Bit of a backround: I've been a keen stargazer when in my teenage years, then couldn't pursuit my passion, but recently, in my forties, it hit me again, as I moved and life is good (South facing large garden, obstructed only from the North by our house, but then I just move the scope further and viola!). Started with 90mm refractor, but was always thinking of reflector.
Long story short, I've got my SkyWatcher Star Discovery 150P GOTO a week ago. Bought it second hand, very good condition, and good mirror. Have got two nights stargazing, cought cold and I AM LOVING IT.
Now I would like to get me a nice wide angle ep for DSO spotting.
The scope is 150mm / 750mm f5. I've done some reading obviously, and Explore Scientific 82 degree series have all good reviews and fit within my budget. I can afford only one, and apparently the best for DSOs is the one that gives 2mm exit pupil. Now, for my scope that would be 10mm piece, and that is not within ES 82 degree range, so it's down to 11mm (2.2mm exit pupil) or 8.8mm (1.76mm exit pupil).
My question is: which one would be better for my rediscovered passion? I'm gonna be using that ep for faint mostly.
Thanks to everyone in advance for any kind advise.
The Wizard Nebula
An emission nebula 7,200 light years away and my first proper project of the new imaging year.
Really happy with it as I’ve had a steep learning curve with new kit so really pleased to see this image come together. It’s also the first time I’ve imaged it.
72x180s subs collected over 2 nights 24/25th August in my Bortle 7 back garden, Whitley Bay, England
Calibrated with darks, flats and dark flats in DSS and processed in SiriL and Photoshop.
Lacerta 72mm f/6 APO
ZWO ASI1600MC Pro at -15C gain 200
ZWO 60mm guide scope
ZWO ASI120MM-S guide camera
Altair Astro 2” Tri Band OSC Filter
Data collected in APT and guided with PHD2
Hi everyone - it's been a while!
This has been on my hard drive for almost 2 months and I finally got round to processing it...it was quite optimistic of me to try and image this from my Bortle 7-8 back garden, but I gave it a go! While the nebula itself is clear to see, all those gorgeous dust clouds surrounding it were extremely hard for me to capture from my location without a lot more integration time. I think I'll head to dark skies to capture this one next time, along with some more focal length!
LRGB shot with ASI1600MM Pro and WO Z73. 2.9 hours of integration time.
Full details here.
Thanks for looking!
This is a recent edit of data I collected back in January. Image is taken with a Canon 450Da and Canon EF L 70-200mm f/2.8 lens sitting on a Sky-Watcher Star Adventurer. It’s quite a large crop from a 200mm frame. 25 x 3 min guided subs. Stacked in SiriL and processed in Photoshop. Image taken in Northumberland under Bortle 3 skies.
