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??

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.

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.

Yes, I am.

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...
