Planning my first PST mod and need some help

Hi Now I have a new ITF, things are 'clear' ! What I wish to do is the obvious mod to use PST as a Quark and use it on various scopes, including my AR152 F/6.5 My 'practical' questions: 1. Do I need to warm tube to unscrew it from PST? I do not wish to break anything or scratch tube! 2. I do not wis...

Re: Solar FLAT for FULL Disc only - cannot seem to be able to use it

Hi
Sorry for my absence - I was sick then went on Holiday!

I tried various 'things', then I found my lunch box does the job!

I hope to find the time to keep testing and learning, then I will need to make PST mod [without cutting original tube] and use it with my various scopes.

Re: Solar FLAT for FULL Disc only - cannot seem to be able to use it

Thank you all for your expert advice - I am learning. I think I might have done it wrongly on that particular learning test. Regarding the full disc, I tried various covers and it seems the one that transmit most light is my 'current' sandwich tub! Got FLATS OK for full disk - finally. Still trying ...

Solar FLAT for FULL Disc only - cannot seem to be able to use it

Hi A quick (possibly stupid) question. I a learning and getting better and I normally manage OK to do Flats, but the only problem I have is with applying a FLAT on a FULL Solar disc. It is the 3-4 time I try and the flat it is always 'darkening' surface hugely when I add it in Autostakker [after cre...

Re: New PST ITF?

Ha ha ha ha ha ... Finally done it - with the O-ring too! The locking ring thread is NOT perfectly manufactured straight - it is slightly angled! I have taken filter + O-ring out, cleaned the threads using thin tweezers and then tried it without anything and found out the thread was not straight fro...

Re: New PST ITF?

Just got the replacement ITF from Maier. Which way should be fit? Just to be sure - I guess the Maier O-ring goes over the marked edge of the new ITF, but which way is the SUN side? Another guess: since the O-ring 'seems' to go on 'one' side only - as above, that must be the side where the screwed o...

Nice results there ... What an inspiring thread! :cool: I will be playing with my newly 'second-hand# PST and one day I will do stage 1 using my not much used Explorer Scientific AR152 F/6.5.

Re: PST + DSLR Full disk problem ... AMENDED

The pixels on your 178m are much better suited than the pixels on a 174m - 174m much better suited to longer focal ratios. Got it - thanks. I could have brought my PST to work this morning as SUN is very clear - idiot me - to test the adaptor with DSLR and 178M Hope tomorrow morning is decent enoug...

Re: PST Etalon Adjustment

I did receive them, but I have not replaced them yet. The other day I dismounted them again, as I remembered there were various threaded-holes in it and at the same time I found that article about changing where you place the screw. Well, to make it short I moved it from 1 to number 3 and now the tu...

Re: PST + DSLR Full disk problem ... AMENDED

If you can buy a new one, it seems the 174M is top with the PST! I am only using the 178M, because I own one and save me to spend more than I have. Which Skyris Model do you have exactly? I am no expert, but I might be able to help and in any case you need to add that Barlow Nosepiece [the tip of th...

Re: PST + DSLR Full disk problem ...

Personally, I wouldn't waste time trying to image in Ha using a DSLR results are mediocre at best. You need a short c-mount nosepiece https://www.ebay.co.uk/itm/Short-C-Mount-to-1-25-Barrel-Adapter-f-Telescope-Astrophotography-10mm-Height/323327080055?hash=item4b47cbb677:g:KaUAAOSw9GhYdZPW:rk:2:pf:...

Re: PST + DSLR Full disk problem ...

Hi Yes, I read that 'nice PDF' and it it is one of the things I could not try yet - because I do not have a Shorty. Therefore I used a 22mm Barlow tip and stupiditely forgot about the 35mm eyepiece holder he had and also mine is 30mm - so I need to reach 30mm. I think I am getting it now - I forgot ...

Hi Bart Yes, I know it is quiet although yesterday although I saw 3-4 prominences [one arching!] with other cameras. I am not talking about surface features, but simply DSLR not focusing on granulation and 'barely' focus on prominences - i.e. DSLR is not focusing and other cameras are. I cannot reac...

I know this is an old thread. I do need to replace the ITF from a second hand PST I managed to get. I have a few questions for the experts here, please. 1. I believe it is probably worth getting the ITF from Maier [out of stock] - not just for the price, but because it does not have the second prote...

Re: ARs on Sept 6

I never said thank you for your replies.

Gosh, almost a year passed and I am back trying to get more into solar!

I might get a Lunt 50 - if I can afford it.

Sorry again - I am too busy trying to put food on the table these days more than usual.
