I'm just getting started with compiling a collection of accessories to enhance my viewing. I want to add to the collection slowly, so i get a chance to learn from each new thing and use that experience to better inform the next purchase.
With that in mind, i was wondering if I'd be better served getting filters earlier or later in the process?
By filters I'm sure i don't really know what I'm talking about but i see on FLO a narrowband UHC filter (unbranded) and a celestron "CLS" filter - City Light Something, or essentially a light pollution filter. Both around forty quid, which is my budget. Both sound useful for me, I'm in a red zone (urban/ suburban). I'm interested in seeing more nebula - improving the Orion nebula, i saw someone said a filter helped them see the veil nebula with similar equipment to me in similar conditions.
So... any thoughts or advice? : )
i have an f/8 skywatcher dobsonian 6", with the stock 10 and 25mm eyepieces, and an 18mm BST StarGuider coming for my birthday... as well as an astro essentials moon filter and an astro essentials 2x barlow.
I am selling the following items:
Revelation Dielectric 99% Quartz 1.25" diagonal. The 1.25" nosepiece is threaded for filters. IMPORTANT: The screw hole on the 1.25" eyepiece holder requires tapping and re-threading, therefore the discounted price: £25 SOLD Gerd Neumann Jr. Ronchi Okular 10L/mm. This is useful for checking whether the optics have turned edge: £20 SOLD Set of 1.25" Orion coloured filters (made in Japan): #38A (blue), #58 (green), #23A (red): £30 SOLD Price includes 1st class Royal Mail signed-for. Payment via bank transfer or PayPal as friends.
This has been my project since the start of this season and now I think I´ll just leave it... for now 😉
I started last season (with a longer FL) but didn´t like how my Baader O3 filter matched the Astrodon Ha filter, so now I had to get a 3nm O3 as well.
This is a total of:
60*5 minutes of 3nm Ha
114*5 minutes of 3nm O3.
Shot with a ZWO ASI1600MM-Cool and a Canon 300/4L IS tele lens. The lens suffers from bad star shapes in the corners but I managed to get it decent anyway. Didn´t want to stop it down from f/4 either.
Combined as a semi-RGB (or what to call it) from R=Ha, G=70%O3+30%Ha, B=O3. Processed it as LRGB using a combined Lum from 60% Ha L and 40% O3 L.
I am really happy that I finally feel satisfied with a target! Usually I just get restless and move on when half of the data is collected.
Hope you like it!
