  1. Lovely wide field capture, collectively they each resonate clearly Neil and is relatable to observational circumstance. Perhaps next time post on Imaging Wide Field, may pick up more response for developing this further, which based upon this outcome will be interesting.
  2. Yes I agree with that and also as you mentioned to take a succession of three readings and base on the average. Not having a SQM-L device at dark sky locations, to determine an accurate sky brightness assessment, is a disadvantage in my opinion.
  3. Don't worry a good secluded place you will likely have to yourself, somewhere else that might have someone unwelcome turn up, quite possible you might frighten them off, just for being there.
  4. Hi, I approach this region from the southern end, living in Newcastle Upon Tyne. I do not venture as far as the Lammermuir hills, remaining mostly in north Northumberland close to the border, I am also very attuned to Kielder and the skies here. Similar to yourself, approach this from an activity perspective, my primary interests are cycling, hill walking and I have a familiar knowledge for parking areas, pull-in's on quiet back roads. You may well gain a hunch to somewhere visited in the daytime that feels comfortable and welcoming with maybe no problems if you venture there at night. Going independently to dark sky places is an adventure in part for the unknown and for the potential encountering magnificent skies. It can be trial and error yet I would expect that your intended location, the Lammermuir hills will provide some good places and others may be able to offer more specific places. Its an excuse to study OS mapping at any rate. An 8" scope is a great tool to take out to darker skies, it will be easy to manage and will deliver impressive observations that are improbable from light polluted zones. Going to dark sky locations can be an infrequent pursuit yet it can become habitually addictive. One final thought, if the nature reserve parks (with large carparks) are anywhere near urban areas they might be best avoided as anyone else showing up late on is maybe unlikely (but not improbable) to be either an astronomer or photographer.
  5. Another finely executed set of drawings Miguel. Resolving each of the Messiers with your 8" scope will be an absorbing pursuit. There was a member on here a few years ago; Mike73, who posted up sketches of the Messier catalogue. They became a good reference for new members and for seasoned members alike. Your drawings and descriptions would in the same way be equally valid.
  6. Pupil dilation, I do not know, having never measured my exit pupil, to what extent my pupil will become fully dilated when my eye has achieved complete dark adaption at a dark sky location. I do understand that in visual adjustment, as the cones, that are colour sensitive, run out of light, the pupils will become fully dilated and the rods respond taking over more. This winter season, I had the opportunity to employ using a new eyepiece that provided an exit pupil of 7.73mm, with a Paracorr attached to my 14" F4.6 Dob. Selectively there were particular subjects I aimed to apply this to. Highlights included Andromeda, The Pleiades but two subjects in particular, that in the former were greatly enhanced and in the later revealed with certainty than previous attempts and much more extensively. They were The California Nebula and Barnard's Loop. Each required using my traditional 2" Lumicon H-beta filter. The aggressive nature of the filter complementary to the brighter contrast set by the eyepiece. The eyepiece is a 41mm Panoptic, which I took a punt on last year and has now become a go to for both my dobs and refractor. As someone who is not of much understanding regarding the science, some of the in-depth information on this thread has been of interest, yet actually applied 'in the field' at a dark sky location, yields interesting and successful results.
  7. Biggest concern in terms of the natural world for the UK are ticks. The answer is to reintroduce the wolf to cull the very oversized deer populations that are a carrier of ticks. Hill farmers aren't at all keen and successfully led to the blocked reintroduction of Lynx - let alone Wolf into Kielder. Sorry way off topic; dwindling dark sky a good rousing topic.
  8. It makes for a good conversation point even on a sunny May day with increasingly diminishing astronomical dark sky. A good quality H-beta filter is worth while long after the allure of the Horse Head has been realised. The California Nebula is a superb target in the right circumstances and recently I have been able to explore more extensively Barnard's Loop, another tricky subject, just different.
  9. Yes that is a point Steve, Neil whom I mentioned earlier is better located observing from the flat plains beyond Norwich. I tried to have a go for this from a fairly lofty hilltop location, wild camping, but unexpected cloud spoilt that. Barnard's E, west by north west of Gamma Aquilae, as mentioned by Gerry, is more feasible but still can be tricky, requiring very good transparency. Sweeping through the Summer Milky Way field particularly within the Great Rift with binoculars or rich field telescope, would be a soothing introduction to the complexity of dusty dark clouds. Perhaps, so that you can get a good commanding view of the Milky Way, could you grind a little bit further north on the M6 towards The Northern Pennines. Somewhere with a good view of the Summer Milky Way, killed off in most instances with our silly urban lighting, is a truly absorbing sight.
  10. Here is another sketch from Cloudy Nights indicating the notch that is more commonly seen by observers.
  11. Here is a picture as links not responding also a picture, correct orientation for dobsonian location of B33, Mel Bartels.
  12. Another dark nebula you could try and have at a go at Steve is Barnard 86, The Inkspot Nebula, coupled with open cluster NGC 6520 in Sagittarius. Here are a couple of detailed accounts and observers sketches and @Littleguy80 Neil, who has dedicated some observing time to this may chip in. http://www.perezmedia.net/beltofvenus/archives/000581.html https://stargazerslounge.com/topic/279188-sketch-ngc-6520-barnard-86-from-the-mercator-observatory-la-palma/
  13. I had read that 24" is possible yet at entry level in aperture terms, dependent on very good transparency. Visually engaging the Horse Head isn't a challenge, its a set of learning principles.
  14. Mine are preoccupied doing a 1000 piece jigsaw and I made tea tonight so they are quite happy for now. Not much more to include based upon the advice already presented. This had been said in other threads, so not entirely my own. M1 in Taurus is a good target to concentrate on before moving onward to the Flame and potentially B33. It will enable you to visually engage with a relatively bright object whilst gaining in dark adaption and responding towards stepping into more faint and diffuse territory. In our traditional photon gathering approach to detect the Horse Head Nebula, it is crucial to learn and memorise the exact location and correct orientation. There are very good online resource references from dedicated observers drawings and using dobsonians to print out, I may include one or two later. Unlike most other dark sky subjects, the Horse Head is considered on the margin of visibility, to encounter it at all requires certainty that you are located corrected and you know what to look for. Assuming all other circumstances are in motion, such as Orion is high in the south etc, averted vision is the key to seeing the nebula 'pop'. Therefore become relaxed in posture, patient and permit your eye to fully engage and relax. When you have seen the Horse Head Nebula, you will know it and you will be able to see it again and again. The larger the aperture the better the chance. Good luck for when the time comes (I don't blame you for planning for later in the year) and I hope that it is nothing like as dramatic as the the first time I encountered it. That is to say I just 'got it', when all of a sudden a car turns up, pulls into my remote small parking area, steps out puts a flash light onto my face. A local curious Police Officer, good banter followed and a sky tour but blimey what a way to kill off your first Horse Head encounter, I had to wait an age before I got another chance.
