... The only thing to be careful of with this method is the risk of dropping something down the tube!

Actually dropping something down the tube is likely not as bad as all that, unless the object is big or the tube is pointed very high. Obviously it's not something you want to do. Whenever I've dropped stuff down the tube, it's hit the tube-side and slid down to rest in the gap around the primary. It's been inconvenient, fishing it out again, or pointing the scope "down" to let it slide back out, but an allen key or some such is unlikely to hit the primary.

Also, I have a SW 200p solid-tube newt. I've had to bolster it with an air-conditioning ring-clip near the focuser to stiffen it up, because beforehand simply changing altitude would throw the collimation off.

I suspect other manufactures like LZOS and Stellarvue with steel lens cells can keep the same performance but with larger apertures, in the winter I'll find out.  

I’ve found that my LZOS 105 takes a fair while to cool down such that the extra-focal spikes disappear. Obviously dependent on temp difference but 40 minutes at least is a rough guess.

I just had a quick look (2348) before bed as the clouds have cleared. Through my 15x56 bins, I had it as very very slightly dimmer than HD220057, which is mag 6.94. So a smidge over or perhaps just at 7.0 .

I ‘ve just purchased a Tele-Vue 85 and a TV 55mm plossl 2”, using the supplied 2” everbrite diagonal I don’t have enough back focus! I had to pull the eyepiece back another 15mm ish to get it to focus….terrestrially! My TV  40and 32 plossls are 1.25” and focus is fine, what am I missing? Apart from a few grey cells!

I never used the 55 I think so was unable to warn you of the problem, hopefully a barrel extender sorts it out!

Interesting, 6 mirror clips. My (rather older) 300p cell only has 3 clips.

Broken cloud here more cloud than clear and totally covered in Cass direction

I had it at an estimated 5.6 last night, 2322. A smudge dimmer IMO than HR8894

Was this naked eye Magnus ?

 

Haha no. I’m in mag 19 skies and that direction for me is very bright so naked eye no chance, I was only just able yo make out the W of Cass naked eye. I had my Zeiss 15x56 binoculars.

After being shamed by @PeterW for not bothering to venture beyond my garden (living room actually) to skirt obstructions, I went out to a local alley with a view N and with @Stu’s help found it fairly quickly. Pretty pleased, and maybe a faint hint of M52 in averted knowing exactly where it was but not sure.

I have an Oklop skymax-180 bag, superb. IIRC it has hand-carry handle straps, but also satchel-straps to carry it rucksack-wise. Really really good.

I was changing the focusser on a reflector tube and might have put a wee dent in it trying to get the mirror cell back in….. slightly sitting on it. not that anyone noticed.

Was it your scope? 🤣

Oops sorry  I meant your Z66. Perhaps mag is something to do with it for me, my Leica zoom goes only to 48x. I might try simply hand-holding a higher-power eyepiece in the larger “hole” to see if that works…

Anyway, Izar beckons in a proper scope and thanks for the reminder

Glad to be reminded of Izar, I’ll have a go too next clear night.

Have you tried for Polaris B with your Z61? I have a Leica 62mm spotting scope which I sometimes use as a “super finder” and have just about managed to detect Polaris B through it only once out of several tries. A couple of those times were with the scope side by side with my LZOS 105, through which Polaris B is always easy.

Cheers, Magnus

I just bumped into Alice and Bob. They’re both confused, angry and sulking

Hi Magnus & thanks for your reply & photo! 

When I saw your post, I thought yes!!! that's excatly what I need - until I read the weight capacity of the mount....... It's only rated for 44lbs max, my set up would be at least 50lbs plus. Your set up looks to be at least 22lbs over the max rated payload........

The FLO website for the mount says "Payload Capacity: 18kg for imaging and 25kg for visual". i.e. 40 pounds and 55 pounds. I believe the Orion Atlas is the same so it seems odd they'd quote different numbers. Anyway, at 66 pounds (for visual) and admittedly with a much sturdier tripod than the supplied one (mine's a Berlebach Planet) my set up has worked perfectly like that for several years.

M

I have a Skywatcher AZ-EQ6, which quite happily handles (for visual) my Skywatcher steel-tube 12" newt plus finders and Paracorr2 plus heavy eyepieces. All told that's getting on for 30kg (66lbs). I believe in the US it's marketed as Orion Atlas.

Cheers, Magnus

It’ll make a very interesting comparison with the panoptic 35. The Nagler has smaller focal length hence greater magnification, but wider FoV. I’ll do the comparison and report back in due course.

Sadly thereafter the Pan 35 will likely be released to help fund this.

… Just amazing what can be seen with the right telescope in the right location in the right hands. …

I guess two out of three ain’t bad 😉

A monster arrived in the post this morning:

… and by way of comparison with a Pan 24:

That's impressive! Were those taken under urban or rural skies? Either way, I've got to try NV.

How much money do you have? 🤣🤣

I sold exactly one of these for £150 a year or so ago. Good mount actually.

A big dob is highly recommended for deep sky exploring- eagerly waiting to see what you get Magnus!

I’ll be getting Robert’s 500p when his wife sticks it on eBay 😉

I bet you’re glad you went straight in at the deep end all those months/coupleofyears ago and arrived home with a 20”. We certainly are! I’m in the market for a similar sized dob and you are providing lots of inspiration not to mention obs lists!

Thanks

These are my two solar scopes on my new to me TS AZ5.

What? TWO sets of binos?

Not sure what to make of that. BinobinoViewers? And that’s quite apart from any considerations of how to pronounce it: binno-viewers or bye-no-viewers.

Seriously though, from one Skytee2 addict, very nice-looking set-up.

Nice read thank you. Thanks for pointing me to NGC 6811, I’ll take a look for the “hole” myself too.

BTW you might want to change the date in your title to April 🙂

Cheers, Magnus
