== Biografi ==<br />
Han var førende i sin innsats for å oppdage [[komet]]er ved hjelp av ulike typer kikkerter, herunder noen han konstruerte selv. Han skal ha bidratt til å identifisere tolv [[komet]]er. Gjennom 50 år brukte Machholz mer enn 9000 timer på kometjakt.<ref>{{Cite web|url=http://auburnjournal.com/detail/145919.html|title=Patience leads to new comet discovery by Colfax amateur astronomer|author=Gus Thomson|date=30. mars 2010|accessdate=30. mars 2010|publisher=Auburn Journal}}</ref><ref>{{Cite web|url=http://www.skyandtelescope.com/resources/proamcollab/astroalert/89322402.html|title=New Comet Machholz|publisher=[[Sky & Telescope]]|author=Roger W.

Machholz var en av initiativtagerne til [[Messier Marathon]], en konkurranse som går ut på å påvise samtlige objekter i [[Messierkatalogen]] i løpet av én natt.<br />

Machholz døde den 9. august 2022 på sin ranch i Mohave County i Arizona i en alder av 69 år,<ref>{{Kilde www|url=https://ground.news/article/earthsky-don-machholz-1952-2022|tittel=EarthSky {{!}} Don Machholz, 1952-2022|besøksdato=2022-08-12|dato=2022-08-09|språk=en|verk=Ground News}}</ref> avkomplikasjoner forårsaket av [[covid-19]].<ref>{{cite news|url = https://universemagazine.com/en/famous-amateur-astronomer-donald-machholz-died/|title = Famous amateur astronomer Donald Machholz died|work = The Universe Space Tech|date = 8. august 2022|accessdate = 27. august 2022}}</ref><ref>{{cite news|url = https://earthsky.org/human-world/don-machholz-1952-2022/|title = Don Machholz, 1952–2022|work = EarthSky.org|date = 9. august 2022|accessdate = 11. august 2022}}</ref><ref name=astro>{{cite web<br />
