Yes, the Hadith prohibiting using calculations for moonsighting is in Sahih al-Bukhari .
ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا، عَنِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، أَنَّهُ قَالَ: «إِنَّا أُمَّةٌ أُمِّيَّةٌ، لاَ نَكْتُبُ وَلاَ نَحْسُبُ، الشَّهْرُ هَكَذَا وَهَكَذَا» يَعْنِي مَرَّةً تِسْعَةً وَعِشْرِينَ، وَمَرَّةً ثَلاَثِينَ
Ibn ‘Umar narrated that the Prophet ﷺ said, ‘We are an unlettered Ummah, we do not write or use (astronomical) calculations. A month is like this, and this.’ Meaning sometimes 29 and sometimes 30 days. (Bukhari , 1913).
This Hadith has been narrated in Bukhari, all Hadith that have complete chains of narration in Bukhari or Muslim are Sahih.
وأجمعت الأمة على صحة هذين الكتابين، ووجوب العمل بأحاديثهما (تهذيب الأسماء واللغات)
The Ummah has unanimously agreed the fact that these two books (Bukhari and Muslim) are Sahih, and that their Hadith narrations must be acted upon. (Imam al-Nawawi, Tadheeb al-Ismaa wa al-Lughaat).
And Allah (Most High) Knows best.
