    Hi Akarsh, you are having the common problem...

    Hi Akarsh,

    you are having the common problem of seeing Merope's Nebula for the first time. For me, this was a challenge as well, as there may be problems with moisture in the air, dew, and the...

    I had to dig this out!

    This had been on my list since it had been posted here, but I never made it to observe it (I had made wrong finder charts for it :-( ). Two day ago, I finally made it.

    This is definitely a nice spiral. I looked at it last week with my 22":

    There is an oval bright core surrounded by a large oval halo (axes of the ovals not in line). In this halo structure the...

    Hi Howard,

    this is a nice edge on, appeared three days ago with my 22" as a slender spindle, brighter and thicker in the middle. I observed it with 270 and 500x, but could not make out the dust...

    Great target, Christian!

    I had it on my list already last week, but then forgot about it.

    So I looked at it two nights before (my fifth observing night in this not yet ended new moon period...
  6. Hi Jimi, I observed this superthin galaxy...

    Hi Jimi,

    I observed this superthin galaxy three nights before with my 22". At 270x and 500x, it appeared as a very slender silvery streak next to this uneven pair of stars. The star superimposed...

    Hi Steve,

    I took a look at this group with my 22.

    At 500x, the main body appeared faint, small and elongated (but with no clear resolution of the small "companion"). The tidal arm or whatever...
  8. So ... I had another look at it the night before...

    So ... I had another look at it the night before and now I spend more time to pin down H, which proved not to be too difficult. I could hold it almost steadily with AV with my 22" at 500x.
  9. I observed this galaxy again after several years...

    I observed this galaxy again after several years two nights before with my 22". Aptly named a starburst galaxy with quite a number of brighter knots and too many details to be pinned down. Funny...

    Hi Uwe,

    I had three nights in row with (almost :-) ) only galaxies. When scanning the Leo Cluster, I also visited Copelands group with my 22". As usual, it took some time to get a rought picture...

    For NGC 5972 with z = 0.03, the OIII 501 main line should be redshifted by about 15nm. That's also the center wavelength used in the study (see here http://www.stsci.edu/hst/phase2-public/12525.pro)....
  12. Hi Howard, I have observed the cone three or...

    Hi Howard,

    I have observed the cone three or four times with 20" and 22" reflectors, always under (for my location at 1200 m) exceptional conditions (6m5+), using my Lumicon H-beta filter. During...

    Hi Paul,

    this is a really nice pick as OotW!

    I have observed the propeller several times, though not in the past years. My observations were with my 14 and 22" Dobs. The field can be easily...

    Hi Ivan,

    I sit most of the time at my 22". It's a lowrider and f/4, so eyepiece height is quite low at around 160 cm at zenith. The seat I am using is this one

    Hi Uwe,

    great Object of the week. I haven't observed this pair for some time, so my notes are from a few years ago:

    With my 22" Dob, the tidal streamer to the North is not particularly...

    Hi Marko,

    great that you picked this up! Your conditions must have been quite good as you could see the filamentary structure extending from the bright NW rim (I see that clearly only during good...

    I looked at the Intergalactic Wanderer last night with my 22", as I could not remember its precise appearance from previous observations.

    Last night, the globular appeared absolutely smooth, no...

    I have observed the double quasar a few times with my 22", but I was never as successful as Alvin. I never succeeded in cleanly splitting them. Any attempts remained always ambiguous. 6" separation...
  22. Hi Johannes, I have never tried to observe...

    Hi Johannes,

    I have never tried to observe both EGB 1 and HDW1 the same night, so I have no direct comparison. But from my memory, I would say that EGB 1 should be brighter and easier than HDW1.
  23. I had observed this PN a few weeks after Uwe had...

    I had observed this PN a few weeks after Uwe had posted his observation in a German astronomy forum.

    With my 22" at 300x the PN was very faint, but well visible with UHC filter. The disk was...

    Hi Steve,

    thanks for bringing this one up. A very interesting object that I haven't looked at for two or three years.

    I haven't tried any filters either. The RN was quite obvious during my...
