Thank you Michael. Hope you find your new GNG scope a lot of fun. As you well know, no matter the
I see I missed your comment here Steve, my apologies. I appreciate your kind comments. Indeed there is a lot of information that could be in a primer for those getting ready to start. So much so I fear it might scare some folks away! As you, I and a lot of folks here now know, there are so many variables associated with visual observation that can make or break our endeavors. The beginner's learning curve is significantly steep, but through experience behind the eyepiece and a sincere desire to learn, we work our way through the trial and error process to become the kind of observer that we wish to be. By gaining a deeper appreciation and understanding of the objects we observe, we are encouraged to keep going back for more. I've always been fond of saying "the more fun we have the more we learn, and the more we learn the more fun we have." A bit of circular reasoning that I truly believe. :smile:

For those folks starting out, there is an understandable tendency to place too much reliance upon DSO magnitude. While for very compact DSOs that can be a bit more realistic, with extended objects like galaxies, relying too heavily on its integrated magnitude can give one a misleading impression of their visibility.
If I had a 17.5 I would also have a Skyshed Pod to keep it in at the darkest site I could access. so far I have looked through a couplekt4hx wrote: ↑Sat Jan 04, 2020 3:27 pm Thanks David. For these denizens of the deep, aperture and dark skies are indeed your friend. There are some brighter ones of course that can be seen in smaller apertures, and often visible even from areas of significant LP - or at least their brightest portion, typically the core. But there are far more that simply cannot overcome higher levels of sky glow and many more yet that are out of reach of small apertures. Given that they are far and away my favorite category of DSO, there is little wonder that I favor using my 17.5 inch at our dark site. It does in fact open up a whole new universe for me.
Thanks. I have no problems keeping it in the garage and rolling it out. The wheel-barrow handles make that easy enough even for this 65 yr old. I would imagine there will come a time when it will become more of a chore, but barring unusual circumstances, I don't see that for some time yet.

wow you can roll it out using the wheelbarrow handles. That sounds exceptionally nice. Thekt4hx wrote: ↑Mon Jan 13, 2020 3:13 amThanks. I have no problems keeping it in the garage and rolling it out.

TypicalSQM -L readings are around 21.3 to 21.5 (usually toward the higher end of that range), but have been as good as about 21.7. So I cannot complain in the least.
