Indeed James, you are perfectly correct and I respect the fact that what one can afford is usually the ultimate answer. Credit can be useful for some - as long as they know they can repay over time, but in my case, part of my father's estate assisted me in doing what I wanted, extra to other astro-viewing and imaging than Solar.

My AStro-club had the SolarMax 60mm as well as a PST-HA & CAL-k scopes acquired through a grant from our "National Lottery Fund" and in the beginning it was down to me to sort-out the casing etc., so that these can safely be used for public outreach and schools..

I decided that I would sooner or later acquire my own Solar-gear and as one of our previous club-members had his own astro-supply business, I put it to him to get me the best-gear on the market at the time - which was Lunt...

He and another very-well known presenter/imager, even delivered them personally to me and also viewed the observatory - which had barely been completed as a building, but not kitted out...

The decisions of that supplier - has been proven to be perfect, as my gear has been trialled along-side of other makes and found to be superior.

Further work relating to mounting three-scopes on the original Vixen-mount was not suitable due to the weight, so the acquisition of the SkyWatcher ALT/EQ6 GT was decided upon and also has proved to be well worthwhile...

I do though, need to polish-up on the imaging-side, where with the two new ASI 178MM's only were able to see a few lights up to November'20 and after a revamp of all of the computer-system, screens and wiring mods...

I'm on the verge of starting to observe and image from the observatory (this week) as well as working on the ETX-125 etc., for necessary measurements for the new mini-observatory, so very busy and with lots of other things to do as well.

Just shows that retirement is not always an easy-life, rather too-busy to need to work away from home - in any case...

Cheers
Terry

Good luck Terry on clear skies. I am waiting on your images. Retired life? I haven't got there yet. I still have a few years.

Just to re-open an older topic of price-differences, Now Lunt are doing a 40mm SolarScope at less than a £1,000 and comparing the 300mm version at around £130,000, I wonder whether the x130 could ever achieve a x130 better image ??

Also if anything gets in between the objective and the BF, wow immediately-grilled !!

Any further thoughts are welcome - whilst our Sun is sleeping...?

Buy 130 of the 40mm scopes and cherry pick those with the best etalons and send the rest back :lol:

Well Mark, I did actually think on those lines albeit I thought of making Lunt an offer to buy 130 at a reduced price/discount (their ears suddenly pricked-up) and then make sufficient profit to buy the APM 152MM F/7.9 DOUBLET ED-APO @ £3.5K by selling the 40's for a a small profit each.

On the other-hand, £3.5K could easily be spent - without the need for buying. storage-space, advertising, selling, post and packing of the 130 units, so I'd opt for the half-sized version at £3.5K... :movie :bow2

Yes Rod, quite right too :o

It's got me finking now, so how could I get to keep a 152 on another mount in another observatory ready for immediate use and still keep the Tri-Scope Assembly up and running as is in the Main observatory, plus the (ready to be erected) Mini-observatory with the Orion ED80T on a Vixen mount .. :?:

Answer:- I don't need the 152mm Apo, cus I've already got the Meade 127mm Apo-Triplet in mint condition and hardly used, so back to square one... :)

Terry, a little off topic, but Solarmax 90 with doublestack is worth in Russia, in terms of pounds 9700.

If my pound to dollar translator is right that's 13.480.43 US Dollars. I guess they think that tube is gold plated!!

Meade has them for 5899.00. Lately they are often hard to find at dealers. The SolarMax III series is gradually replacing the SolarMax II series.

https://www.meade.com/telescopes/solar- ... ilter.html

The SMIII90 is a thousand bucks higher.

https://www.meade.com/solar/solar-scope ... ilter.html

If I bought one now at these prices I would probably go with a Lunt LS80MT. The double stacked Lunt LS80MT would cost me just under 6000 dollars.

I got my Coronado SolarMax II 90 on a closeout at Woodland Hills Telescope more than 2400 dollars off of the current Meade list price! That was a no brainer!

