I am very surprised at people not wanting to upgrade to Windows 10, it is beautifully stable, reliable and has never crashed any of our business machines, going back in time to Windows 7 is a derogatory step for upgrades and support.

Would this not be a good solution: 

M48 Camera Adapter 

If yes then we already stock them, in Sony fit too ?

Steve 

Thanks Steve, unfortunately the Sony A7R3 is an e-mount

Hi Steve, first place I looked at was FLO, but I imagine you have to stock where the demand is and the Sony's are now taking quite a strong hold after claiming to have resolved the star eating firmware. Selling all my Leica and Nikon equipment was a very big switch, but the Sony results sold me for widefield etc.

Hi I have on order the following to attach it to the A7R3 -

 - M48 Female to T2 Male Adaptor 6mm Optical Length

 - T-Mount for Sony Alpha

 

WO are working on production of a single adapter so may get this if the setup i am getting is any way awkward.

"what back focus are you going to work to when the red cat arrives?" The redcat has about 4" of travel with the helical focus mechanism which is part of the petzval design so there is no issue, with focusing.

So is the Red cat a T2 (42mm) fitment?

If you have a 48mm T adapter with the e-mount can I ask where you got that from?

I currently use A Sony 100-400 GM (1.3kg) on a A7R3...

Slightly off topic, but I have just bought the same camera and was interested in the red cat, where did you manage to find a 48mm T adapter and what back focus are you going to work to when the red cat arrives?

Carbon will cool down far quicker than steel and won't expand as much.

Why is is than most if not all of the high end OTA's are either truss designed or carbon or both, but very rarely steel if ever.

As previously a manufacturer of high quality extreme condition waterproof items Steve I have to say lets agree to disagree, my knowledge was gained from working within the industry and taped seams were definitely not cheaper as they were far more labour intensive.

Grant maybe using my old cover, but it does not explain the 1/2 pint of water that I had to empty out of my mount whilst in use.

I'll leave it at that as we have two totally different opinions.

I know what you are saying Steve but Telegizmo have no excuse for not taping their seams, every single outdoor product clothing or camping company worth their salt should tape them, I've heard so many claims over the years about threads expanding etc. and special waxes and sealants, you can't seal perfectly something that doesn't weld or chemical seal as an overlay of the seam.

When a needle enters material this thick it gets hot, very hot, I have had a needle go right through the nail, and bone and come out the other side and there was no blood, lot of pain and swearing and jumping around on one foot but no blood.

When heat it applied to plastic materials it shrinks away and makes a bigger hole thus relying on the thread that is smaller than the hole to expand and seal, in my professional past experience it doesn't, it needs to be taped.

If there was a magical thread that could chemically bond then why don't all the outdoor clothing manufacturers do that, I suggest that you go into any reputable outdoor clothing company and see if you can find any waterproof garments that aren't taped.

I have over £10K's of equipment sitting out on my pier and I certainly am not going to take another risk with just the telegizmo, thus the reason why I use two covers.

This i no reflection on any company that sells Telegizmo, it is just a matter of fact, seams need to be welded or taped.

Hi John, you’ve tagged me into the conversation. Can I help? 

Steve 

Hi Steve, Sorry was just showing that you were helpful in getting things sorted for me even though you were surprised that the telegizmo leaked..

This is helpful, John. So the range you are happy with is the 365 telegizmo?

Hi Jeremy,

I used to design and manufacture waterproof equipment for the angling trade and my father was a tailor and he taught me to sew, so I have a particularly keen eye on working with waterproof materials.

In my opinion, the material used in the Telegizmo 365 is superb, I particularity like the aluminium reflective lining that should help keep things cool, what I really don't like is the fact that they never taped the seams, they have just sewn them together!?.

The material has a superb hydrostatic head and the technical specs appear to be excellent, it maybe that the material will not accept taping, but claiming it to be 100% waterproof can only relate to the material as the seams which to my mind are every bit as important if not more so lets it down.

I purchased originally a smaller one in July last year Like this and by the beginning of September it was leaking like a sieve, fortunately after contacting Telegizmo in the US they suggested my contacting FLO for a replacement, which they happily did.

When I upgraded my mount and because of the weight of my 10" and camera's I decided to invest in the larger Teelgizmo specifically this one so that over multiple nights I could safely leave my kit out without fear of any water penetration, it is a massive cover, however when I looked inside in bright day light I could still see light at the stitch holes, now some manufacturers argue that the thread they use expands in the wet to close up the seams, sadly in my experience that never proves to be the case or indeed safe practice, as you are relying on water in the first place!!!

Testing of this cover in the ice cold Colorado winters and heavy snow is not going to show up how waterproof it is, you need torrential down pours to prove that and the rain we have in the UK does just that.

My way to resolve the issue was to buy a large water proof and taped cover from ENS such as This one the material is breathable and more importantly is waterproof, so with the combination of the two covers I hope that I have done my utmost to safely protect my equipment.

Sorry for the long winded reply, and just to clarify, FLO collected and replaced the originally cover very speedily, I just feel that the cover is not 100% waterproof as the manufacturers claim.

Yes, I agree. I bought one of the cheaper Telegizmo covers and was amazed that the seams were not taped. There are very evident holes along some of stitch lines - a few of them being big enough to let narrow shafts of sunlight through, so I doubt would be water-tight.

Very disappointed and would not recommend them.

