On my 8se I use a TalentCell Rechargeable 36W 12V/6000mAh 5V/12000mAh DC Output Lithium Ion Battery Pack. I have it attached to the mount via an old Garmin gps bag, and it last for ages. Found here: https://www.amazon.com/TalentCell-Rechargeable-12000mAh-Multi-led-indicator/dp/B00ME3ZH7C/ref=sr_1_2?dchild=1&keywords=TalentCell+Rechargeable+36W+12V%2F6000mAh+5V%2F12000mAh+DC+Output+Lithium+Ion+Battery+Pack&qid=1603995224&sr=8-2

Why do some observers not "get on" with binoviewers
Mick H replied to Paz's topic in Discussions - Eyepieces
I started in astronomy using binoculars. When I got my scope after one year I brought my William Optics Binoviewers and have used them ever since, I really like them but.......... I have to sit down when using them for some reason. -
Strange goings on with the sun this morning
Mick H replied to AstroNebulee's topic in Imaging - Solar
Lovely images Lee, I think you have discovered that our Sun is infact a Double Star, which will now be called the LeeHore7 Double. 😉...........or Clean your windows. -
Hi Hugh, I saw M27 visually last week with my WO binoviewers for the first time and thought wow. But that is a lovely image well done.

Maybe you can make a spacer to put under your finder scope to help tighten a bit. For future reference I had a red dot finder on my NexStar 8se which I ditched for a Terad finder, but this might be to big for your scope. So maybe consider a Rigel Quick Finder found here: https://www.firstlightoptics.com/finders/rigel-quikfinder-compact-reflex-sight.html

Beautiful photo Martyn, well done.

Hi Neno, I would say for what you are trying to achieve you don't need StarSense. Polar aligned with wedge plus sky aligned via CPWI, plus you are going hibernate the mount. I have StarSense and love it, press auto align and away it goes and never fails from my position, plus it is great when you go to different locations.

👍 Hi Lee, I have the same it arrived last week. But sadly it has been cloudy with lots of rain, only tried the all sky camera so far. Looking forward to trying it on Moon/Planets soon. 🙏

Hi Siouxsie, glad you are happy with your Celestron's Lthium Power Tanks. I use TalentCent Rechargeable 12000mAh Lithium battery pack seen here: https://www.amazon.co.uk/gp/product/B0713T4XT9/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 I placed it in a Garmin gps bag and hung around the mount, so no more cord wrap. 🥳 Very pleased with it, and has lasted three sessions without a recharge.

Bortle 4 here in Wroxham/Norfolk. Even better when the pub across the river turns their lights off at around 11.30pm, but a great big grey shed sort of East helps.

Visual filter recommendations
Mick H replied to Andy38416's topic in Getting Started Equipment Help and Advice
Agree John, I used it for M27 and it was lovely, pulled it right out. Can't wait for M42 -
Visual filter recommendations
Mick H replied to Andy38416's topic in Getting Started Equipment Help and Advice
Hi Andy, I also have Nexstar 8se. For future reference you maybe should be looking at some Messier objects with your scope. I have just acquired a Astronomik UHC filter, and last Saturday manage to see M27 Dumbbell Nebula which stood right out. Also M13 Globular Cluster and the Double Cluster, I'm starting to go through the list. -
A 9-feet print of a DSO (M16) and a happy mum
Mick H replied to B4silio's topic in Imaging - Deep Sky
Grüezi, das ist wunderbar. Sorry I could not resist, I lived in Baden Aargau for a few years. Thanks for sharing. -
Hi Bloom, lovely pics well done. Looking forward to you Mars pics If I can achieve something like that with my new ASI camera i would be very happy.

Binoviewer & dob combo question
Mick H replied to BS269's topic in Discussions - Scopes / Whole setups
BS269, Just trying to help and found another bit of info: There are two types of vignetting to consider -- vignetting at the center of the field, and vignetting at the edge of the field. For planetary work you only care about the field center, but for other stuff you care about both. Vignetting at the field center does not depend on the eyepiece focal length / field size. It only depends on the scopes F ratio and the size of the prisms. Most of the binoviewers add about 5 inches to the optical path. So a unit with say one inch prisms should be OK with focal ratio 5" / 1" = F5 or slower. For one of the binoviewers with small prisms its 5" / (1/2") = F10 or slower. Vignetting at the field edge is more complex. It depends on the scope light cone, the size of prisms in the binoviewer, and the size of the eyepiece field stop. If the binoviewer is one of the microscope derived units with 12mm prisms, and you use an eyepiece with a 27mm field stop, the field edges are going to be completely vignetted (dark) no matter what the scopes focal ratio is. Fast scopes will probably have some vignetting at the field edge, even with large prisms -- maybe 50% light loss at the edge -- detectable but not terrible. -
Binoviewer & dob combo question
Mick H replied to BS269's topic in Discussions - Scopes / Whole setups
Hi, I cannot help with your question but this might help: https://agenaastro.com/articles/guides/eyepieces-binoviewers/choosing-astronomy-eyepieces-for-binoviewers.html I have the WO binoviewer, but wished I had gone for the Baader MaxBright's to pair up with the Baader T2 diagonal which would make shortening the light path easier like in the pic below. -
Manual vs Goto Mount & Scope
Mick H replied to MathewRimmington's topic in Getting Started General Help and Advice
I love my NexStar 8se goto. I added StarSense Auto align once I have added my location it stays in the mount, and can be setup in five minutes. I bring scope out plug in set date/time and away it goes, I don't like staring at laptop/iPhone so don't use wifi anymore as I have learnt so much about the sky. So for me using hand control, I Sky tour or tap in Messier objects and just sit there studying those for quite some time. If portability is what your after then as banjaxed stated a 127 Mak would be ideal. -
One of my favourite Aunties sent me a ZWO Camera (no not the Devonshire Abbey one the other one) today along with a Astronomik UHC filter.

Thanks Mike, I look into that reducer/corrector, I love seeing the whole of the Moon.
