The Hunt for "Fuzzies"

(also see my 2003 Messier Marathon Report)


I had to wait to year before being able to repeat Messier Marathon again (spring of 2001 was completely clouded over here in Eastern Ontario).

This year it did not look too promising either. Together with Doug Angle and Fred Barret, we were planing overnight observing. Our first choice was Saturday, March 16 (two days after New Moon). And while it was cloudy (or terribly windy or both) for almost a month, that Saturday morning turned out sunny and calm. The weather stayed perfect whole day and around sunset both me and Doug made it to Fred's place near Maberly, Ontario. Still, there was no sign of clouds or fog...

After a short deliberation we picked up observing spot on a hill above large beaver pond. Southern and Eastern horizons were perfectly low. There were trees (no leaves on them here in Ontario, yet) to the West. So early in the season, we thought they would no interfere with objects above Western horizon. Well, as you will see, it was not exactly so...

While it was slowly getting darker, we set up our scopes. Fred was using his 8 inch f10 SCT, Dough brought 4 inch f4 refractor and I lugged my trusty 6 inch f4 Dobby. It was getting chilly as well but it was still perfectly clear.

As Venus sunk below horizon, it was dark enough to located starfield of the first target - (in)famous M74. Young Moon (with beautiful Earthshine) guided me there but I was for a real surprize when I have reached hPiscis at 7:05 pm - comet Ikeya-Zhang was plainly visible in 8x50 binoculars next to that star! I kind of knew that visitor was hanging somewhere around Western horizon but never paid too much attention as it was cloudy all the time anyway... It looked like a good omen, for sure! 6 inch Dobsonian showed not only a head but a tail over 1 long. Once sky got a bit darker, that tail seemed to go almost all the way across 2 field of view.

Comet Ikeya-Zhang.

Eventually it got dark enough to try the hunt for M74 in Pisces. After a bit of confusion, I was able to find right area near hPiscis but it took me many minutes of staring (with averted vision) to detect its faint round glow in my telescope at 48x (at 24x the sky background was too bright) at 7:47 pm. A few minutes later, while still relatively high in the sky, it started to disappear behind above mentioned trees. With that accomplished, I was on to the good start of this Marathon.

The nigh proved to be clear until sunrise, when clouds finally rolled-in from the south. It was really damp and bitterly cold and we had to fight with iced crystals growing on optics and elsewhere (see "Lessons Learned" part at the bottom of this page).

After 9 pm. we got company... Wolves started to howl on the other side of a large beaver pond (at least we felt that way) but Molly (Fred's Collie) was not brave enough to pick it up (probably she agreed with our estimate of their location).

It was truly a memorable night of observing.

Lessons learned

"Running" Messier Marathon with others allowed me to compare advantages and problems of using different scopes. Between Fred, Doug and myself we used:

Instrument

Comments

  • 8 inch f10 SCT on a fork equatorial mount
  1. DEW!!! To fight it you need power which is a problem at remote sites (and those are the only places best suited for Marathon)
  2. Fork mount makes finding objects along horizon quite akward
  3. Because of the small field of view, original finder was of little help for fainter objects.
  • 8 inch f5 Dobsonian with an open truss tube
  1. We hardly used that one but dew again was a problem. Primary mirror eventually managed to frost over completely! Using a shroud would prevent that.
  • 6 inch f4 solid tube Dobsonian
  1. 6 inch proved to be a minimum aperture to clearly see fainter of the Messiers on that particular night (M74 was really difficult, though !)
  2. Solid tube protected optics from frosty dew - only secondary sported some ice crystals on optical surface by early morning.
  3. Eyepieces fogged over rapidly, though. I had to keep changing them every few minutes - while one was in the scope, the second eyepiece was warming up inside my pocket (having two identical eyepieces would be nice :-) Replacing metal focuser with plastic one (yes, that's what I mean) would definitively slow down heat (cold ?) transfer.
  4. Because of the large field of view of this rich field telescope, red dot finder was completely adequate. Each time the target was in the field of view at low power (about 2 at 24x).
  5. Alt-az mount made it easy to hunt objects along horizon.
  • 4 inch f4 refractor on alt-azimuth mount
  1. Thick objective lens started to dew over, eventually (it was a really humid and cold night).
  2. 4 inches were a bit short on aperture for some objects.
  3. Finding targets was easy by sighting along the tube (no finder). At lowest magnification the field of view was about 4 !
  • 10 x 50 binoculars
  1. When the name of the game is to find so many objects in a relatively short time, nothing beats binoculars. Many of the clusters as well as quite a few galaxies and nebulae were visible in that instrument.

March 16 seems to be a bit early to catch morning targets - M55, M72 and M73 escaped due to rapidly brightening sky. On the other hand there was plenty of room to spare with evening objects - even M74 was still high after dusk. March 25 may be the better date as morning objects should rise about 40 min. earlier while M74 and M77 should still be visible if Western horizon is low! I will wait for new Moon around that day in years to come (and pray for weather to cooperate ;-)