Thank you Ivan and James for those comments.

I must agree with James though, as, except for the "gold plated" part, where I would have thought "solid gold" would be more appropriate at that price.

Also the current Meade/Orion/SolarMax situation has to be uncertain at the moment as to supply/availability and service.

Agreeing though that the LS80 certainly does seem an appropriate acquisition for the lower-half of the costing for available SolarScopes from Lunt, whereas as for other manufacturers, I will not personally like to comment on as problems have shown themselves here via posts...

Cheers
Terry

I would love to see someone with a Lunt 300 here. The largest refractor I know of on SolarChat is Alessandro's 228mm.

They do not think, they are sure that their telescope is golden :) Solarax 3 with double stack and a 30mm filter unit costs even more 1,158,990 rubles, which is 11,342 pounds or 15,867 dollars.

I've seen the scope, no idea how well it performs.

Im still trying to get some time on a 230mm scope, ive also been pondering the 228mm cell from iStar.

Until then, the Esprit 150 is the biggest i have. :S

Thanks again James, Ivan, Simon and James again.

Ivan, I have just briefly read through the Meade-ru website details, where clearly there are differences between the original Meade details published by Meade in the U.S. and U.K. etc., so without going into any price-differences/rates of exchange and any import/export duties, which will constantly change anyway from when the literature was originally published - it does seem that total costs within Russia may be much more than elsewhere for the identical product.

Ultimately though, until we know what is to become of the SolarMax production-side of the original Meade (now Orion) infrastructure, it remains to be seen what availability and prices and service to customers - will be...

I personally would in any case stay with Lunt, who have provided me with excellent results and service, as I know others have received too.

And Simon, I would have thought that the 230mm scope would be well-sufficient for any Solar purposes and I have just received and "1st Lighted" Esprit 80mm for WL, which will be sufficient for my purposes, unless I want to use the long and heavy 127mm Apo-Triplet.

Best wishes
Terry

The amateur astronomer's path is regularly littered with "white elephants."
Greed for aperture often ignores all the other requirements over and above the initial purchase price.

It is a highly specialised instrument.
By default the instrument will use very long focal lengths.
This places heavy demands on seeing conditions, tracking and support.
For ideal thermal reasons it must be mounted fully exposed and still allow hi-res imaging in wind.

If you don't have better than average seeing conditions then why bother?
If you don't have clear horizons, over the full southern arc, E-W, free from buildings then why bother?
Birds of prey soar on the thermals over forests. So avoid forests.
Farmers harvest fields leading to miles of bare earth.
Farmers and neighbours often plant trees.
Avoid wildfire areas, those given to frequent cloud or violent storms.

So, in summary:

A raised, open platform, on a private island, or peninsular.
On the northern shores of a large, high altitude lake.
No mountains or dark rocks to your south.

Sound about right? ;)

Absolutely correct Chris, so primarily the seeing-conditions and average weather-conditions, will prove the 300's worth, which for S.E.England is likely to be around 100-times less than the current manufacturer's price.

In fact its' value is really in the talking about it, as an example that "Big is definitely NOT always better"...

Thanks Chris and everybody who has taken their time in reading and replying about this "Behemoth"

And James, I would sooner buy a light aircraft - even with all the overheads and operating costs...

Thanks Mark, James, Eric and Rod.

Eric, certainly would have been good to know what view though the behemoth would have been then..

Hi Rod, that's some observatory/look-out station in (India). :!:
Many Moons away from Derbyshire and certainly good for ship-spotting, but the trees as well as the hut on top have spoilt the effort for all-round astronomical observation - surely ?? :roll: :lol: :arrow: :movie

Best Wishes though

Hi Terry
Yep not good all round views but it is just a solar observatory. The India National Observatory have two of these Zeiss Coude telescopes setup solely for solar work, this being the best one setup on the edge of a steep mountain on the 30 foot tower to get the best seeing.

