I visited a few from your report last night with my XT8. NGC40 & Sigma Cas while in those areas. I really enjoyed them both.
NGC 40 - Bow Tie Nebula is a nice planetary nebula even with a moderate size telescope. I had what I would call variable transparency last night which made this observation difficult but the seeing was good so I was able to push the magnification all the way to 436x with a Meade 5.5mm & 2x barlow. There was was a nice elongated corona that ran N-S around a bright core. The central star was intermittent as the transparency shifted from average to below average. There must have been a thin layer of vapor moving through. There was a 12th mag star - GSC 4302-0545 right near it just to the SW. Even at 218x the oblong shape was obvious and I could see It was flanked by 2 - 9th mag orange stars that added interest. This is a good object for the suburbs and should be even better on a night with good transparency.
NGC 7023 - Iris Nebula & Collinder 427 - This is what brought me to Cepheus in the first place but it proved to be a difficult observation. NGC 7023 is a reflection nebula with a bright 9th mag star in the center. The problem is the star is so bright it makes the nebula difficult to see. It completely washed out the 13th mag open cluster Collinder 427 which is right next to it. I did manage to see some nebulosity extending around the star but I couldn't see the cluster at all. This probably needs dark skies and maybe a larger telescope. Certainly better conditions than I had.
Collinder 463 - This is a large open cluster in Cassiopeia that's one of my binocular targets. It was easy to pick up at 50x with the ES 68º 24mm and just fit in the field. It was an interesting mix of relatively faint stars with a nebulous haze from unresolved stars throughout. I'm actually surprised it shows in binoculars but I guess the collective mix of stars is just bright enough to detect. This is where I realized the transparency was constantly changing as the fainter stars slowly dropped out of the cluster and then over time reappeared. Looking up there were no clouds visible.
Iota Cassiopeiae - This is a beautiful triple. Even though the seeing was good the transparency made this a tough split as the scatter from 4.6 mag A component made it difficult to see the space between the 6.9 mag B. Sep is 2.9" but it took 217x to get them cleanly split. The AC sep is 71" and the C is mag 9.1. Once split ι Cas was a bright white with the blue/white B right up against it and the fainter rich yellow C much further from the 2.
NGC 7789 - Caroline's Rose - This was positioned well and I think the transparency improved a little. I viewed it at 50x, 75x & 136x. At 136x it filled the eyepiece and the small stars resolved well. The swirling patterns from the chains of stars and the dark voids between them are so intricate it takes time to study it and take it all in. The low power view - 50x was interesting in another way. The fainter unresolved stars created a haze of light with specks of resolved stars and dark areas in between. It may actually be easier to see the rose shape when viewed like this.
Sigma Cassiopeiae - Thanks to JD I stopped by this while in the area. I forgot what a nice double it is. The A-B sep is 3.1" at 326º but they appeared closer to me. I had a nice split at 218x. The mag 5 - A component looked white and the mag 7.2 - B a very deep blue to me. Very nice!
M52, CZ43 - After that I made the hop to M52. At 50x I had a nice view of M52 together with nearby open cluster CZ43 both separated by a line of 4 colorful stars. The bright orange 4 Cas was in view to the N. Shifting toward 4 Cas I picked up Hrr 12 the Y or wishbone asterism. Hrr 12 has a deep red 6.71 mag super giant at the base of the stem and 2 nice 6 mag orange/red stars on the S end of the Y. Together with 4 Cas there were a lot of colorful stars in view. Back to M52, I viewed it at 136x & 215x. At 215x it just about filled the eyepiece with stars set off by a bright yellow star on it's SW side.
M31, M32, M110 - I got to this a little late and the moon was just starting to rise. Still at 31x I could see the dust lane in M31 just above the core to the NW as a sharp drop off. M32 was below to the S as a hazy spot. M110 was visible to the NW as a faint diffuse glow. I tried following the dust lane in M31 at 50x but it didn't seem to extend that far from the core in either direction. M32 was easier to see at the higher magnification and M110 showed a little better as well.
M33 - Moving closer to the Moon I thought this would be a long shot but I did manage to locate and spot it at both 31x & 50x. It was very difficult to see against the brightening sky but showed as a large diffuse area with no defined core or edges. I consider just detecting this at home a win for me.
I made a trip in with my observing chair, table and eyepieces and on the way back noticed M45 was above the tress. With no eyepieces I took a quick look at it through the 9x50 finder. It's close to what I get with binoculars and was the perfect ending to the night.
How in the world do you remember all this. Amazing. Some really great targets too.
I haven't been scanning mush this year, due to too few and such short windows. Not being in that mode, I fail to note (or remember) other objects seen. i.e. the triple you mentioned near NGC40 or how various nebulosity around quite a number of targets. I really do need a secretary. Maybe a push to talk recorder.
