These are my very first attempts.  I used an old Meade Barlow to get some image scale. I’ve got a ways to go but happy with this start.

 

Question, I’m using an old laptop for these, any recommendations for a newer one with enough power and  memory to take multiple imaging runs without shutting down the laptop?

 

TAK 130, ZWO 462, 2x Barlow.

That's a very good start.

Most people on this forum will tell you don't need to have the very latest laptop to do imaging with. If you are able to record images at speeds of say 100 to 150 frames per second then you are doing well. Of course you need to have the storage on your laptop - solid state storage is preferred to disk drives because of the writing speed. The other thing to ensure high frame rates, is the region around your target (ROI - region of interest). Try and make this as small as your mount tracking will allow. This helps keep frame rates up and allow you to collect more frames for stacking.

I'm sure you have a ton of other questions.

Cheers Paul

So my laptop says my C drive has like 651GB available and 5.88GB of memory.  It was able to record a two-minute run of Saturn which saved to my C drive,  but when I switched to do same run at Jupiter the laptop crashed.  I think I was out of memory??

Did you reduce the Region Of Interest (ROI) before capturing? It doesn't look like you did. That will radically increase the memory requirements, IO throughput requirements, file size, and processing time, and possibly significantly decrease frame rate.

 

Nice first images, by the way. All they need is to be brightened up.

Lack of java heap for FireCapture will not cause the laptop to crash. This sounds more like a USB driver issue.

I like the way you brought out the details in your 2nd processing of Jupiter. good work
