Designed for H-Alpha solar observing and ready for imaging, this 40 mm telescope combines portability, precision and scalability in a compact format weighing just 2.6 lbs.<\/p>\n<p>Equipped with new-generation standards, each instrument is individually tested using precision metrology equipment. All performances, in particular the 0.35 \u00c5 bandwidth, are rigorously verified, guaranteeing consistent, reliable image quality.<\/p>\n<h3>A detailed view of the solar chromosphere<\/h3>\n<p>The LS40THa Enhanced Kit lets you explore the solar chromosphere in remarkable detail:<\/p>\n<ul>\n<li>Spectacular protuberances rising above the solar limbus<\/li>\n<li>Dark filaments running through the disc<\/li>\n<li>Active regions rich in magnetic activity<\/li>\n<\/ul>\n<p>With the included 12 mm flat-field eyepiece (33x magnification), you benefit from a sharp, high-contrast image. The major difference lies in its ability to maintain precise focus, ideal for prolonged observation and image capture.<\/p>\n<h3>Key improvements for imaging and precision<\/h3>\n<p>The Enhanced kit features two major evolutions:<\/p>\n<ul>\n<li><strong>B600 blocking filter :<\/strong> 6 mm clear aperture, providing more back-focus for sensors and reducing vignetting<\/li>\n<li><strong>Rack &amp; Pinion eyepiece holder :<\/strong> CNC aluminum\/brass design, smooth motion, integrated brake and load capacity from 6 to 8 lbs.<\/li>\n<\/ul>\n<p>The rotating eyepiece holder allows optimum framing, while the brake system ensures perfect focus retention, even with heavy accessories such as cameras or filter wheels.<\/p>\n<h3>A telescope ready to evolve<\/h3>\n<p>Like all models in the 40 mm range, this telescope is compatible with a double stack system. The addition of the LS40FHa filter achieves a combined bandwidth of less than 0.25 \u00c5, considerably enhancing the contrast of surface details.<\/p>\n<p>The LS40THa Enhanced Kit is therefore perfectly suited to users wishing to move into advanced solar imaging.<\/p>\n<h3>Complete kit contents<\/h3>\n<ul>\n<li><strong>LS40THa OTA :<\/strong> aperture 40 mm, focal length 400 mm, f\/10, tilt-tuned front standard, bandwidth 0.35 \u00c5, unobstructed aperture<\/li>\n<li><strong>B600 blocking filter :<\/strong> 1.25\u2033 angled lens, 6 mm clear aperture, optimized for imaging (extended back-focus, reduced vignetting)<\/li>\n<li><strong>1.25\u2033 Rack &amp; Pinion ocular holder (1:1):<\/strong> CNC aluminum\/brass, 0.5\u2033 stroke, rotary, adjustable integrated brake, brass clamping ring, 6-8 lbs capacity<\/li>\n<li><strong>SunLock solar finder:<\/strong> red dot projection, glass reticle, 3-point adjustment, red anodized aluminum<\/li>\n<li><strong>Vixen 4\u2033 dovetail:<\/strong> black anodized aluminum, 2 x 1\/4-20 threads, universal compatibility<\/li>\n<li><strong>Hard case :<\/strong> aluminum, dimensions 18.5\u2033 x 10.5\u2033 x 7\u2033, custom foam protection<\/li>\n<li><strong>12 mm flat-field eyepiece :<\/strong> 1.25\u2033 casting, 60\u00b0 field of view, 5 lenses, AR 0.1 % coating, 33x magnification<\/li>\n<\/ul>\n<h3>Summary table of technical specifications<\/h3>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"8\">\n<tbody>\n<tr>\n<th>Features<\/th>\n<th>Detail<\/th>\n<\/tr>\n<tr>\n<td>Type<\/td>\n<td>Dedicated H-Alpha solar telescope (daytime use only)<\/td>\n<\/tr>\n<tr>\n<td>Opening<\/td>\n<td>40 mm, full aperture, unobstructed<\/td>\n<\/tr>\n<tr>\n<td>Focal length<\/td>\n<td>400 mm<\/td>\n<\/tr>\n<tr>\n<td>Focus report<\/td>\n<td>f\/10<\/td>\n<\/tr>\n<tr>\n<td>Standard type<\/td>\n<td>Front-mounted, tilt-tuned<\/td>\n<\/tr>\n<tr>\n<td>Bandwidth<\/td>\n<td>0.35 \u00c5 (individually tested)<\/td>\n<\/tr>\n<tr>\n<td>Double stack<\/td>\n<td>Optional (LS40FHa), &lt; 0.25 \u00c5<\/td>\n<\/tr>\n<tr>\n<td>Blocking filter<\/td>\n<td>B600, 6 mm clear aperture, 1.25\u2033 format<\/td>\n<\/tr>\n<tr>\n<td>Lens holder<\/td>\n<td>CNC rack 1.25\u2033, rotary, integrated brake, 0.5\u2033 stroke, 6-8 lbs capacity<\/td>\n<\/tr>\n<tr>\n<td>Eyepiece<\/td>\n<td>12 mm, 60\u00b0, 5 elements, AR treatment 0.1 %, magnification 33x<\/td>\n<\/tr>\n<tr>\n<td>Solar researcher<\/td>\n<td>SunLock, red dot projection, 3 screw alignment<\/td>\n<\/tr>\n<tr>\n<td>Dovetail<\/td>\n<td>Vixen 4\u2033, anodized aluminum, 2 threads 1\/4-20<\/td>\n<\/tr>\n<tr>\n<td>Briefcase<\/td>\n<td>Aluminum, 18.5\u2033 x 10.5\u2033 x 7\u2033, custom foam<\/td>\n<\/tr>\n<tr>\n<td>Weight<\/td>\n<td>\u2248 2.6 lbs<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Why choose the LS40THa Enhanced Kit?<\/h3>\n<p>The LS40THa Enhanced Kit is the ideal choice for astronomers wishing to combine visual observation with solar imaging.