Yep Kev, Steve @FLO was surprised that it leaked when I sent it back, suggesting that mine was the first, but with half a pint of water that I had to empty out of my mounts guts I wasn't best pleased with Telegizmo.

I couldn't trust it without a taped and seamed cover over the top, I ordered the largest one they make so hopefully at £165 it will last unlike its predecessor which Steve replaced for me.

Ahmed, I use a Telegizmo 365 and one of the ENS waterproof breathable covers, having been let down with a Telegizmo 365 before I didn't want to risk £10K+ of equipment sitting under a cover that is not taped.

I find it absolutely incredible that telegizmo promote their products without them being heat taped at the seams, I've been involved over many years with the design of waterproof equipment and nobody in their right mind would consider something waterproof without taped seams, I use one because of the material they use and then cover it with the ENS which looks better in the garden and does have taped seams.

Can you not use a bicycle chain/lock to wrap around the mount and attach to the pier. I guess I am making the assumption that nobody is going to arrive at your property armed with the correct spanner to remove the mount (security bolts could be used).

I live in a rural village, the 120 weighs 23 Kgs and another 30kgs for the CW Bar and weights, if they are strong enough to lift it then they are welcome to it, I work from home so it is never left unattended.

I leave my mount out all the time secured now with security torx bolts and I use a large Telegizmo 365 cover over not just the mount but also my OTA if planning on a lengthy target, I then cover with one of ENS's waterproof breathable covers for extra protection https://ensoptical.co.uk/index.php?_route_=telescope-covers/tempest-large-long-cover

It might seem like over £250 worth of protection, but it save so much time.

Just wondered if there would be support for Sony Cameras?

Can I jump on this band wagon and get a copy of the plans please?  Looking at getting a quote from a local fabricator to know one up

No Probs Just PM'd you the drawings

When I had mine built there was many discussions about having the pier level and that no flexure could occur with needing levelling nuts and bolts, I think it was referred to as a rats nest, so I had the concrete poured level 75cm x 75cm and I built a level frame work and ask the builder to make sure that he levelled the concrete to the wooden frame, a week later its solid and the pier bolted down. any levelling is corrected by your polar alignment.

Not a pain at all, glad to share.

John, I appreciate he's you're friend and you're sticking up for him, but i'm entitled to express my views as i see them from my side of the fence as it were. I wasn't personally attacking peter as i'm sure he's a great guy, I'm just saying that from my point of view, if you're going to repond to someone then i'd rahter them just to say that they are busy and they'll get back to the person for a porper discussion at a later date, or just not repond at all until they are ready.

At the end of the Day i was simply asking for information on his Current N-Series of scopes, He didn't answer my questions - so i simply rule out his scopes as a possible option. There is no ill feeling towards peter or his company or the scopes he makes as i dont know enough about them.

 

No Probs, I'm not going to comment or post any more on this thread, for the reasons I posted above.

JKulins, thanks my friend, i would be most happy to receive a copy; can i just point out to all assembled here, i can not get any one due to cost to have any metal tubing welded etc, the only pro to this is that, i would use a metal tube of 8/10" external dimension and, approximately 5/6 ft in length so as to give a very good depth when sinking it into the excavation ready for concreting work, hope this gives a good reason as to why i won't be envisioning welding work in total, all screws and bolts and the like!.

 

                                                                                         Grateful thanks and regards to all,         Tom.

Just PM'd them to you Tom,

From what I understand Peter said that he could only offer the specific hand built OTA's on his website at the moment as he is developing a high end quality Newtonian that he is not ready to launch yet. He actually read his reply to me which was along the lines that his quality Newtownians were in development and not ready for market, not that he can't , only that it is in development.

So he gave you a straight answer from what I understand.

As for lacklustre response, he has been away for virtually 4 solid weeks with very little sleep working through the night setting up an army of new scopes at E-Eye in Spain, he hasn't seen his wife or son for ages, give him a bit of a break.

If it helps I can give you the plans for my pier that a mate designed for me: -

Waiting to see what 656imaging can offer, but no response as yet.

As I mentioned Peter has been in Spain all last week and only flew back yesterday, he stopped in at my place on the way home this morning and mentioned that once he has seen his family and unpacked then he will reply accordingly.

Sorry missed your comment about home not having any photos. I understand  that the scopes are custom, but surely he must have photos of previously built N series scopes, or is it a case that he has never yet built a N series scope ?

That said, I've not heard of this guy before , so not going to risk 2k of my money on an scope builder I've never heard of before.

Rich.

No Probs Rich,

Peter is world renown for his skills in Astrophotography, Orion use him when they need a scope troubleshooting or setting up, I've just got off the phone to him as he is currently in Spain setting a complete armoury at Remote Scopes at E-Eye, this is his 3rd trip in as many weeks setting up I think it was 9 systems, here's a pic he sent me the other day from Spain: -

I wrote Peters Powerpoint presentation for the PAS show and here was just a few of the magazines he was published in: -

Peter has been plagued with requests for Newtownians, so he has launched a range based on his skill set and knowledge, I've mentioned to him about photos but between travelling to Spain regularly and with the launch of his business he's just plain run out of time.

I hope that explains a little, he's a bit of a specialist, oh and a good mate as well ?

Just had a look at those scopes and they look exactly like a CT10, the mirror configuration is the same and I'm pretty sure that the price is identical to the CT10.

As my grandfather used to say : if it looks like a duck and quacks like a duck, then it's a duck.

I assume you didn't read my post then?...
