Watching with interest as to what comes out. The UFO/UAP phenomena has interested me since early teens, and still does so now many years later. Governments around the world know much more than they are letting on. Quite a few theories on what they are and where they are from etc (from alien visitations at one end of the scale, to earth energies that creates the UAP’s in the mind of any observer), but there is something to the phenomena as much as it gets ridiculed and scorned at in main stream media, so I keep a very open mind on the subject.

Nice shot. Very busy up there! Might get my scope out to have a looksie too! 👍🏻

That's some really good bookshelves! Here's mine, but my favourite book won't fit in the shelf, that being Antonin Becvar's Atlas of the Heavens.
Of the books on the shelves Burhnam's Celestial Handbooks are my favourite, I also found a copy of the 16th edition of the Norton Star Atlas to go with them.
Yes, Becvar’s AOTH is a beautiful book. Found my copy on ebay over a year ago in very good condition still, but minus the key part which was missing as it is a separate leaf. Managed to find an image of one online and printed a copy of it.

I guess it's just what happens when you move the goal posts. A bit like 10 UMa being in the constellation Lynx and not Ursa Major, the sky is full of indiscrepancies.
Yep, exactly. Anachronisms abound in a few places in the heavens.

I’m guessing that people making the later more modern charts are referencing this double from much earlier charts. So is this a case of them just copy and pasting here and not noticing this confusion with its designation here? 🤔

With reference to the star you have red circled and is designated Struve 2021 / 49. On my S&T sky atlas it’s just marked as 49 Ser. Therefore it’s definitely not 49 Herculis! On your chart it’s a bit confusing to have 2 stars with the same Flamsteed number in the same constellation!Yep, confusing it is. Where are the chart police when you need ‘em?

What edition CDSA do you have? Edition 1 is very different from edition 2. Edition 1 definitely had mistakes. Edition 2 was not just an update but a complete rewrite, and much the better for that.Just checked my CDSA edition 2, chart 10. The star you have red circled and is designated Struve 2021 / 49 is just designated Struve 2021 in edition 2. It’s close to the Serpens Caput border. Perhaps precession has shifted it from Serpens Caput into Hercules. Also on your chart the 49 designation must be a mistake. 49 is a Flamsteed number and is way too high a number for the west side of Hercules.
Also in my edition 49 Herculis agrees with the other star you have red circled and is designated 49.
BTW, cannot recall if precession has shifted constellation borders east or west. Anyone remember?
The above is astronomy when it’s cloudy😊
It’s the second edition. It also lists it a a showpiece double in the list for Hercules in the lists after the charts. Definitely confusing for sure.

There is a reference to STF 2021 on CN https://www.cloudynights.com/topic/595742-49-serp-that-actually-in-hercules-stf-2021/
Yeah, confusing to call it 49 Serpentis still when not in that constellation no more. Astronomy certainly has some odd things with it!

Not all the books I have are shown here as there are approx another 20 to 30 spread over all the other book cases, but the biggest majority shown here mostly. The old copy Norton’s was the first star atlas I owned, followed not long after by the massive New Concise Atlas of the Universe back in the early 80’s. Last image shows the 2 books autographed by Patrick Moore and one by David A.Hardy which if I remember rightly was possibly the first book he published, but could be wrong on that!

My astro collection is not located in just one bookcase, but spread over 7 of them around the house, downstairs and upstairs. I have books starting from the early 80’s up until now. Although I do own an old star atlas I got off ebay just over a year ago that was published in the 60’s, and based on an earlier atlas published earlier last century. Got 2 books signed by Patrick Moore, and one signed by Davis A . Hardy from a competition from an astronomy magazine I won from the mid 80’s. Try and get photos of them later on.

After doing a brief session on Thursday evening with the only thing worth looking at been double stars due to the light nights, on the Friday evening I sat down to chart some interesting doubles to look at for next time. I was looking at doubles in Hercules with it been in a good position for me to observe with the street lamps near me. So looking in the Cambridge Double Star Atlas one of the first ones I jotted down was listed as Struve 2021, a 7.4/7.5 magnitude double with a separation of 4.1 seconds of arc. My list didn’t grow much longer as I was too tired to only note one other double to check out been Struve 2052.
So this afternoon I decided to check out and make a list in Skysafari for my Hercules doubles list taking shape to look at the next time I get my 102mm ED f11 ‘frac out under the skies. Looking at CDSA again at Struve 2021 it was also listed as 49 with what I assumed to mean 49 Herculis. Typing this in as a search on Skysafari it listed 49 Herculis as a 6.5 mag variable star, not a double, and not in the same location in Hercules either but further to the east. Typing in Struve 2021 in Skysafari did bring up the correct double I wanted, but was not listed as under 49 Herculis. Thinking that CDSA has made an error in listings it as 49 Herculis I checked in Sissy Hass’ book on double stars, where it is listed under Hercules, but listed as 49 Serpentis! Confused, I checked Burnham’s but it was listed only under Struve 2021. Finally checking also in my Deep Sky Atlas it has it listed in the chart also as 49, so as can be seen in the image below there are two items listed in the Hercules chart as number 49. Digging deeper it seems that Struve 2021 prior to re-defining the constellation boundaries before 1930 did used to lie in Serpens where it was listed as 49 Serpentis. So today it seems that it still retains this number in some charts still, with Hass listing it as 49 Serpentis even when in the list of doubles under Hercules!

Hi, just a heads up if anyone is looking to get Skysafari Plus or Pro versions apps for either their Apple or Android devices then they are having a massive discount on both versions at the moment for fathers day upcoming. Grab a bargain whilst you can! 👍🏻

TBH with my Skywatcher Heq5 pro mount I only use the syncan app to establish connection to the mount with my ipad, then use Skysafari app to control it. I find It easier use Skysafari when using the mount than the synscan app to get targets.

Looks interesting. Look forward to seeing it when available. 👍🏻

Skyportal is a very slimmed down version of Skysafari which is made by the same people for Celestron. I have Skyportal but never use it. I do however use Skysafari Pro both for a guide when out at my scopes, or when I am connecting up via goto too with Skysafari Pro. Stellarium is very good too, but I tend to rarely use it and favour Skysafari which I have on both my iphone and ipad. It does come up on offer quite regularly so keep any eye out for it and you could nab it cheaper.

Don't forget to show us when you make it.
Sadly when the display arrived yesterday the seller from ebay has sent the version without the keys on, so waiting for a response back from them if they have they version they advertised with the keys. If not I’ll ask for a refund and source another one from elsewhere. I just ordered the Protostax case to from the US, so await that to arrive as well. Managed to get tracker to close down with pressing one of the keys on the black and white e ink display I have at least, so slowly moving forward.

Yep, mostly observe as much as I can without filters visually.

Well, was supposed to be nice and clear here this afternoon and tonight, but so far still pretty much wall to wall cloud otherwise I’d have a crack at it.

I fear with the rise of AI misinformation is going to get even worse, so looking for any certain truths are going to be very much harder.
