Quote:Is it possible to get some good advice as to "how to best observe" certain classes of objects? Perhaps something more than just the standard advice of taking a well collimated dob to a dark site during a new moon. The idea is the get some advice on how to best use the equipment one has, rather than recommend some specific eyepeice, etc.
Quote:How best it observe galaxies? Its been said that 150 to 225 power is best; others say 2- 3mm exit pupil. What is your rule of thumb on this?
Quote:Any techniques on getting the views for nebulas?
Quote:Globs? Any special techniques?
Quote:Finally open clusters.
First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.

Quote:Great advice above. I'd add the use of a hood to block extraneous light.
Quote:1. How best it observe galaxies? Its been said that 150 to 225 power is best; others say 2- 3mm exit pupil. What is your rule of thumb on this? Any other advice as to how to maximize the quality of the view (other than getting a better eyepiece.)
Quote: 2. Any techniques on getting the views for nebulas? Emission, reflection, dark, and planetary - these are all very different objects. Do you do anything different for each class of these objects?
Quote: 3. Globs? Any special techniques?
4. Finally open clusters. Maybe these would not all be considered deep sky objects, but any techniques?

Quote:Try DSO filters for emission and planetary nebulae. If a dark nebula is in front of an emission nebula, DSO filters can help (for instance, an OIII for the Horsehead - B33).

Quote:Another tip: Avoid all white light at the dark site! This will degrade your deep dark adaptation for an hour or more after each exposure. In fact, avoid any light except for dim red light. If you use red light for your tablet, notebook, or flashlight, dim them as much as you can and still retain ability to see. Use Velcro to attach red filters over any lights inside your vehicle.If you are serious about observing DSO at a dark site, don't view bright planets except for when you first arrive and immediately before you leave. A look at Jupiter will degrade your dark adaption. But here's something that many observers don't seem to understand: It's also important not to mix observation of the faintest galaxies and other dim objects with any brighter objects, not just planets. After locating and viewing faint galaxies for a couple hours, I've noticed serious damage to my level of dark adaptation after a quick look at a bright globular or even a moderately bright star.Mike
Quote:Almost all red flashlights that you see at star parties are FAR too bright -- mine only allows me to see a small circle on the chart from a few inches away. Any brighter red light is only for working around the scope or double star and planetary observing, not for serious deep-sky observing.
Quote:Avoid all white light at the dark site! This will degrade your deep dark adaptation for an hour or more after each exposure. In fact, avoid any light except for dim red light.
Quote:All of the above sounds great. I would also recommend extended/prolonged viewing of each object.Don't jump around quickly. A long hard look at an object will bring out details.

Quote:Quote: If you use red light for your tablet, notebook, or flashlight, dim them as much as you can and still retain ability to see. Perhaps it's just me, but I find I lose considerable dark adaptation for awhile after using even the lowest setting of my red flashlight. After checking a chart, I find I need at least 5 minutes to really recover.
Quote:1. Five or ten minutes on a galaxy is hardly conclusive. If there's one paramount but of advice Ive gleaned from CN its PATIENCE . Let the mental "stacking" of your deepsky eye/brain have time to really saturate itself with the subject.
