  1. A 42"/107 cm Dob in Germany : http://www.herzberger-teleskoptreffen.de/news/ds06.php (English text and pictures in "Dobson-Teleskop") Stephan
  2. Under 5.5 mag/SQM-L 21.1 skies, I've spotted M 33 repeatedly with my tiniest optical device, a Docter 6x21 monocular (excellent optical quality - Zeiss). 130 mm aperture are more than enough under decent dark skies; give it a try, and have patience; good luck! Stephan
  3. As a rule of thumb, a reflector telescope (Newtonian, classical Cassegrain) will need about 5 minutes cool down time per inch of aperture; a 41/2" approximately 20 min. , a 10" almost an hour. That doesn't mean, that you cannot observe within this time - use low powers to sweep star fields and open clusters, or start star hopping to your target of the night. With progredient cooling, you can use higher powers. Storing your scope at ambient temperature (garage; garden shed; barn etc.) eliminates any cool down problems. Stephan
  4. When using the Light Pollution Map, you can enable in the toggle menu "feature", and in this the options "SQM" +"SQM-L". You will now find in the map, shown as coloured circles, a whole bunch of SQM/SQM-L measurements by amateur stargazers, that represent the more accurate "down-up" perspective. You can add your own measurements as well. A lot of gaps between the different places, but gives a rather realistic view of the local light pollution. Stephan
  5. Not cheap, but might be a lifetime investment: https://www.teleskop-express.de/shop/product_info.php/info/p891_Tele-Vue-Astigmatism-corrector---0-25-dpt---DRX-0025.html Stephan
  6. Welcome to this friendly forum, and the best wishes for your reconvalescence. To quote Marty (avatar "bumm"), CloudyNights forum : "This hobby has thrown me a lifeline during much worse times of my life. What would I ever have done without the stars?" Stephan
  7. Coloured double stars have been mentioned above. You might also give the Carbon stars a try, that shine in various pink-orange-red hues. Herschel's Garnet Star; Hind's Crimson Star in the constellation Lepus south of Orion (deep red - the "Vampire Star") and La Superba in Canes Venatici would be great starters even under light-polluted skies. There are various lists in the net. Stephan
  8. Two nice reports, orions_boot, that show your growing enthusiasm and skills very well. The star fields you memorize now will come to good use later, when using a (finder)scope. A 10x50 is a lifetime companion, complementary to any scope. Btw., have a look at the wonderfully deep orange star TX Piscium, in the eastern part of the Pisces "circlet ". The colour of this 5 mag star is a joy to behold in my 7x50 Fujinons. Stephan
  9. You haven't to wait for the perfect skies. Was just out under very hazy skies, NELM 4,7 (47 Cyg close by), SQM-L20.85. M 31 near zenith barely visible. With the 8" f/4 and the ES 24 /82, together with an. Astronomik UHC, the Veil could be made out with direct vision (33x mag), even the fainter western part. Not much detais as filaments in the "claw", but visible as the well known arc, Stephan
  10. I had this in mind, Gerry, as well as Stu's report with the 72 frac, when I took out, just for fun, the "Blue Penguin", a 76/300 Skywatcher Infinity 76 N, to chase the Veil. Conditions were sub-average with a NELM of just 5.0 (UMi). I started, as usual, from 52 Cyg, using a Baader UHC, that fitted quite well into the rubber eyeguard, and could make out the eastern part, partly with direct vision, but clearly with averted vision, as a faint arc, without details (15x mag). Switching to 30x made the view too dim. Intentionally, I did not use any map, memorized the star patterns, and compared later to SkySafari - a perfect match. The western part remained invisible, due to the sky conditions. All this with a "children's toy scope" (-which it is not, it's with 15x mag and 3° TFoV a very capable and affordable RFT). So, all you users of small(ish) scopes - give the Veil a try! Stephan
  11. I' m using both Barlows, the legendary 2x Zeiss Abbe built to Zeiss specifications by Baader, and the 2.25x Turret Barlow. Both are excellent - you forget their existence, once inserted. To be honest, the 2.25x isn't much behind it's famous brother and works well with all my scopes down to f/4.5 ratios and all eyepieces. Very sharp, without edge distortions, neutral colour, lightweight. The 2x is slightly better with my 8" f/4; and I like the Clicklock for 11/4" eyepieces. You will not be disappointed by the very affordable 2.25x Turret Barlow. Stephan
  12. Spotted the Veil with the Heritage 130 P Flextube several times during the last three years. At least the eastern part was almost always visible, even under sub-average 5.0 mag/NELM 20.0 skies, through an UHC filter, in better nights even without filter. Good luck for the hunt with your temporarily available 130 P! Stephan
  13. Agree with John. 8" - 10" Dob, Orthoscopic eyepieces, UHC+O III filter, RDF/RACI finder combo, Interstellarum Deep Sky Atlas, SkySafari Plus. Decent observing chair, warm clothing, winter boots. Stephan
  14. Was out with the 18" Obsession this morning under hazy 5.0 NELM/21.1 SQM-L skies, prompted by a freshly released German observer's handbook "Beobachteratlas für Kurzentschlossene" to spot this chain of 9 members, close to Mirach. Starting from there, I was greeted by the very obvious and well detached galaxy NGC 404, "Mirach's Ghost". After a short star hop with the 18 mmf/82° Maxvision, giving 114x mag, the brightest member, 383 (12.4 mag), was immediately visible, almost round, with a brighter core region. N of it, the galaxy pair 379 and 380 (12.5/12.7) was obvious. The slightly fainter pair 384/385 to the south was visible directly, when I switched to the 10 mmf Zeiss Ortho. After several minutes, I was able to make out the much fainter 375 (14.3) to the west, with averted vision for about 30% of observing time. The fainter members remained invisible through the haze, but I'm sure, that they all are accessible under 5.5-5.8 skies. A pleasing view with 205x, and a rewarding target, for 12" or even 8" scopes. (Have a look at the Interstellarum Deep Sky Atlas, chart D11). The warm late summer night was enriched by the scent of several nightly fragrant flowers, that I had sowed close by. I don't listen to music, when I'm observing - too much distraction for me. But these little summer greets were a nice addition; and so, after 1 hour of observing, quite content to bed at 04.20 CEST. Attached a picture (from the net): Thanks for reading Stephan
  15. Have a look at this, a 150/750 Newton, Dobsonian mount: https://www.teleskop-express.de/shop/product_info.php/info/p12279_Skywatcher-Dobson-Telescope-Heritage-150P-Flextube---150-mm-Aperture.html This scope, a shortly released slightly bigger brother of the excellent Skywatcher Heritage 130 P Flextube, gets good reviews (do some research on here) Teleskop-Express will also ship to Portugal; a very reliable partner.
