  1. That is an informative - revised up to date article by Mel Bartels Gerry thanks. Integrated Flux Nebulae, we had discussed this at length before a few years ago. I think back then I recall having a good go to trace the IFN that is in the vicinity of M81, M82 and sensing at the time that in the right circumstance and based on Mel Bartels drawings as reference it was possible to visually detect, at least aspects. At the weekend it was the Pleiades Bubble that with conviction was visually apparent. I did not study this outer area too much as I was more focused on the immersive Merope and associated nebulae. The large exit pupil 7.73mm / 1.4 degree field, coupled to the excellent transmission of the paracorr enabled these features to become quite bright and engaging. Perhaps something to consider exploring for again on dark sky trips and consider aiming to detect the spur you had described near to Vega.
  2. Glanced at the title Stephan and initial thought is Penguin? Then quickly recall that you had used this title referencing the Newtonian in previous accounts. Cold night, sounds like a good idea to had set "Blue Penguin" up on the sideboard looking out. It is nice to coast through the open clusters, I found this to be really relaxing on the second part of my night out on Saturday including the ones you mentioned with my 85mm refractor. Nice to, to complete with that galaxy.
  3. They would make a meal out of the Double Cluster Or you could chew your way through Andromeda Or perhaps sink your teeth into the Beehive Cluster (Sorry)
  4. Quite understand Neil, when you describe the density of nebulosity and rich surface texture conveyed within the California. It is subtle but it is emphatically there. I took a look at some of the recent images of the California when I was reflecting on this and descriptively, though the observation was relatively dim, was quite comparable to my recollection. It is / was the perfect time to observe this subject. Your 40mm Aero is clearly a superb eyepiece to. Anyhow that is great that your club has some dedicated observers and companions, enabling you to advance your observation skills yet further.
  5. Yes its quite easy to read the landscape when you are dark adapted, just off in the far distance occasionally there might appear a flare or two, Otterburn military training camp, not directly encountered any pursuing squaddies so far, at least whilst out stargazing. Aye glow in the dark tape, I probably have some spare luminous tent guy line around. However perversely it does ensure that I keep my wits about me, when I have the odd stumbling gaff with the chair. No harm done, walking into an open car door or particularly open car boot door has much worse momentary consequences as I have discovered. Yep flocking what you can of the inner and painting other parts with Krylon Ultra Flat Black paint can do no harm.
  6. That is a good point concerning using a large hood, this is something I haven't tried, I know that some on here with stray light situations use this method. I might take my hooded down jacket next time rather than my old down, non hooded, smock. Comfortable posture or seated position and becoming relaxed when at the eyepiece, is definitely beneficial, never forget my astro chair, only problem with it being black, I do from time to time stumble straight into it.
  7. Interesting account Gerry, the characteristics of the Merope nebula certainly respond to various focal lengths at low power, with a medium aperture dob. The Flame does seem to respond at varied mid power eyepieces. I used my 13E and 10D each conjuring a good balance between contrast and brightness, probably the Delos worked best for a narrower field of view, in my case more pronounced without a UHC filter. Would be interesting to use a 17.3mm Delos.
  8. Nice report it is a splendid period to be sweeping the constellations for open clusters with a pair of binoculars. M44 Beehive cluster nicely placed presently to.
  9. Just as with the three other response's Neil, cracking report, really good that like many others on here you got to be able to take advantage of that short clear sky window of opportunity. Setting up alongside your experienced observing colleague was understandably a good supportive asset. Good plan to start with the comet and onto those other targets and then to follow on to some of the more elusive subjects. It took a little time for myself to ease in to a systematic plan on arriving at my dark sky location, eager to get on after such a lengthy period of absence observing anything much. A similar pattern to my own encounters, exploring potential observations with a large exit pupil and filters with interesting results. That is also quite something now you can see the Horse Head without the aid of a filter, next step will be to pick out a more refined definition of the profile, which is completely achievable with gaining in familiarity and experience.
