Re: Decent sized proms on Oct 9

Thanks. Marty

I use the Quark to double stack the Lunt 152. If a "double limb" appears, it's the result of separating a single image into disk and prom layers and processing them separately.

Decent sized proms on Oct 9

All images were taken with a Lunt 152 + Quark Chromosphere and Blackfly S 5.1 Mp camera. The larger scale images used a 1.5X barlow. I had a half hour of moderately good seeing before the clouds rolled in. Lou 757.jpg 752.jpg 607.jpg 603.jpg 555.jpg 517.jpg 460.jpg 460-.jpg 411b.jpg

Re: Gorgeous Prom Groups Today, HA 120mm, Oct 7th 2018

Very impressive proms putting on a show and beautifully captured, especially appreciated being under cloudy skies here for the past many days.
Tuesday coming up looks promising and I hope there are some worthwhile features appearing.

First light with Blackfly S 3.2Mp

This camera (Blackfly S, 3.2Mp) was used with a double stack setup I've used only once before, LS80 + 3X telecentric + Quark Combo in back. This allows use of LS80 in a double stack configuration and at full 80mm aperture. I usually double stack the LS80 with an LS60F in front. Because the Quark Com...

Re: H-alpha 30092018, first light asi290mm

Hi, Bart

From the FLIR spec sheet on their website the QE for the Blackfly S (5.1 MP) is 76 at 525nm. The QE of your 290 is stated as 80 on the ZWO site but the
wavelength is not specified.

Thanks, SkyBurner I was very aware of potential eye damage in removing the blue glass. I only do imaging since in my area good skies are very rare.

Hi, Bart Congratulations on your new instrument and great first results. I had some questions about your BF mod and the camera itself. Is the blue glass on the telescope side of the BF1200?

Some nice limb events from Sept 29

Again plagued with very jittery seeing along with gusty winds and pesky clouds, I set up anyway and pulled these images out of the session. Enlargement will show sharpening artifacts (a grainy texture) and so these are best viewed at low display scale. I used an LS152 in single and double stack mode...

Used on its own with the c9.25(at 4600 mm), my Quark Combo produces a fairly even but very flat (weak contrast) image. When I use either one of the 2 PST etalons I have on its own, I find the image to be much less even and very sensitive to slight amounts of tilt. Combining the Quark Combo and eithe...

With no possibility of decent higher res imaging (although I tried), I settled on a full disk image taken with an LS80 at 1120mm I'm continuing efforts to try and find the best double stacking arrangement with my c9.25. So far, I found the best combination that provides decent image brightness is to...
