  1. What I have learnt in pursuit of this, is that the contrast needs to be just right. F4.5 might be slightly disadvantaged at 8" and with a wider field, which will already be difficult. Equally very dark skies, I observe in SQM readings of 21.3 + and always restless to gain an improvement, very good transparency and complete dark adaption (so as far as possible no red light either). Time spent on other dim and challenging objects is also required as a lead up. Eyepieces can vary, I regret at times not holding onto my 20mm nagler, which was very capable on this, my 20mm TeleVue plossl 4.34mm exit pupil performs really well on identifying each component, NGC 2024, IC 434, B33. Training your eye, employing averted vision and understanding correctly the star-field and a good dollop of patience also necessary, as is a good quality H-beta filter. Another eyepiece considered very effective at moderate aperture (between say 10 and 16") is the 19mm Panoptic. It is an alluring if slightly ludicrous object to become obsessed on really, but one in which many including myself find compelling and like to try to visit each season.
  2. Not improbable to observe in your 8" F4.5 scope, though it might become a little easier if you could gain an opportunity to first see it in a larger scope perhaps 12, 14, 16". It is an object that feels challenging to begin with until seen with conviction, after which it almost becomes something that you feel accustomed to seeing. Gaining familiarity on difficult subjects with a larger scope, injects confidence and eases the observation process when returning to these subjects using a smaller aperture. Quite as others have said, focus more on observing with some clarity the Flame.
  3. I recently let go of a 25mm TV plossl, it was probably the weakest link in my collection, purchased to assist in hunting for the Horse Head nebula, I arrived at a conclusion that my 20mm actually performed more effectively on this subject. Since selling, I have had moments thinking just maybe it might have assisted for this or that specific target and is / was a nice eyepiece. The cash injection was welcome, otherwise perhaps best to hang on to a valued collection.
  4. Absorbing read, very nice report John, Thursday was clearly this months defining night for many to go out observing. It can become a pleasant feeling of contentment, following a fairly lengthy period of observing, submitting to fatigue, yet knowing that the sky you are leaving behind is still tempting.
  5. Night of the Nebulas

    Very nice report and good read (the title, make a great retro 50's B movie). Personally particularly interested in your observation for IC 1396 and account for the Heart and Soul. The California will become engaging to observe when culminates (I use a H-beta filter on this). Thursday night became and remained clear here to, good that you were able to take advantage. The build up of condensation always knocks me off guard to at this time of year, on my recent trip fortunately a breeze built up through the valley as I did not have my battery, hairdryer etc. Layers yep I was back up to four, the outer being my down vest, also sported my new down filled beanie hat for a time - whatever happened to Summer.
  6. M110 Finally Nailed!

    That's great, having accomplished this, you will expect to see M110 each time the Messier Andromeda group is observed and at least your neighbours don't keep any lights left on after they turn in for the evening.
  7. Veil,Sh2-91

    Very fine conditions to observe in following that thunder storm Gerry. Interesting descriptive account. Also concerning the Little Veil, that is reassuring that you were able to repeat this observation and with a degree of clarity accounting for its challenging nature, in the right circumstances, continues to be something I would like to try for.
  8. In Pursuit of Barnards 142 & I43

