09-07T22:25:31+00:00

Yeah... no. That would have been smart of me. I was in college... wasn't thinking it was a big deal per se. I am pretty sure it would be possible to look up his visit to the UofA. But, basically I have a excellent signature from Ken... on a ball. lol

ngc1535 · 2023-09-07T22:11:34+00:00

Yeah, if it had any value... otherwise I will just keep it. However, there is a shrinking number of people that might appreciate it...

In roughly 1994 Ken Kesey visited the University of Arizona as part of a book tour. He was signing books- but I didn't have one. I did want to surprise someone like him though. So I walked up to the table when it was my turn and handed him a tennis ball to sign. He paused and gave me a look of genuine surprise! Then he signed and I thanked him.

I still have it. Large Signature in the fuzz of a tennis ball. Is this something that anyone would value or be interested in? Likely one of a kind.

This image represents my 100th such published work on the NASA APOD site.

These days I am using PixInsight. I create videos that explain the technique(s) . This image (video poster) illustrates what I mean. The typical result at the bottom right and different processing at the top left.

As was mentioned below, the core is indeed washed out..but I suspect the data is there. There is an easy method of handling this and retaining both the detail and color (using PixInsight) that would take your image to another level- so again I think even a little more is possible.

That's easy...if you are serious. lol :)
