General Corrections
 'It was only expected to be a 4.2 m, but it turned out 4.3 m (14 ft) could be used.

In this sentence it is unclear what the 'it' is that ended up being one meter larger than anticipated and why that could still be used.

The size of the nucleus to be calculated to be 250 meters (820 feet) in diameter.

Sentence tense is inconsistent with the rest of the section, repeated words make meaning unclear.

Sections
Telescope Section

This section lacks any sort of citations.

This section is in the future perfect tense while many other sections are in the present and past tenses creating inconsistency and making the article feel out of date.

Comparisons Section

This section may be better suited (and less confusing) as a table or chart and should be cited.

Tone
The tone of the article is not entirely neutral. There are many unsupported statements and sections that make the article seem more about opinion than fact.

Additions
A section should be added on the EXPRES (Extreme Precision Spectrometer) added in 2018. Other additions may need to be added as well.

The green 'Christmas Comet' was also observed with the Discovery Channel Telescope in 2018 and should be included.

Other discoveries may also need to be added and the article should be updated to reflect up to date information

The article seems to be very general, without specific information on discoveries, involved individuals, and updates to the technology.

Many advanced concepts are mentioned in the article and linked, but many are not linked (ex. spectroscopy). Linking all the advanced terms to the appropriate articles will help with readers understanding and improve consistency.

Talk Page
One user has used the talk page to communicate adding a link to the page in 2017, but no discussion has taken place since.

Wiki Projects
The article is a part of WikiProject Arizona, United States, and Astronomy. Both projects rate the page as Start-Class (meaning it's developing and missing key criteria) and Low-Importance (not particularly notable and used mostly to cover a specific need of a more notable article).

Conclusion
Overall, the grammar and tense of the article should be carefully looked at to be easier to understand.

More citations should be added to the article. Many of the paragraphs do not feature any citations and could be considered unreliable.