    Thanks everyone Yes that combination would be highly applicable next time Gerry. I parred back the kit I might otherwise had taken, opting for a kind of 'rapid reaction' approach, the VX8L required minimal modification to the car, taking a punt that the forecast would stand correct. Quite some time since I had last been able to sit out and gradually watch the stars appear, void of any big ugly clouds preparing to lumber across. Along with forum members accounts, there is plenty of informative concerning B142 and 143, not least on Cloudy Nights. Here is a, familiar to many, feature in this observers resource. http://www.perezmedia.net/beltofvenus/archives/001379.html
  9. Edward Emerson Barnard published his listing of famous dark nebulae in 1919. The pairing of B142 and B143 (Barnard's E), are contained in Aquila, three degrees N/W of Altair and within the summer Milky Way star field. Dark nebulae are clouds of non luminous dust and gases that obscure the stars behind. B143 and 142 are considered an easier and equally impressive phenomena, within this class of nebulae, to seek out. The defining feature is the E in B143 (which I believe is also known as the Triple Cave). The nebulae are large in scale and so require low power and large field of view and can only be observed from a dark sky location when the Milky Way is clearly distinguished. I was not necessarily best equipped to observe B142 & B143, omitting to take along either my 16x70 binoculars or 76mm wide field refractor. I was though fortunate to be out observing at all, with a clear sky forecast anticipated until midnight. I took along my 200mm F6 dobsonian for low power wide field sweeps of primarily large emission nebulae. As darkness began to fall, M57 and M27 became a welcome sight, their familiar characterises pleasing to the eye. I repeatedly visited each planetary time and again, as I did many of the objects observed, throughout the session period. As it drew yet darker, I eagerly applied attention to the Cygnus Loop. East and western veil, Pickering triangle distinct and enjoyable with both my 31mm and 21mm ultra wide field ep and OIII filter. Switching to my Lumicon UHC, I located IC 1318 in the locality of Sadr. Along to the North America and Pelican to enjoy mesmerising views, I drifted along towards 68 cygni in pursuit of Sh2- 119. I think I can detect nebulosity but is faint and so kept trying throughout the evening. I observed many other objects switching between filters and none, such as the Crescent, NGC 6826 Blinking Planetary, M71 in Sagitta. The Milky way was arcing brightly across my location, observing conditions were generally good with an average SQM-L reading of 21.3, condensation that had started to build up was now kept at bay as a gentle breeze had picked up through the valley. It was a no nonsense approach for B143, 142, my 31mm nagler providing X39 mag, 5.1mm exit pupil, potential 2.12' field. Working along from Tarazed, I could imply the dark voids and spaces in an otherwise intensely compacted starfield, quite compelling. My field of view range was perhaps not really enough to fully encapsulate and appreciate this encounter and perhaps I also need to (as I have upon returning) fully comprehend what I am looking at. Therefore I will visit this again with a much clearer understanding to fully grasp the defining features, something I look forward to. IC 1396 Cepheus was also a focus of attention, although at times I found myself floundering in the dob hole. Fixed on the Garnet star, I could drift across to reach the large emission, IC 1396 The Elephant Trunk nebula. With conviction I was able to drift along the meandering length of this expansive feature. I believe that a dark nebula is also prevalent and like so many other circumstances, to research further and anticipate visiting again. I just managed NGC 7325 the Little Ring Nebula (a dob hole negotiation) when cloud was threatening from the West. I therefore left emission nebula sh2-132 for another time and turned towards Cassiopeia. Positioned on the Muscle Man cluster (Stock 2), I nudged the scope towards NGC 896 in the vicinity of the Heart nebula. Again I determined that I could discern nebulosity yet need to confirm and understand the visual implications (which I believe the brighter area might be quite compact and small). However with not much time until cloud finally encroached, I removed the filter to enjoy a high power view of NGC 7789 Caroline's Rose. A barn owl stood planted in the road, contemplating its meal in the undergrowth, it swivelled its head to regard my passing, so nice to be out again.
  10. Really inspired by this Piero and have been planning for some time to take my TV76 on a short backpacking journey to wild camp up a small hill, on the approach to the Cheviot hills and so gain the darkest skies possible to strain this aperture. I do not have a wholly portable set up, though most suited for car boot camping, yet portable i.e. berlebach tripod with shoulder bag, to carry in one easy journey to an allotment from time to time. With a more compact kit, a cycle trip will be tempting.
  11. I like Charic's dob tent Here is my dob cage
  12. NAN to LBN 365

    Trust the aurora to put in an appearance, very nice sky cruising session Gerry, particularly concerning the description of the bridge. Solid cloud and a threat of rain here, cant last forever.
  13. Is the UK getting more cloudy?

    First time in a few years that reaching mid September, I have not so far this season observed within the Summer triangle. I had become quite switched off for much of the summer period and getting into other activities and occasional clear nights during work day evenings have not been motivational enough to get out into the yard. It is disappointing that the weather lately has been poor, cloudy with rain night and day in the N/E, as I had been looking forward to a dark sky trip (last trip out for August new moon turned into a dud) that may not happen, particularly as I am self employed and typically have phases of quiet week day periods so can potentially take advantage of a new moon. Still I guess lunar observing from home with binoculars will soon enough suffice.
  14. In-between you two guys with a TV-76, I agree with all the comments. A short wide field refractor has a very prominent place, though not necessarily as an only or even first scope. Visual astronomy may be more fully regarded when combined along with a 8-10" dobsonian and pair of binoculars. My TV-76 along with my other scopes and for the usual reasons, hasn't been outside for a good while, though for its portability and ease of use I have in mind a few planned outings that may transpire.
