My first astro scope was a Kmart 4.5 inch f/900mm reflector with 20mm and 6mm Huygens eyepieces. It took a while, but i eventually discovered that the secondary mirror was bent, due to pressure in its holder. X shaped stars. Bought a new secondary from Astro Optical Supplies and fixed it. My first good eyepiece was a 9mm Carton volcano top ortho.
