What about the space-based telescopes, Hubble, etc
Hubble arguably has given the best optical pictures yet. 169.207.87.68 12:51, 8 Dec 2003 (UTC)

Orphaned references in Timeline of telescopes, observatories, and observing technology
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Timeline of telescopes, observatories, and observing technology's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "Topdemir": From Timeline of telescope technology: (cf. ) From Alhazen:  From Taqi al-Din Muhammad ibn Ma'ruf: (cf. ) 

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 01:07, 13 March 2010 (UTC)

Unreliable source - Muslimheritage.com material
Content from Muslimheritage.com / FSTC is an unreliable source, as discussed on Reliable_sources/Noticeboard/Archive_18. None of its publications are peer-reviewed, and its authors often exhibit a strong bias and incomplete or flawed citation practices. The site has been used as a source in numerous science and history of science articles to make extraordinary claims about Islamic invention and discovery. I am working to remove these extraordinary claims where they stem directly and solely from a Muslimheritage.com reference. Many of these claims were added by a user who has a history of using flawed sources for extraordinary claims, as discussed on Requests_for_comment/Jagged_85. That page details numerous examples where claims from these sources contradict more reliable sources, on a scale which casts the entirety of the material originating from the site into doubt. If you would like to discuss this or any related removal with me, please leave a note on my talk page. Dialectric (talk) 18:37, 29 April 2010 (UTC)

Hellenistic times
the timeline completely misses the Hellenistic astronomers like Eudoxus, Hipparchus, Eratosthenes, Aristarchus and Ptolemaeus, so attributes to Biruni the inventin of planisphere, when before him Marinus of Tyre and Ptolemaeus had already invented some map projection.
