Re: Sol from the 24th of June 2018.

How much contrast in your images, Eric. Are you using your Meade at full aperture ?

Full discs with LS50 and TS80ED

Solar activity is returning to be very low as AR12715 is approaching the W limb. There are few prominences on the limb (yesterday there was a fine one on the W) and a filament is visible on the disc inside a large area of magnetic activity but without details in WL. This morning I counted 7 spots in...

Re: Fridays Full Disk 22nd June

A uniform disk, Mark, with much contrast. The large spotless active area to the east is also well defined.

Re: New activity on the Sun

Thanks to all. Quark Calcium is a good device, I am very happy of it. May be it gives less contrast than the corresponding Ca-K modules by Lunt, but it costs less and doesn't have the oddities and the defects of the Quark Chromosphere and can be used with my solar newtonian also. Making some experim...

New activity on the Sun

Hello Today four active regions are visible on the Sun raising Wolf number to about 60. AR12713 is really hard to die, few days ago it seemed almost faded away, instead new small spots are still appearing. AR12714 changed a little between yesterday and today while activity in 12715 increased conside...

Re: Question

Paul, my own Quark doesn't show any foggy zone, even when off band, so the behavior of your unit could be due to "something" trapped inside (I can't say exactly what and where) or to some inhomogeneities of the etalon. In the clear areas of your images your Quark doesn't seem to be badly off band. H...

FD's and AR12712

AR12712 is now of B class (although it is still officially labeled as a C group), I couldn't observe any defined penumbra around the main spot, however this morning I observed 18 spots in the 80mm scope, most very small. In WL there is no much else to see and the disc is almost entirely blank, but i...

I installed the FT crayford focuser and I no longer have the original one, so I can't compare them. Sorry.

Re: Help! Tiltadaptor and Lunt LS50..

OK, my LS50 reaches focus with the tilt adapter, provided the short C-T2 connection is used.

Re: Help! Tiltadaptor and Lunt LS50..

The problem is to reach focus with the tilt adapter inserted between diagonal and camera. Baader Planetarium sells an ultra short C-T2 adapter, I use it to focus my Chameleon and taking full discs with my Lunt50, I'll try it with the tilt adapter in place and I'll let you know.

Re: Some activity of May 23 & 24

Thanks to all. I observed 12712 this morning and this afternoon, it seems still growing with small new spots added but I couldn't detect any major activity. AR12711 seems quiet now.

Re: Sun 2018-05-24 New AR's

Paul, ask Teleskope Service for a large photo foil, recently a friend of mine has been able to obtain a 50x50 cm piece. May be it was the last available but it's worth a try.

Nice images, Paul, may I suggest to use a ND 3.8 with your C8, this would allow shorter exposures and improve sharpness.

Some activity of May 23 & 24

Finally there is something interesting to see :) three active regions each one with sunspots is a rare opportunity during a solar minimum. AR12711 shows about 18 spots, some very tiny but the main one has a well defined penumbra. The AR that emerged yesterday from the E limb is flaring with B- and C...
