  1. The Orientale Basin was immediately impactful as soon as I was able to begin observing, which was quite late. It is very distinctive, smooth, polished elongated and then those long mountain walls Cordillera and Rook mountains running parallel to each other, fabulous to observe. Yes again thanks for the heads up. Also what I believe to perhaps be Drygalski, an older Copernicus twin, revealed in glorious contrast on the limb just due west of south. Quite a spectacle with its central peaks protruding. 'Atlas of the Moon', my Astronomy Now Moon poster and 'Sky & Telescopes Moon Map' each assi
  2. I have been using my 8" dob on the Moon quite a bit recently, in fact just about to go out, as soon as it clears the chimney stack. Typically I may start at 66X and work my way up, settling usually at 171 - 240X. Never actually occurred to me to use a filter, particularly if its a dedicated Lunar session, your pupil quickly adapts and as mentioned. mid to high power creates more tone anyway. Also often, the Moon may naturally become slightly more reduced in brightness due to thin cloud passing over. In as far as detail is concerned the 8" dob will enhance many extraordinary features.
  3. Cheers, got the location on my chart, hauled the dob back out for (much) later.
  4. Quite a night. Interesting to capture the subtle and strange light toned feature of Reiner Gamma and prominently lit along the terminator close by I think was Glushko, Olbers, Hendin. Referencing 21st Century Atlas of the moon, was great to see the Kraft crater chain aligned with Cardanus. Higher up, Pythagoras and its central mountains were prominent, moving down Struve, Eddington and downwards I think Schickard. Always an education, the references gleaned from here and knowledge through books and charts make it very stimulating. Was able to go up to 300x, but 7mm; 171x was most satisfying.
  5. Thanks, I wasn't going to bother until I read this, hauled the dob out for later.
  6. Excellent, will be good to hear how you progress with this. Very interesting nightscape photography and aurora captures from your coastal location.
  7. Could I also suggest that you contact Richard Darn. Richard was a key advocate for instigating the Northumberland Dark Sky Park status and was also a co founder for organising Kielder Star Camp. He also posts on here, but I cannot remember his user name. https://darkskiesuk.org/about/
  8. This is an interesting article that you could bring to the attention of the parish council. Concerning nocturnal impacts on Entomology. Those of us who seek dark sky environs are sensitive to the negative impact and ecological harm that local light intrusion and the relentless creep of light pollution creates. https://www.ncl.ac.uk/press/articles/archive/2019/01/streetlighting/
  9. It can be surprisingly difficult to get completely away from, although on atmospherically dry nights, it becomes less noticeable. Newcastle Airport is a concern, extravagantly lit up. 21.00 Mag / NELM 6.00 is considered entry level for good quality dark skies. Northumberland Dark Sky Park status and dark sky tourist industry does promote, within the park boundaries, awareness for regionally appropriate lighting, reducing unnecessary light intrusion. You mention the coast and I agree, the closest, easterly location I have used as mentioned is near to Thrunton Crags, nearest Town is Alnwick, whi
  10. Hi yes the SQM-L is the best tool to have and will require a succession of readings over a clear transparent night at a particular location to gauge an average magnitude read out. Even then it can vary, as mentioned from the same location on alternate nights. Early morning is usually best to gauge an optimum reading if conditions are applicable. I have roamed many potentially dark sky locations in Northumberland. These include the Breamish Valley just on from Ingram (very good for taking readings), on the same approach, a location near to Thrunton Crags, west over at Cawfields on the Wall and
  11. Clear here and yes Gassendi in particular and Schiller were each very imposing. The light began to filter down, revealing aspects of the terraced walls of Gassendi, conveyed in the 10mm Delos, 7mm DeLite (using an 8" dob).
  12. Perhaps loyalty but more so becoming parfocal, such as interchanging amongt Delos and DeLite focal lengths.
  13. I think as Paul says, 14 or 12mm Delos could be a strong contender at that focal length range. I only currently have a 10mm and have owned a 6mm, each very comfortable eye placement, as mentioned crisp image right up to the field stop.
  14. Hi and welcome to SGL. As John mentions, 12" is a good and manageable size, yet going bigger, well why not. Someone who went big whilst starting out went particularly big; @Ships and Starshas a 20" Skywatcher dob. Also a more 'grab and go' 12" version, each I believe he purchased used. Personally I have two, both are manual tracking, an 8" which receives the most use and a 14" notably for dark sky trips - which have been few and far between this past year. Manual tracking, equatorial platform assisted tracking, or full goto and auto tracking is personal. My preference is simple, manu
  15. Excellent report Gerry; Polar Vortex, Timber wolfs, The Rosette Nebula what a mix, stimulating read and 'Neek' is growing accustomed to your environment well. Could be the closest many of us get to the Rosette this season, travel restrictions, now we are into the 'great thaw', perhaps @Ships and Starsmay get a shot at it. However it is good to reminiscence on past occasions, such as a report from not sure when 'I hastily refitted an OIII and swung the scope around to observe the Rosette NGC 2237, the immenseness of nebula cloud enveloping around open cluster NGC 2244 was a fine sight unti