  10. There is always something that gets forgotten, regardless of how much detailed items you may have packed. However a superb and varied session Robert with an interesting comparison when using binoviewers. My quite exposed site was surprisingly wind free last night, good plan to use the van as a wind break. IC 405 is a nice target and as you mention, it is easy to slip into observing many of the close by open clusters contained within Auriga. I did not observe M42 and M43 until much later keeping with the particular dimmer subjects, when I did focus attention on the Orion Nebula, the intensity of colour and bright expansive nebulosity was very impactful. Skyglow when you are least expecting it can be alarming and vary throughout the session. At my location there is some in the south east, but as transparency improved it diminished, Newcastle Airport is the culprit which is stupidly lit up, at least the area is not in a flight path zone, just instead the occasional shooting star.
  11. Following a cold bright day I headed into Northumberland, which initially had become fairly cloudy. After sipping coffee in the car for a few minutes, was relieved to see the Milky Way and the winter constellations, brightly peppering the sky. I set up my 14" F4.6 dob alongside my Tele Vue 85 refractor. Three subjects in particular were objectively revealing tonight; The Pleiades, the California Nebula and Barnard's Loop. I would be using a 41mm Panoptic, that equipped with the a paracorr converting the dob to F5.3 and a super large 7.73 exit pupil. This would experimentally change the 'attitude' of both scopes particularly the dob, observing faint and diffuse objects. The Merope nebula was vast and the glow of nebulosity marked each prominent star. As in Gerry's report, there were detectable dark lanes and the Pleiades bubble abounded, with a glow of dust clouds around the cluster. Onto the California and this object lit up, almost comparable to a chunky version of the Veil, there was much billowing structure in the dimness. I have become accustomed to observing this object each season, the high altitude, combining the pan 41, paracorr and lumicon H beta filter, the image was the most revealing and defined I had encountered. After this at mid power I observed M1, to remind myself of the image scale and then moved down to the Flame, the dark lane particularly pronounced, I prepared to move on towards B33. Aligning that small faint double star behind the neck, sure enough the Horse Head could be discerned. In anticipation I continued to work with the Pan 41 and aligned onto M78. A slight movement of the scope and there it was, there was a quite definable edge line. marking the profile of Barnard's Loop. I have never seen this before, in the past I had entered into Barnard's Loop as a very dim grey curtain banishing the background stars, but here was an actually perceptual edge. I was able to work across and then aligning north a little and then south. Later using the TV 85, with the 41 Pan and H beta filter, I was able to drift along the curvature certainly south in alignment with Alnitak. The Pan was also, not so unsurprisingly engaging on Andromeda, yet becoming even more expansive. Later unfortunately while examining the Hour Glass Nebula, the focuser became very slack and I did not have the tools to hand, so retiring the dob, packed it away. However it meant that I could continue with just the TV 85, re-engaging with much besides such as the Eskimo Nebula, the Orion Nebula, Rosette Nebula and Barnard's Loop, the California and the Pleaides which in this refractor, begins to reveal the Merope nebula at mid power and not at low power. A tour of open clusters concluding with M41 the Little Beehive completed the night.
  12. Thanks for posting that image of the Pleiades Gerry and thanks @Buzzard75 for allowing this image as illustration, which h is excellent. Bright cold clear day here, loading the car and now I have this impression on my mind cheers.
  13. Great, nice account Gerry. I look forward to hopefully sampling some of that this weekend as high pressure is forecast.
  14. I'd better, belatedly, rephrase that then. Wae'aye, me to, am even beginning t' accept me wife's term "the junk corna".
  15. I think as said, if it were possible for you to link up with / collaborate with an experienced mirror maker, perhaps to learn the skills or at least mentor, then it may be a more reassuringly potential, if the cost were acceptable, venture. In terms of seasonal, well, I would pitch at all four seasons, the weather and all that being the way it is. Sometimes members at astro societies, experienced observers, may get together to build a large club dob, although the mirror would be often sourced elsewhere and collectively there will be the finance to invest in going ahead with this type of project. You definitely sound like someone who needs a project though. Perhaps if the truth be told, life has many obligations and complications, family of course, work, weather health etc; yet if and when we find ourselves next time at a very dark place on a cold winters night just getting on with observing, the rest will be washed away, forgotten.
