  1. "For DSOs go with the largest aperture you can manage" - is the mantra given for a reason: 8" for me got me to view all the Messier objects at a darkish site however when I moved up to 12" the difference is vast in what I could actually see and giving to actually wow moments in visual observing. Training the eye and observing technique is also a big part of visual astronomy as well. 10" would serve you very well - the difference in light gathering from 8" is pretty large so you will benefit greatly. Don't worry that much about coma - when you build your eyepiece collection, add eyepieces
  2. I bought an SCT as my first scope as its compact size and weight was good for lugging to my darkish site on foot without sacrificing too much aperture. The EQ5 mount held it well. I did all of the Messier list with my C8 and a good start on the Herschel 400. The SCT design though is a real pain for any amount of dew and freezing conditions rendering them virtually useless without a shield and a heater. Cooling off the 8" size took an age although I didn't find that bothersome for DSOs it did give good planetary views when stable - stars though were never really brilliantly sharp especially
  3. Uff... it's been so long since my last proper session (almost a year). My 3 year old daughter is finally sleeping through the night so I can get back my time! It was incredibly clear however brutally cold so setup my 120ST for a "quick" session at 11:30ish - I finished at just before 2am my feet had turned into blocks of ice... Most observations made with the 17.3 Delos. Started out with Leo - a little low down at the start but M65 and M66 easily visible - Couldn't get NGC3628 though it may just have been a little too low down for this... Across then to the M105 group then M95 and M
  4. Ah, that's a shame..... Get a bigger car???? I used to walk with gear from my apartment about 15 mins walk to an allotment where at least I kept my mount in a shed. I can relate to the need to keep it lightweight though! TBH, the mount is the most problematic to find something sturdy enough (especially for planetary obsevation) that you can physically walk with the any length of time so perhaps stick with using the car. If the tripod at least goes in without having to lay down the seats you may have more options?
  5. If you're going with a scope in the car and setting up in the car park how much effort is it really to take a decent size aperture scope? For planetary you can do that from your garden as street lights won't generally affect your view and for DSOs starting out on the Messier list for example you want pretty reasonable light gathering capability even without light pollution.
  6. I've posted this item before quite some time ago... Now attempting to re-sell as the Paracorr creates too much of a balance issue with my Dob so I'll never use it... I bought this used on Ebay (sigh) and has not had much use by myself but I have thoroughly checked it over and tested it with multiple eyepieces. The bad stuff: 1. When I originally bought it - It had a minor amount of fungus just off centre of one of the lens however I can't tell which one. I have had it stored in a very dry environment since I've had it and cleaned it to the best of my ability with Baader Wonder
  7. Only used a handful of times - in mint condition but no box. Will be exceptionally well packaged though! £215 including Royal Mail delivery
  8. For galaxies my most used with the same scope is 10mm and 14mm (depending on the object and sky transparency). For PNs I will always use the 7mm and alot of time my 5mm. If you were only going to get one eyepiece at this time I would choose the 10mm. If you want narrow field then for budget the Baader BCO 10mm would be difficult to beat with its excellent performance for these type of objects.
  9. The field edition of Interstellarum deep sky guide to go with the atlas.
  10. Oops! Sorry Doug!!! Not sure where I got the name Neil from.... Brain not engaging this morning with the late night!
  11. Hi Mark. I'm not sure that it's available for Android but worth checking.... Good to hear you got out as well for a decent session! Hopefully I'll have another opportunity soon to see if I can catch the Rosette with the bins or the 120ST from the park as it's much better situated than my house for viewing. Ursa Minor is a great judge for NELM it has several stars from mag 5 to 6. 19 Umi is mag 5.5 I forgot to mention... I need to see if I can get 24 Umi (mag 5.8) although its proximity to the much brighter 4.3 mag Delta Umi (Yildan) may make it a tougher target. I think the neb
  12. OK... It cleared (sort of). We've had rain with high wind pretty much solid for the last 2 or 3 days and everything was deeply wet. As I popped my head out at 10 for a gander I could see the stars (sort of) - there was soup and lots of it as the obviously very humidity level was just killing it. I checked again at 11pm , 12pm... and 1am. It had gotten much better. I was pretty much done from the day's activities however I didn't want to completely waste a night... So binoculars it was taking them to the nearby part away from any local light sources and took my iPhone for taking the SQM measure
  13. Nice report Neil! It's been quite some time since I last observed M78. I actually tried a couple of weeks ago with my 120ST but the transparency was no good at all. For me, the optimal exit pupil for obtaining the maximum detail from a DSO is somewhere between 1.5mm and 2.5mm depending on the transparency of the sky. Some objects will happily take even higher powers - M42 and some planetary nebulae for example will happily take an exit pupil of 1mm and show even more detail.
  14. Wow, that's pretty productive for 2 hours! Sounds like you had a nice transparent sky to work with. Thanks for the great report.
  15. Well done! That's a really good list and cross section of objects for a session and good to see that 5" reflector performs nicely. Goes to show that a transparent and dark enough sky works wonders. Must have been good to see NGC 3628 which very easily gets washed out as it's so diffuse. Many thanks for the report!
  16. As the storm passed it cleared although there was a thick haze early evening so didn’t even think about getting a scope out. After a nap and waking up at 1am the sky certainly looked considerably better and dark although looks can be deceiving... So I popped out the AZ4 and the 120ST and gave it a go. Well I was glad I didn’t bother getting the dob out! It was wet, the air was wet and soon my scope was sopping with the humidity. I could tell the transparency wasn’t good either... However, I managed to get a few in though to at least call it productive of sorts. I started with th
  17. Well done Doug for your persistence!!! M97 is certainly one of those objects that can be made "visible" with OIII filter if it's not visible without one. I think though that if you cannot see M97 without a filter you've got no chance at M108 which has given me a kicking on several occasions before with the sky has not been sufficiently dark or the transparency is not high enough.
  18. A great selection of objects and lots of doubles! I don't know what dark site (I don't have car to lug astro stuff anyway) but looking over the valley from the top of Belper there looks to be some really great locations itself towards Shottle. What's the NELM for the dark site?
  19. If it's clear I'll be out!!! Besides, this looks like the last night for some time if the weather forecast is to be believed so I can have a rest tomorrow night!
  20. Nice one Geoff! Good list of galaxies there. The C8 is a great scope for galaxies.
  21. Aargh. That’s annoying. I use Sky Safari and found it to be very accurate generally. I wonder how that star didn’t get included in the catalog.
  22. Thanks! I was using the 12” dob.
