  1. Dob's epic first night under dark skies

    Successful night out Neil, great that you were sharing in this with a bunch of like minded people.
  2. Half the Mob with half a Dob...

    Nice report and descriptive range of targets, good outcome after such an abysmal and challenging winter, particularly liked the punch line on the closing comments.
  3. Skye ,with 10" Dob

    Fabulous report Nick, you transported us all there. Losing your way through the constellations, that's what its about.
  4. 10" dob

    It may depend on your current appetite for aperture gain. As Doug indicates often the thinking is 8" to 10 or 12" and this was my own conundrum at a time that I became curious for the extra % light grasp. I would have settled for either, for similar reasons talked about. Perhaps if your attic (overlooked that thanks Stu for highlighting) has a steep stairwell, perhaps a 250mm would be safer to carry, lots of considerations. My aperture 'fever' has diminished since currently using a 350mm dob, I feel that it is enough, although I remain curious and interested to experience the views with larger aperture, such as opportunities if possible at star parties. My interest in aperture has actually gone into reverse and I equally enjoy an 200mm dob and small wide field refractors. The reasoning is that my personal appetite is for dark sky and a desire to take dark sky readings / go stargazing at increasingly remote locations.
  5. 10" dob

    Hi Gert, I went from using an 8" scope to a 12" flex-tube and it was appreciably superior. The 8" sct I had been using became redundant and consequently sold. Visually it made a huge impact and either 10" or 12" is a gain. Concerning the manageability of the 300p flex-tube (manual version), it is a bit heavy, but adequately handled by one reasonably fit person and collapsed is quite ergonomic. Mine was kept upstairs and was OK to carry out to the car or set in the backyard.
  6. The H-Beta Filter

    As previously mentioned Neil, perhaps as a future consideration, an additional eyepiece with a larger exit pupil will be advantageous. Your intended 20mm will undoubtedly receive a lot of use, including with this filter, a close to optimum exit pupil for (perhaps one night) gaining a glimpse of the Horse Head. It should be suitable to try on a range of targets with the H-beta, an eyepiece such as a 30mm will have benefits with (and without) a H-beta filter, not something to hurry into, particularly where finances are concerned.
  7. The H-Beta Filter

    The California is certainly an object that as an interest may grow on you, through gaining in familiarity, yet will initially not reveal much. My first encounter, which was assisted by an experienced observer, was to determine the 'brighter edge' more so a faint grey passage and to cruise along its length. This was a few years ago and I have increasingly become more accustomed to observing this object. Now I can determine the nebula structure much more substantially and I can detect subtle details. I share with others that have commented, it has become a favourite object to seasonally observe and discover yet further subtleties in its features. As mentioned, the right conditions and placement of the object is necessary for a revealing observation.
  8. Shedding a few layers is good, here, the down jacket is replaced with a down vest, late summer nights can become chilly.
  9. What's your favourite bit?

    The favourite part of astronomy is highlighted each time that I am able to become transported to a dark sky destination and privileged to encounter a clear sky. The occurrence is infrequent, yet the effort required to get there melts away, replaced with an animated feeling of living in the present moment, with much anticipated exploring / discovery ahead. I feel that I have evolved as a visual astronomer and enjoy planning new possibilities to gain access to yet darker sky locations, that will determine the potential of my equipment.
  10. Yep I'm looking forward to that aspect to, short sleeved cycling jersey, etc. Having other interests and hobbies ensures that you are kept occupied.
  11. You have to get what you can, when you can, how you can. Been on a family visit to Fylde coast Lancashire. Astronomy was not on the agenda as the forecast looked not so great as usual. As an after thought I took along my binoculars, monopod. Glad I did as last night became lovely and clear, so enjoyed touring the clusters around Auriga, Gemini, Cancer, concluding with the Beehive Cluster, a perfect binocular object. The ISS cruised overhead before my Dad came out to remind me that the Sky at Night was due to start. So quite satisfying after a lengthy period of no activity. Patience, going with the flow with the familiar forecast disappointment, keep on planning and aspiring and retain options in terms of approach.
  12. Observing Report from Baltimore environs, SW Cork

    Thanks for clarifying. Such a reference is perhaps useful as a very generalised (in my experience to date fairly exaggerated) guide only. Readings from such light pollution maps are over stated, except for perhaps exceptional rare conditions in the early hours of the morning. As you say a Unihedron Sky Quality Meter is a useful gadget, if your aim is to seek dark sky locations to go observing, night lapse photography, imaging. Then it is better to take your own readings, on the night and time that you are there to form an accurate account of overall sky brightness, magnitude. Also to learn and understand how to use this devise and under what circumstances and to work on the average reading. FLO stock the Unihedron, the SQM (L) accounts for readings within the vicinity of zenith and is the commonly used model.
  13. Observing Report from Baltimore environs, SW Cork

    Nice report, could you expand on the quoted SQM reading, did you use a reference from the current on-line Light Pollution Map, or did you take your own meter readings? If you took your own readings, with a Sky Quality Meter such as Unihedron, was there an average? The best regarded readings are usually on a moonless night and in the early morning hours and when transparency is excellent.
  14. Relay Session

    Neil here is a glimpse into Insterllarium, I believe that you have a copy incoming. The filter references make for good guidance, in addition it is worth while experimenting with other deep sky filter types, drawing your own conclusions and taking note of observers reports, particularly such as those of Gerry's. Mark's suggestion for placing on a separate music stand is practical and applied by some observers. I keep mine in the car when out on a dark sky trip, excuse to get a bit warm and sip coffee whilst studying charts.
  15. The H-Beta Filter

    Just one other thought, you may in time wish to consider including a low power eyepiece with a larger exit pupil, such as Explore Scientific 30mm.
