  1. Outdoors, I have another cover, an old airport complementary, large polythene, ski bag for draping over inside, used as a dust cover. When used outside it becomes purposeful if left for a few hours for nightfall incase of any passing showers, as well as when at a dark sky site for if some weather blows in. The draw cord is also useful, it does not flap about or behave like a wind sock, should it be at all a little breezy. Just for the record and to complete the set, here is a picture for the indoor, dust proof, storage arrangement complete with Braathens Air 'flight bags'.
  2. Cygnus Astro Covers, underwent consultation for having one made for my 8" dob, a few years ago. Fits OK, used on a few occasions, was good value so yes worthy of consideration. Picture of the dob and with the cover on.
  3. Hi Robert, see if you can get Mirach's Ghost in Pegasus. Might also be a consideration if you have a pair of binoculars to take along in case dew became late on a potential issue.
  4. To extend from John, perhaps a Planisphere, a dim red led light and (free software planetarium) Stellarium onto your phone and PC. Maybe a stool or chair, a mat for the dob to rest on, a compact garden or camping table. As mentioned, Turn Left at Orion, is the number one guide to get you going.
  5. Yes I was wondering whether that might be the target you were unsure of as it is separate from other areas, was trying to find that star you mentioned on Stellarium. Applying a H-beta filter into the light path, may as you say diminish the image, could open up the exit pupil a bit more, think next time I will employ a 41 Pan for a substantial 7.73mm ep, but the UHC did strike a balance and was satisfying enough. The Propeller is supposed to respond to a H-beta filter, once again perhaps a large exit pupil would help here.
  6. Great, that refreshes my own memory roaming through Gamma Cygni. You got some good conditions Neil, with a lovely assortment of targets. My own evening had been of two halves with transparency better earlier on and later moisture becoming too problematic. Good that you were able to verify an improvement in defination and brightness using a Lumicon UHC in comparison to an OIII in that region. Yes exit pupil on selective subjects counts for a lot, a 5.09mm exit pupil; 31 Pan as ever worked well for myself. I think next time I get to observe in this region, I will use a H-beta on the Butterfly and The Dolphin (IC1318A). Also have a go for the Propeller. Interesting account concerning the Tulip to. In the fullness of the session, you certainly got to explore a wide range of targets and yes looks like you ended up with dank issues to.
  7. Yes the NAN is a fascinating complex area, an exploratory personal favourite.
  8. Interesting exploratory observations Gerry, the Propeller; Simeis 57 in Cygnus, did you attempt using varied filters? It does appear that it will be difficult if you haven't encountered it, I understand that a H-beta responds best to the 'brighter' northern placed strand DWB119. That certainly rules out any chance that I may have encountered it the other night, would have just been a more northern feature patchwork from IC 1318A. Good combination applied to the Crescent. That is interesting concerning the Little Veil; SH2-91. The Little Veil itself is on the cusp of eyepiece visibility, images do show a faint curved streak just above the main filament. Then to the N/E there is a faint patch classified as SH2-94 and directly above SH2-91, a fairly substantial long streak SH2-96. The characteristics are uncannily similar to the famous Cygnus Supernova Remnant. That is also interesting concerning the Tulip. Hadn't so far been able to locate this, stumbling onto it might probably have been the best thing. Interesting to learn that a UHC is good to enhance this object, I think a Lumicon Deep Sky Sky filter is purposeful on this to, I do not possess one and don't think that many of us do. If I got another chance to get out, not looking too promising, I would like to try a H-beta filter on the Butterfly Nebula, which is meant to enhance the nebula a little more from the glare of Sadr, also apply to IC1318A and yep why not the Propeller, but I don't expect much there. The Tulip though, I think Neil's had a go at this, would be good to target based on your description.
  9. Depending how long you are there for, Monday night might be clear, possibly tomorrow, Sunday, night. I was observing near a place called Stonehaugh Wark forest Thursday night south of Kielder and it was fine but no breeze, condensation became a problem. At least it looks like the midges have gone, or at least less of them.
  10. Very much as John has referred to here; the potential to see things that could not be seen before. This would mostly apply to dedicated galaxy cluster hunters, an 18" plus dob would become desirable. For most everything else, a moderate size aperture dob or other scope type would be applicable. Therefore it is perhaps determined by the type of visual observer you become in terms of what you specialise in observing or else if you are looking for an 'all round' aperture point. 10", 12", 14", 16" are popular and make a lot of sense, equally an 8" dob is a good all rounder. I like to focus attention upon large diffuse emission nebulae, balancing focal ratio with aperture is a consideration. Equipment evolves to best reflect your observing criteria. Being able to observe in good quality dark skies are far more significant, if you are a deep sky observer, than a notion for aperture fever. Can appreciate that is definitely a hand full and with the uncertainty of high haze and midges on arrival. We are certainly a bit crazy, but nonetheless committed. I hauled my 14" dob into the car on Thursday, the first time out, I later learnt, with it since mid January. This year of course has and continues to be unpredictable and restrictive, yet once set up I felt that I started to relax and the time between just melted away. Gaining in aperture definitely evokes a balancing appreciation for small refractor, binocular observing.
  11. I had misquoted IC 5070 (Pelican Nebula) referring to to this catalogue number twice, Just corrected the referred number to include IC 5068 below the Pelican.
  12. Yep, accumulated experience, consistent research and evaluation on different targets and going back to them time and time again over many seasons and the main ingredient dark and transparent skies. It is perhaps more of an attitude that shapes the way we see, that can fine tune our senses to be receptive to a specific subject. As an example, a plumber or an electrician can enter a building and they will through their professional experience and training, mentally see all the pipe works, electrical circuits that to ordinary people are hidden. Another example, when I was studying visual art at college, I would consistently pass by the everyday urban things and would subconsciously be mentally inquiring an aspect of somethings proportion, relationship to objects around it, kind of drawing it with my eye, simply because that's what I was doing everyday at college. If we become conditioned to something, then our minds eye will allow us to visually register that something that we are adept at pursuing. Increased visual integrity is also a product of the interactions on forums such as this, problem solving, resolving, clarifying. It is then possible to grasp an enhanced perception of a subject and that subject may gradually over time transform to become more vivid. A classic example is the Horsehead Nebula, my first encounter was with an experienced observer who could see it and even said that it is the best view he had ever had of it and through my scope, which of course I was accustomed to. However, could I and a club colleague with me see it, no it was invisible never mind the best view ever. A few years later and it has become straight forward, with an applied technique that is dependable and visually sincere.
  13. Interesting session, venturing to dark sky locations is a procedure of trial and error that can have surprises. For that reason, I do get a bit anxious when venturing to somewhere new, as was my circumstance last night, which worked out OK. Sky Quality Meter readings are invaluable. If the online resource is believed, it is somewhere in the region of 21.7 - 8. The reality is that it was just hitting 21.00 mag, though was specific for this particular night and time frame and will seasonally vary. I do have a rule that I will not drive more than an hour from home as a kip in the car is not my cup of tea and one hour is OK to pace back when tired. Therefore somewhere between 21.01 and 21.04, in average based meter readings, is usually where I get to, unless an overnight is planned. Always nice to encounter nocturnal wildlife to, except of course for midges. Taking multiple layers to gradually climb into is part of it, looking a bit like michelin man by the time you are fully kitted out.
  14. Good varied account of your session. The North America Nebula can be impressive, but it does require dark transparent skies and best when almost overhead. It would appear that you are getting there, if you can get to a darker location, with a reclining chair and your binoculars, with a method to steady the filter, you may be able to enjoy gaining more from this observation.
