I've upgraded my focuser so have a Skywatcher Dual-Speed Low Profile 1.25/2" Crayford focuser for sale £70 delivered to UK only.
Bank transfer or Paypal F&F preferred.
Wrapping up in double layer goose feathers I braved the obsy last night. I planned a tour of Auriga with a view to chucking in some favourites. I set up the ED150 on the AZ EQ 6 and fitted the WO quartz diagonal accompanied by my ES 20mm 82'. I stuffed my Astronomik 1.25" UHC (bargain price thanks @FLO) in my pocket too. This set up required the retro children's playroom chair with the legs sawn down due to the position of Auriga. I spent about half an hour checking the plethora of open clusters sprinkled in or near the Milky Way. The sky was one of the best this season so it was a jewelled spectacle and the ED150 reveals such sharp colours enabling me to distinguish the cooler stars in some of the clusters particularly the occasional red giant. As Monoceros reached the meridian I moved to the open cluster associated with the Rosette. Now, for all my efforts over the years, the emission nebulosity has eluded my eyes but tonight with this newish 6" frac I was somewhat taken aback to see a doughnut appear in the view. Switching to a view with the UHC filter was nothing short of astonishing! It wasn't just there; I was falling into its centre. Texture, depth and dark globules were easily discernible. The extent was slightly larger than the FOV with the 20mm so I slewed slowly around and the perimeters and varying consistency of the Ha emission were easily picked out. I spent a long and happy time soaking this up; it was truly outstanding. Thoroughly recommended. I retired happily to the warm kitchen and toast.
I just installed this Lacerta 1:10 Micro Transmission focuser on my 8” Skywatcher Dobsonian. It is a direct replacement for the stock focuser and works extremely well. I was surprised at how easy it was to install! Ordered it from 365Astronomy and got fast shipping.
This is probably my options as of now:I will definetly buy a 12mm BST Starguider A 2X BST Barlow( So thats 100x and 200x magnification)
15MM BST STARGUIDER VS 25MM STARGUIDER
My dobsonian telescope will include:A 25mm and 10mm Eyepiece . So the obvious awnser is to go for the 15mm BUT i ve read in reviews that the bst s have are noticabely better than the eyepieces that come with my telescope.So i am wondering, should i buy the 25mm or the 15mm BST?
Also is it worth to barlow either 25mm eyepiece to make 12.5mm and ditch the 12mm i am definetly buying for a 6mm one? i am thinking not because if i barlow the 6 mm it will give me 400x and i think that is too much magnification for the image to appear clear , plus i will also barlow the 10 mm to give me a 240x the acceptable limit for good clarity / magnification ratio (i ve read that and not sure if its true or not). Thanks again for your time and help!
This forum has been very polite, welcoming and kind to noobs like me just getting into the hobby XD I hope i can one day look back at myself and laugh at my ignorance! This site has been truly amazing and i hope i can stay a member for a long time to come!
Thanks as always
Clear skies everyone
