Re: Problem with Lunt 50

Thanks Ivan for your latest reply and we can wait and see the outcome of further trials that you understand to try out.

GREAT CARE IN GETTING RID OF THOSE NON-SOLAR SPOTS, WHICH YOU CAN PROBABLY DO WITHOUT THE SUN-BEING OUT...

Re: Problem with Lunt 50

Ok Ivan, a little more research shows that the program SharpCap for downloading from camera to PC, will handle your QHY 5R ll C camera. I also understand that camera is colour, so inevitably settings will be very important and likely explains why the red-colour in your images is a tad over the top i...

Re: May 6 2021 Observations

Hey James, I've just opened you two PM's and thanks vm.
I've tried to return a PM to you, but as previously it is too difficult for more grey-matter to find a way.

So best to send ordinary emails - if need be, as much quicker and easier.

Thanks vm

Re: Problem with Lunt 50

Hello Ivan. Your first comment as:- "By the way, when I set it up (using the eyepiece) I have no change in brightness, i.e. at the same setting I see both the prominences and the chromosphere. Is this normal ?" Yes this can be normal if the Etalon is set at a midway-point between tuning fo...

Re: FireCapture versus Sharpcap?

That's a good comparison Mark and as you say "If it ain't broken don't fix it..."

I will spend some suitable-time/weather trying FC, but won't "bust a gut" trying to get a decent result.

Re: Problem with Lunt 50

Thank you Ivan, Unfortunately I can't use instagram on my systems here. I would have thought that just a few single-frame images as JPEGS might suffice.. What size EP are you using to fine-focus and/or viewing the Sun ?? Also are you using any FOCAL-REDUCERS or BARLOWS and their details, as well as ...

Re: Problem with Lunt 50

It might be prudent Ivan, to tell us what Blocking Filter you are using and also whether this problem appears using whatever Eye Pieces you are using ? Although initially this does sound and look like an Etalon problem, but more details as above, would help us diagnose the issue. If possible also le...

Re: FireCapture versus Sharpcap?

Thank you Magnus for your full comment on this subject. Firstly SC does have an excellent reticule-systems, which I always use to keep the Sun in the absolute centre whilst using either the two ZWO ASI-178MM cams or the Altair GPCAM for WL. The tracking-mount does in any case track very well over lo...

Re: deep-sky imaging session | TEC140 F/7 Alta U8300 Paramount ME

Very Very nice DS captures Pedro.
The camera is one to make me jealous and certainly proves its' worth too, even though I have the StarlightXpress HX916..

Thanks for showing these.
