A few double stars for your observing campaigns.
Some of these double stars have dim elements, down to magnitude 10. So you might need a slightly larger rather than smaller instrument. But I think they are all worth it.
| star | also known as | alternate catalogue(s) |
|---|---|---|
| ψ1 Aqr | STFB 12, 91 | SAO 146598, HIP 114855 |
| HJ 1940 Cep | Gaia 2739178880 | TYC 04302-0707 1, GSC 04302-00707 |

| ο (omicron) Cyg | ο-1, 31 Cyg, HJ 1495 | SAO 49337, HIP 99675 |
A quick note on omicron Cygni. Use every level of magnification you have, starting with Mark I eyeball.
STFB refers to Struve Appendix B.
The Gaia catalogue number is from the second data release (DR2).
Enjoy.
