You may wish to consider either a new or secondhand 120mm f/5 achromat instead. With the right eyepiece these are excellent wide-field deep-sky scopes, and are preferred by some observers to the 150mm f/5 versions.
This was highlighted during a recent episode of The Actual Astronomy Podcast, namely episode #483 -- Affordable Wide-Field Astronomy with Brian Ventrudo