I would like to move my Zeiss for better seeing but in the UK nowhere is safe anymore, I moved to a small village to get good skies fifteen years ago and built the observatory for my Zeiss, since then I have been sounded by houses and LED street lights :(

Cheers Rod

Hi everyone.

I have an ARIES D-ERF from Valery for a C14:

Didn't have supporting seeing when I used it a few times. I hope to put it to the test in late Aug/Sep this year when the seeing gets better.

Hi Mark,

I started with a C8 fitted with a tri-band ARIES D-ERF. Lessons from using the C8 and subsequently C11 helped me gain confidence in using SCT for solar imaging.

This ERF is HA only. I had it for some time. I need to resolve tube current problems, get a nice focuser and a good HA blocking filter for it to get it working properly.

Thank you Rod for the update on the clearly well-made structure in India.
The height of the structure should certainly give some excellent views. :D

" I would like to move my Zeiss for better seeing but in the UK nowhere is safe anymore, I moved to a small village to get good skies fifteen years ago and built the observatory for my Zeiss, since then I have been sounded by houses and LED street lights :( " you have said :-

From a safe point of view, the need to alarm observatories and insure against theft, is likely becoming more of an issue in the U.K. and the unnecessary increase in both housing and light-pollution, is certainly encroaching on us being able to see the night skies compared to over 30-years ago, which at least doesn't affect Solar and Lunar views - where a clear line of site is available. :shock:

Unfortunately even now with the (so often) councils switching-off some street-lighting after around midnight, there appear to be many householders who are now using exterior-lighting, both badly-designed and very-badly angled causing unnecessary flood-light pollution. Only a little thought is required to stop those householders from imposing their pollution on others, but noise and other pollutions is something that will only get worse - unless sufficient legal-action can and will be taken against those issuers... :evil:

The downside of powerful LED lighting is a large cause of the problem, due to its' miniscule running costs, allowing all-night switch-on's... :oops:

Cheers
Terry

The downside of powerful LED lighting is a large cause of the problem, due to its' miniscule running costs, allowing all-night switch-on's... :oops:

Mirrors! :evil:

Arrange large mirrors to shine their light straight back at their windows and doors. :cool:

Or, what about "disco" mirror balls turning gently in the breeze? Throwing moving, bright spots back across their windows.

How can they possibly complain? :D

Chris, that's a good idea, especially as I have some large and small mirrors available.

I've also got some very powerful torch-lights and an air-rifle too (and I'm a marksman) but alas both of those would be illegal to use.

Luckily in my case, there are obstructions of one sort or another that prevent almost all direct light-pollution, other than the effects of sky-glow of course...

Cheers and CLEAR SKIES
Terry

Since we're talking extravagantly large equipment here, you could install your own "insecurity lighting" appropriately aimed at the offending party's domicile - this should do the job: a 1 million candlepower military surplus tank spotlight:

They should have nothing to complain about since you're just being part of the valued Neighborhood Watch program. If they complain, call in Code Enforcement:

That should take of the problem...

Hee - hee; just joking of course ;-)

Ha Ha Bob !!
There's quite a few answers to your suggestion. Some are certainly a tad frightening, whilst others actually giving me and idea of what I could do with some of my lighting-gear.

I have a signalling lamp from a Lancaster Bomber, which has to have a very narrow beam - so as not to attract the attention of the "Hun" and normally only be used to send in Morse Code messages to accompanying aircraft, as "radio-silence" would have been in operation - whilst over enemy-lines...

I have a 5,000,000 (apparently) candle-power hand-lamp - which also has a narrow beam - similar to that shown in your first image, so at least if used will not have the noise and fumes generated by the tank !!

But significantly, it would be nice to be able to use a real-tank to take-aim at the offender's lighting, then tell the offender to switch the ****** light off or pointed down, otherwise !*!*!*!*

Oooh AaaaH..

I have rode in an M60 tank. Back in 1981. Now the M1 Abrams has replaced the majority of them.
