What is it that causes someone to undertake astronomy as a hobby? I certainly believe that one of the primary drivers is
the majesty of the night sky - especially when unencumbered by light pollution.
It is a visceral awe that arises from your soul when you behold a sky that is
ablaze with stars.

Another incentive is the invitation to ponder the fantastic. We learn of things such as suns collapsed down to neutrons where a pea-sized portion of it would be measured in tons, and we contemplate storms on other planets lasting centuries.
Yet a third enticement is the thought that one might contribute to that body of knowledge. In bygone decades the discovery of a comet was the goal of many a dedicated amateur observer. Others have fastidiously and relentless made magnitude estimates of variable stars, or timed the central meridian crossing of Jovian features. But then the automatons arrived, tireless robotic scopes and orbiting observatories capable of being the eyes on the universe in a way amateurs cannot match.
The perceived loss of relevance is certainly real. Witness the genuine excitement of our community at the prospect of providing exo-planet transit timings to help scientist improve their knowledge about these distant worlds. I fully expect companies like Celestron to soon begin marketing tools to help those who wish to participate in this work.
Planetary observing has been an astronomical passion since my first “real” telescope that enabled me to see features. I started by sketching Jupiter, Saturn, Mars, and Venus to submit to the Association of Lunar and Planetary Observers (ALPO). More recently I’ve taken up imaging as it yields results that are far superior to my aging eyes and artistic talent.
After so many years of just being an ALPO member, I decided last year to volunteer as the coordinator who posts images and sketches from observers across the globe to the ALPO gallery. Twice this week, in email exchanges with individuals who contribute their work to the gallery, I encountered the sense of inadequacy. “It is impossible to keep up with the big guns,” was the lament from one. It can be deflating when comparing one's work to the astounding images produced by amateurs equipped with larger scopes, deeper pockets, and a firm dedication to their craft. Indeed, why bother to capture an image when you know there are others whose work is consistently an order of magnitude better than what you can achieve?
First, I’d argue that self-improvement is never a wasted effort! As you become more familiar with the equipment and software your end result will look better and better. This, in turn, is likely to encourage you to buy that next piece of equipment or program that can push your current boundaries of expertise. You may never reproduce the results of someone like Damien Peach, but that is true with any hobby – from needlepoint to swimming there are dedicated “amateurs” who will always be the ones we strive to emulate.

Secondly, you’ll never know when it will in fact be you who witnesses a rare event. It happened to Ethan Chappel two years ago as he was carrying out “lucky imaging” of Jupiter when he recorded a momentary bright flash that turned out to be a boulder-sized meteor striking the planet. He was the only person to capture the event which helps scientists to calculate the frequency of such impacts at Jupiter. If it happened to Ethan (and others over the last decade), it could certainly be you the next time.
A final motivation is that your observation is likely unique. The top gun amateurs are not out there 24x7 capturing video of the major planets. Your photo or sketch can be very useful in determining the drift in longitude of a Jovian cloud feature, pinpointing when and where that Martian dust storm originated, or refining a brightness estimate of an inbound comet. Advancing science is often achieved through many data points – be one of them!
Yes, the professionals and leading amateurs have the equipment and resources to provide us with stunning planetary images. But that should not be any reason to rule out the citizen scientist role you can play by persistently going out and reporting on what you see to organizations like ALPO. Keep refining your skills and keep looking up – who knows what opportunity for discovery you might encounter?
