Title: Newbie seeking advice on a handful of topics: light pollution, eyepieces, and fi
Post by: Cesar Lawhorn on December 27, 2017, 12:01:54 PM
Hi!

I'm brand new to amateur astronomy, having just acquired my first scope - an 8", f6 dob (XT8 Plus, specifically). I've taken it out every clear night and I'm already sure that this will be a hobby I will be investing some time (and money) in. I've spent some time reading through these forums, and have read through two highly recommended books ("Nightwatch" & "Turn Left at Orion"), but there are some things I could use some further advice on:

1. Light pollution: I live in an urban environment (Alameda, CA - basically downtown Oakland) and the light pollution is awful. I have 3 young kids, include a 1 month old, so my ability to get away from home to seek out dark skies will be limited for the foreseeable future. I understand that many deep sky objects will remain out of reach from my location, but I still want to seek out all the open clusters and multi star systems and any other bright objects that I can from my own backyard. Considering my gear, and that I have no GoTo technology, I'm reliant on star hopping to find my targets, which is quite difficult with my severe light pollution.I had considered getting an extreme wide angle eyepiece at low power with which to break through the pollution to navigate the skies for star hopping purposes.Is this a feasible solution? Perhaps coupled with a broadband filter?Any other advice on star hopping in severe light pollution without GoTo technology? Also, can you please recommend a resource for light pollution maps?

2. Filters:I'm considering purchasing two different filters, a broadband filter to dampen light pollution (noted above - although I question how helpful it will be), and a narrowband filter for nebula viewing from home and on rare occasions when I can get away from the city. Regarding the narrowband, I've read great reviews on the DGM NPB, so that's currently at the top of my list. With that in mind, I'd rather not pay the full $150, so I'm mulling the idea of getting the "cosmetic 2nd" discounted piece from Amazon (http://www.amazon.co.../dp/B00MLHQW7K/ (http://www.amazon.com/DGM-Optics-NPB-Nebula-Filter-Cosmetic/dp/B00MLHQW7K/)), but I'm concerned about the fact that the flaws include "cosmetic flaws, such as pinholes, sleeks, or light scratches". Are these flaws significant when it comes to filters?Or should I trust DGM when they say "flaws which have zero impact on optical performance. Spectral characteristics are the same high quality as our first quality filters and side by side performance is indistinguishable."

3. Eyepieces:There's so much information out there on eyepieces, it's difficult to settle on which eyepieces to target next. The XT8 Plus comes with an Orion 10mm plossl and 28mm "Deep View". The plossl seems well enough for now, but I don't feel that the Deep View provides enough FOV for a lower power eyepiece, so I think a low power, wide angle eyepiece will be my next purchase.With that in mind, any recommendations on the ideal "True FOV" to shoot for low power viewing? I know 2"+ will be necessary to take in all of thePleiades and Andromeda (for example), but is 2" considered overkill, or is this a good TFOV to shoot for? Any other eyepiece advice you can provide regarding building a strong initial eyepiece set would be helpful as well (considering mid to high-tier options).

Thanks a lot!
