Andrew, thanks for the offer, in my case I already have some lens 6mm focus F:1.2 I’m trying to get F:’s of 0.8 to 1 which would match the 1 system I have up and working.
Thanks,
Eric
The telescope aperture could also be stopped down i.e. 4″ with all the other safety measures suggested above.
Eric
Good morning Dominic,
I’d be interested. I already have a heated security enclosures, lenses are proving difficult.

Over the years some of my doors have become super intelligent having absorbed information from such door stops !
Seriously though a good conversation has been struck up here with a range of topics which I have often sat down and tried to follow with some self learning.
I’ve gathered a lot of Susskind’s lectures etc. I’m aiming for taking one of the MIT’s open courses at PG level.Eric
Robin,
that is certainly encouraging for those of us contemplating SN hunting. M101 is a bright object regularly observed and that eluded discovery for almost 24 hrs. I’m close to having a 20″ Newt set up specifically for SN hunting. The biggest problem I will encounter I think will be a good, quick, and reliable automated method of checking images for suspects. If there any software writers interested in either a blink or image subtraction method or both I’d be interested in corresponding.

I think clouds have moved in, just as I’ve changed to a V filter for some photometry. A fresh S/N is a bonus for tonight I was trying out Astroart8 for telescope control, particularly for focusing. If it doesn’t improve shortly I’ll lock up for the night.

Robin thanks for updated links from which I have Id’ed the Super nova. Guess your onto it with the spectroscope.
Eric
Hi Robin,
Imaging M101 at the moment. C14 Edge+ QSI532 clear and V MEII paramount.
The link you provide doesn’t link through.

I once had a go at imaging M51 using clear,g’ and r’ sloan filters. A friend, Mark Large processed a small number of frames using Pixinsight.
clear 10 x 50sec. r’sloan 20 sec x 50 sec and g’sloan 20 x 50 sec.See the result on my BAA web page

Paul, thanks for your experiences with Astrometrica. I wasn’t aware that it did not run under WINE and the info re converting raw to fits is useful for me.
Thanks,Eric
Would not Astrometrica be ideal for stacking for asteroids or comets. When the MPCOrb file updated one can select the objects motion. The software is relatively affordable and there is a 100 day free trial. It’s a piece of software that should be in ones tool box in any event. The only reason that springs to mind that may be the reason for non use is the input file extensions (.fit) if DSLR type cameras are being used.
Grant would be worth your while taking a look at a chandlers (on line if your not near the coast) and checking out what’s available for cleaning GRP boat hulls. I’ve not had a boat for some years now so can’t advise on any particular item.
Regards,
Eric
Max, very nice work indeed. The advantage of having a good overseas site is obvious. May try and give it a go if we get a spell of good seeing as the nights get longer. Keep up the good work
This is sad news. I had been corresponding with Ron for the past couple of years with regard to my setting up an automated supernova patrol system for which he had freely and generously given advice and assistance in setting one up. I’m just about there and was trying to sort out some reliable software for the actual detection process.
We should search the night sky for with his passing there must be a new supernova somewhere waiting for detection.
Eric
Grant, If you control your camera via he sky X you should be able to do an automated T point run using image link. I do so with my SB ME mounts. Takes me about an hour to get 200 – 300 stars. I would have thought that once you have a working model, synchronizing on a star at the start of each session would get you going. The Paramounts are “homed” on a predetermined point at the start of each session which I think is similar to synchronizing Eric
Paul,
Indeed spectroscopy appears to be a growing and expanding area. It is something I would like to do. At the moment I’m not in a position to do so, but would like to learn. As far as I’m aware there are no remote rental facilities which could be used.
I’ve just acquired a rather nice 0.5m F:5 Newtonian reflector with Surrier truss OTA which I will erect next spring/summer and I would like to dedicate some imaging time to spectroscopy.
