good news.
I've just heard from Lunts European distributer and they have offered to send me a replacement ITF, and have provided simple instructions on how to replace the glass. Excellent service.

Allcart

This is the cracked glass. Not heard from Lunt yet, so not sure exactly what the glass is. I'd like Lunt to verify that it is not an ITF. I'll phone them later.

Allcart

Thanks Walter, I'll email Lunt and see how much it will be to fit a replacement.

Allcart

can anyone tell me what the first piece of glass inside the drawtube is for. It has a green tinge to it. I have a crack across mine. It does not seem to effect the image quality and I have not noticed any difference visually or when imaging. Is my B1200 still safe for visual observing. Incidentally,...

I decided to set up the 120mm XLT Lunt60T Mod on Saturday, ready for a blazing Sundays broadcasting on NSN, so after re-collimating it, i managed a quick capture between clouds. This was taken with the Modded 120mm Luntmonster, a DMK31 and x1.6 barlow. The shape of the active region intrigued me so ...

Allcart

yes I agree, its hopeless. I don't know why I bother anymore.

Outstanding imaging.

Allcart

Great detail in these images Valery. I can find no information of your setup or your Aries solar kit.
Could you share some details.

Allcart

no problem getting a B1200 on its own in the UK. I just got one from http://www.iankingimaging.com/ He doesn't list them, but a simple phone call and tell him what you need will solve the problem. Not cheap though. Incidentally, I use a B1200 with my pst mods and have not noticed any problem. I have...

You didn't say which scope Derek, but an Skywatcher autofocus can be fitted to most crayford type focusers. If you are stateside, then the Orion Accufocus is the same. I fitted a Skywatcher Autofocus motor to my Lunt feathertouch with a belt drive. Works fantastic and the adjustment is very fine and...

Well done for capturing this event George. I only got to see it on GONG, but it was a good spectacle. There was an almost simultaneous eruption on the limb which almost blew the tree prom apart..

Allcart

Very nice John. The prom looks very distinguished standing out on the limb. Great detail.

Allcart

Also try wrapping some masking tape round the part where the strap wrench grips. It provides more grip for the rubber strap.

Some stunning pics of our universe including a superb pic by Ralph Smith

Congrats Richard, probably the best Xmas present you could wish for. Enjoy it and post a few pics when you get it.

Allcart

Excellent news Stephen and well done to everyone who donated. I'm certain there will be more donations to come.

Allcart

Good job George. you have got some good detail. Not a fluke, so keep it up.

Allcart

Lovely closeups Ralph.

Allcart

Looks to have potential. You just need a better day for a test.

Allcart

Interesting and inventive. Hope you get some sun soon.

Allcart

Yes I saw that too Mark. It seems we had a sudden rush of donations overnight. Its all good.

Allcart

Wow thats a neat little focuser. I wonder how that works. Maybe Ralph could enlighten us about that as well.

Allcart

We were warned on another forum Walter. But honestly, at those prices it would have to be. A Lunt60T with PT, feathertouch focuser and bf1200 for £863.00. And they only accept bank transfer, so absolutely no protection. Trust me Walter, its a scam and they have been doing it for quite a while. Googl...

Allcart

Ever dreamed of getting a bargain. Take a look here, but DO NOT BUY.

Its a scam site, but if only it was real.

If you're trying to find the -200mm position for the etalon John, measure 200mm forward from the focal point to the front of the rubber tuning ring. If you already have the measurements then I guess from the centre of the OG is best.

Allcart

Ken is right Lou. Your method of finding the initial focus point and then finding the position of the collimating lens is ok. However, when the etalon is inserted into position, the focus point then moves and becomes 200mm from the rear lens of the etalon. The rear etalon sits between the black arro...

Allcart

I think your first step should be to measure the length of the drawtube. Based on your measurements, the front lens needs to be 5.5cm into the drawtube to to be at -200mm when at focus. If your drawtube is very much longer then the lens may be too far from the etalon to operate efficiently and may e...

Allcart

Lovely Derek. I've seen lots of pics produced by your 'old girl' and they are allways brilliant. That 'old girl' does a fine job.

Allcart

good plan Richard. If you have any good ideas for this, please share. Its something I'm thinking about for next summer too.

Allcart

I don't think Alexandra will let me pilot the big gun. There is a lot of £$£$£$ of equipment there and she doesn't trust me to operate it correctly.

That bit made me laugh. It would normally be the other way round.

Allcart

congrats on a great start. You have learned your craft well.

Allcart

Those are good pics with the new cam Ritchie. Is this the colour version? Why the change from the DMK31? Whats the difference in image scale?

Allcart

I don't understand how using ROI can increase framerate either. Can some explain in case I'm missing something fundamental.

Allcart

Thats a great result and terrific Mod Ralph. Can't wait for details of the filter and construction. I have a 6mm pst blocking filter that is crying out for an upgrade.

Allcart

Ha ha ha Stu, I did exactly the same thing with mine. You're never alone mate.

Allcart

Excellent detactive work walter.

Can I just say..........Here we go again Mark. :cheer:

Allcart

Cracking image Howard. I had to really look hard to see any banding. If you hadn't mentioned it, I would never have noticed.
Job well done.

Allcart

Fantastic. :rockon: :rockon:

Allcart

Excellent image. Very crisp and clean and no sign of any joins. For 19 panels that is very good.

Allcart

Excellent set if pics Pedro, love them all.

Allcart

That was a very interesting video. So the cleaning has to meticulous, can you imagine how you are going to do that with those tiny spacers.

hmy: You can barely see them, let alone clean them.

John; I wouldn't worry about how the tuning is done, it will do your head in.

Allcart

How did it decontact Rob??

You do have a good excuse to mod the LS60 now. It will be quite cheap as you have all the bits.

Allcart

Lonely Girl...I remember someone writing a song about you Alexandra.
I was optimistic too. I set up the scope and just got enough sun for a quick focus and that was it. never really got a look.

Allcart

Not too cheap I hope.

hmy:

I'm not an optics expert, (far from it) but i wonder if you found an airspaced doublet and just used the front lens, would it work.??

Allcart

Hi John, all the info i have seen states that the lunt has a 60mm singlet chromatic objective. I don't know if your 100mm singlet will work as a replacement for the 60mm. You would obviously have to find out the focal ratio of the lens and mount it at its optimal position relative to the etalon. If ...

Allcart

Good answer Stephen, stick to this software format. Its simple to use and easy on the eye.
Spend the money on something more important.

Allcart

Congrats Gabriel. Superb image.

Allcart

Hmmm, 10AM EST means little to me John, I can only deal in UTC.

Allcart

Not sure when you captured the FD shots John but there was a huge M class flare about an hour before you posted this series. The flare almost reached X class status.
