I'm posting in the hope it helps anyone else considering a Daystar Scout SS60. The video's not quite representative of what one sees looking through the scope, but gives a general idea of field of view through a 24mm EP. When observing, much more prominence detail and surface texture is visible to the eye and the colour feels less red than it appears in the vid.
I'd have taken this video sooner if I'd realised that afocal video would work so well, so I'll try again next time the sun's available earlier in the day during better seeing. The video's taken by holding an iPhone against an Explore Scientific 24mm eyepiece and adjusting exposure (i.e. afocal video photography). Although I find a Plossl as easy (if not easier) to use as a wide EP for observing, it's simpler to align a smartphone with an eyepiece that has a wider field of view, for afocal video. Hence I used a 24mm ExSc (see below for detail). It seems a fairly quiet solar day, not long after the notoriously quiet 2020 and I believe is still close to the beginning of the sun's new 11 year cycle (hopefully it will become more exciting soon but not as exciting as having any Carrington Events pointing towards us).
I spent some hours, from late morning, watching these prominences form, dissipate and reform. The prom on the Western limb was very tall and bright, looking like a large rectangular tower block, which gradually split, faded as the top looped over to the north, then the top looped back again to the south. At one point this loop appeared to join - forming the outline of the head of a man, whose figure, with arms out, was clear and rather funny. Wish I'd taken this video sooner (or had the ASI183 to hand). The prom quietened and reached its current state (3pm ish) as seen in the video.
The long group of prominences to the South - 4 main and some smaller - were more dim than the prom on the Western limb initially, but they remained impressive, ranging from good to very small and appeared at one point to be as clear row of pine trees, especially the larger right hand prom, with spiky 'branches' and a distinctive triangular fir tree shape, which gradually brightened then faded to this view. The tip of the ‘sharks fin’ to the left of the group extended out to the east then receded.
I'm afraid it's not easy to see the detail in such a simple video - it's slighly more visible to the naked eye. By the time I took this video it had gone 3pm, there was more haze and a lower sun and none of the prominences were particularly impressive.
There were No sunspots easily visible, although a Plage appeared to be visible close to the Westerly limb. Little surface detail other than orange peel, despite tuning the scope (better with the SS60s dial to left of centre for this today). I still need to lots more time with the scope to get the best from it.
I'm a Ha beginner having only observed in whitelight before and only having used this scope twice before, once in combination with a ZWO ASI 183MC astrophotography video camera. Medium seeing, 6/3/21 'third light' on the Daystar Scout SS60 Scope with fixed chromasphere quark built in - 930mm f15 60mm.
Various Eye pieces used: Plossl 40mm, Meade Super Plossl 26mm, Explore Scientific 24mm and 11mm 82 and 68 degree EPs gave good clarity and contrast, but the seeing's not good enough for close viewing of proms. ioptron motor, roughly pointed north was perfectly sufficiently good to keep the sun in view for at least 45 mins at a time. I'll edit this post to add a pic or two of the equipment setup in a moment.
3 images attached are: Afocal Smartphone still image (contrast increased in smartphont), plus two shots of the setup.

Hi all,
My current image, still WIP, but I'm sharing this Hydrogen Alpha image as I thought it looked ok...
This is NGC3603 and NGC3576 (AKA The "Statue of Liberty" nebula), a massive H-Alpha region containing a very compact open cluster, located in the constellation "Carina" about 20,000LY away.
I took this photo on the night of 19th February 2021 using my cooled and full spectrum modded Canon 40D DSLR attached to a 80mm f6.25 refractor on a CGEM equatorial mount.
Exposure time was 3 Hours and 50 minutes (6x600sec, 6x900sec and 4x1200 sec subs), using a 7nm Hydrogen Alpha filter.
I'm still working on the narrowband color image, but this image is quite possibly my last image that I'll produce using just the DSLR before my ZWO2600MM arrives.
CS,
MG

A quick process of video taken of the Sun from Saturday (2021-02-27).
C9.25; CGEM; ASI385MC; Baader Solar Film homemade white light filter; Baader Neodymium filter.

Selling the Astronomik 12nm clip in Ha filter for 120€. Bought it for 270 usd including vat, customs and shipping so it's a really good price.
The filter is still in excellent condition, used only twice. No fingerprints, no scratches not even dust (image attached).
I will also handle the shipping through my post office without cost. If another shipping method is requested, then we'll have to to discuss the price.
Contact me if interested.
Clear Skies,
Anthony
