To extend on my last post, my waning interest was brought on by my lack of observing, lack of opportunities to observe.
Astronomy is very much a passion of mine. Just was looking at exploring other hobbies to help with my lack of observing as of late.
You can't have too many hobbies. Even ones that get put on the back burner for years, like astronomy for me, can resurface later in life.
My grandpa lived to 99 and he had good physical and mental health until nearly 98 but he didn't have any hobbies and after his wife died he seemed pretty miserable for his last 20 years because he didn't have anything to do. No hobbies. And at that age he didn't seem to have any interest in picking up new hobbies.
Before I saw that you had purchased a 115mm refractor, I was going to recommend a grab and go refractor to compliment your larger instruments, especially since it sounded like you were more burned out with work than astronomy.
I have a 20" dob (about as large as I can handle by myself at my age) kept at a dark site, but driving out there takes time, set up and collimation takes time and energy, and then there are cooling issues.
My 4" Tak doublet is much easier to set up and cools down in just a few minutes all year round.
Like you I still have work obligations and the weather frequently gives me partly cloudy nights (or cloudy nights with maybe a break for an hour or two of clear sky) and the 4" refractor lets me get some observing in on nights where work obligations or weather conditions would preclude observing with a larger scope.
I've been amazed what I can see with just 4" refractor under light polluted skies. Planets, double stars, carbon stars, open clusters, globular clusters, a few of the brighter planetary nebula and of course the Moon are my targets of choice for evenings at home. Last week after the moon set I was able to find M71 and to my surprise my little Tak was able to resolve it even with the light pollution of an urban back yard. Just last night I got a good view of Jupiter. Although I couldn't make out Europa in transit, many bands, two barges and the GRS were visible. Epsilon Lyra was easily split at 100x (never gets old). The Nova v1405 in Cassiopeia looks like its brightened to about mag 6 again, and I spent about an hour trying to learn some of the main features on the Moon. Perhaps not as exciting as tracking down an Abell Nebula in a big dob under dark skies but an enjoyable two hour observing session in the back yard with a small scope, with very little set up time.
And it's not like your 115mm refractor is going to lose value. So if you ever decide to sell it you can get your money back. I see no downside to the purchase.
Some of the older folk around here are going to recommend something smaller for grab and go, but at 36 you won't have any problem with setting up a 115mm quickly and with very little effort. I had about ten times as much strength and energy at 36 as I do now at 54. The advancing years and some health issues have slowed me down a bit. One reason I got back into astronomy two years ago, I suppose -- the amount of energy required for astronomy is much less than the hobbies I was pursuing at 36. "Once I moved about like the wind." Not anymore, but I can't complain. At least I'm still moving.
