Re: Alignment procedure for EQ6-R Pro question

Hello Franco, Never understood "solar align" for a mount. Isn't that just the same as just slewing to the sun (from the goto planet button) and then align with the control keys. I had to do something to make "Sun" appear as object under the planet button, but can't remember what. (think this was int...

Re: Weekend Sunshine and OaCapture testing for Apple

Good job Alexancra. FD's are great. I used oaCapture for a while on unix machines. (but switched to windows again where I got better USB performance) Overall it is a very good capture software considering it seems to be about the only one for an Apple :) and at least I know James so maybe I can get ...

Re: Quark Users

You are right Mark. This looks strange. The hatches also look unsharp (like something in the image train), so this seems different from what I have seen with my cam. (Should have looked it bit better at the image. Maybe time for new glasses)

Re: Quark Users

Hi Stu, Sony ICX178 or ICX183 chipped camera? With a 178 I get crosshatches that are visible in the image, depending on the zoom level; (They are there but getting more pronounced on certain zoom levels). This happens in narrow band imaging (small pixels, microlenses ...?) Never had it on the ASI120...

Re: 10 improvements to my solar telescope set up

That's a great video and setup Daniel. Specially liked: - the 90° gearboxes for the motor focus. Never would have come with that idea. - that you can handle 3 cameras in parallel. Your laptop / USB is very good Can you also record in parallel or does that slow framerates? Maybe an 11 th improvement....

Re: Basler Camera assistance

According to FireCapture website the Pylon SDK needs to be installed. (It's mentioned in the instruction video on FC's site). Don't think that is part of the Pylon Software suite.

Thanks, Mark for your detailed info.

I still do not see any cycle 25 evidences in my telescope in Ha.

When will we see even pores related to C25?

Re: Flats from near full disk?

The holy grail indeed ... I am surprised it even worked good, except for the solar edges. There is also some limb darkening effect that will "ruin" the flats (but maybe it helps to remove the gradient towards the limb?) Now I would try either one of the following: - Take the flats with the plastic b...

Hi Alexandra,

Good captures (and animation). I noticed these as well on Friday and it was indeed spectacular. For a short time these were even visible (very bright) almosts straight up. (Maybe 20 minutes, then only at lower degrees) Had no camera within reach. Pitty

2 small spots

The left one emerged already yesterday, so think we can call it a spot.
As seen today (24-06) with some high thin clouds obstructing good views.

Re: SharpCap overlaying a rippled filter effect?

Just one more question: the 120 is it a 120MC or 120MC-S (usb2 vs usb3) The USB2 (older) models deviated a bit from USB standards (something with buffer sizes, made it very fast even on USB2). On W7 this was not an issue, but from user reports I read this sometimes cause problems on W10 due to stric...

Re: SharpCap overlaying a rippled filter effect?

Hello, don't think this is the same as the "cross-hatches" seen with the ASI178 & 183. (These will change if you zoom-in or zool-out). If FireCapture does not find the camera, there must be something wrong with the camera installation. For the ASI 120 there have been different drivers in the past. (...

Hello Jordan, I don't have a ASI174 but had a look at the documentation: https://astronomy-imaging-camera.com/product/asi174mm There might be a way shortening the backfocus by removing the T2 ring, but then you will need to find a nosepiece with inner T2 thread (the supplied one has outer T2 thread....

Re: Omni xlt 120mm and quark

Impossible to get full disc with that scope and standard Quark. The blocking filter only allows full disc view with scopes with fl ~400mm. (I have a 80mm f/6 -> 480mm FL, does not give me full disc either, FL just a tad to long) An UV/IR (best a 2") in front of the Quark will do. Better a Baader 35n...

With the very long stock focuser and a 2" diagonal it will be ok. Wit focuser replacement you will n...

Never seen a rainbow like this, where a 180° span lasted for more than 8 minutes, and the secondary was also had 180° visibility for some time.
