    I've seen this group many times in my 12.5". I don't really have anything in my notes that would add to the above.
    I first saw it in 1994 with an 8".
    Given the magnitudes and the transiting...

    From my notes with 12.5":
    Small, roundish oval, diffuse edges, bright core, stellar nucleus, moderately bright overall, near bright star ß And

    I consider this one of the easiest DSOs to find. My...

    In my notes with the 12.5", I note the core has a "stellar nucleus"
    I made no notes of arms, but did find the galaxy bore magnification well.
    I used >300x in the 12.5".
  4. This one culminates for me at 21° above the...

    This one culminates for me at 21° above the horizon, but even at that altitude it is hard to resolve completely into stars in a 32cm scope.
    I can see why--the horizontal branch is mag.17.7, and the...

    It looks like the outer arms have been distorted on both sides.

    Reminiscent of NGC247, but more disturbed than 247:...

    I have this recorded as "seen, but incredibly small. Not much in the way of details at 300x, and slightly oval."
    One of the tiny PK planetaries.
  7. I will have to look at this again. My last...

    I will have to look at this again. My last observation was with an 8" in 2001:
    med.size, faint, round, somewhat diffuse, slightly flatter 1 side, only few *'s vis, no strong core, slightly brighter...

    It is a quite impressive galaxy even with a smaller aperture.
    My notes from an 203mm scope in 1995:
    "large, roundish-oval, face-on spiral, outer areas diffuse like M51, very impressive!!!, bright...
  9. This one has a huge spread between its overall...

    This one has a huge spread between its overall integrated magnitude of 9.5 and the magnitude of its horizontal branch (17.8)
    In 32cm, in near perfect seeing, the outer edges become grainy (as from...

    About Boötes:
    Many comments about the constellation being void of objects are related to small apertures.
    In my 12.5", I have logged (so far) 282 objects in the constellation. It is a rich...

    Well-placed for May observations, as it culminates at 11:33pm as of May 8th. It's just south of M83, so be certain to look at M83 when you're in the area.
    Fascinating history. Great write-up....

    Recent estimates of the Milky Way's size extend the disc of the galaxy to about 150kly because of the identification of an outer arm not previously known, ignoring the halo, which may extend to...

    This galaxy is the brightest member of the galaxy group AGC 2029
    I found it decent, but not spectacular in the 12.5" at 203x as it culminates at an altitude of 60° at my latitude of 35°N.
    It is...

    I've always seen these (12.5", 21.4-21.5 skies) as two cooked shrimp.
    I never see the full length of the tails, but I always see some tail on each.
    The small, round, B&W image here is very close to...

    From my notes, using a 12.5":
    (M3)large, irregularly round, loose concentration for a globular, somewhat flattened on one side, bright, fully resolved, core is 75% of total, quite populous!

    It is...

    Astronomy equipment emits moiston particles, around which water condenses into opaque droplets called clouds.
    Only the light of the Full Moon is capable of burning through these moiston particles...

    And what about the visibility of the barred spiral nearby--UGC8877?
    It seems it should have been visible in the 48".

    One note: at 40°N, this object culminates at an altitude of 19°. That's low, but not "dirt diving" low.
    That's 6° HIGHER than the Bug Nebula in Scorpius, and a degree higher than Messier 70 in...

    US importers buy from the factories, they do not buy from foreign retailers. A foreign retailer could very well still have stock when the US importer is sold out.

    Put it this way:
    If your skies are dark enough, your 16" may be able to detect (not necessarily see well), well over 50,000 galaxies.
    You won't live long enough to detect them all. And in many,...

    I would guess that transparency has a lot to do with it.
    There is no guarantee that a dark sky is transparent at any altitude, but higher is usually better for lower extinction.
    In my experience,...

    I detected it in a 12.5" in 2020, sky magnitude 21.45 (SQM), 166x with TeleVue Apollo 11 (altitude of site 8350'), seeing excellent:
